Tohatsu 40TLDI
 

Anyone have or had a 40 TLDI? How is the performance? Can it be hopped to a 50? Are there any year models beter than others to look for? Might be replacing my 25-3cyl Yammie. Thought about looking for a used 2 cycle, not sure if i want to go to 4 cycle yet. Thanks for any info help.

Just what the Dr ordered in the classified section.
Great motors! Close to bullet proof! Been running one for a couple of years now. I'm sure this one has already had the restrictor plate removed so it will be very close to a 50 already.

Give Kyle a call

Wow that was quick, one was just posted in the classifieds!!!!!!!! ;)

Yep, Here's the one that just posted a few minutes ago.
Thanks for the heads up H2OFwlKlr

06 TLDI
 

I got a 2006 40tldi on a 1652 alweld 13 pitch prop no jackplate or trim tabs and i do 33mph. Love that motor great on gas and still have 2 stroke power for the most part. The only horsepower upgrade you can do from what ive been told its pop out the restricter plate in the air intake. I did and only gained about 1-1.5 mph.

Bayou, that's about right. We figure 5hp=1mph gain on must fishing and hunting rigs.


Cajun: Have you considered a tohatsu 40/50 hp 4 stroke. This is a test run last week. 1548 Ambush, 40/50 Tohatsu 4 stroke, 18 pitch Turbo Hot Shot prop, 50.4 mph. Has a great hole shot. I can find nothing to dislike about this engine. I have run one since last fall, love it. Quiet, sips fuel, great holeshot, great top end, not your typical 4 stroke. FIVE (%) year warranty on these engines.

"40/50 Tohatsu 4 stroke, 18 pitch Turbo Hot Shot prop, 50.4 mph.".....is this speed on a stock motor??? My 25 Yamaha is on a 1550 marshrunner and runs about 32+/- with me and my gear in it. Course it hasn't been in the water since Rita due to other issues, currently reworking my boat and trying to get it back to fishing. Debating about keeping my 25 to run the burns or going up to a 40 since that is what the boat is rated for. Loved the way it ran before, just seemed to need a liitle more oooommph for the glass boat.

This is exactly like you pick the motor up from Lake Area Marine. An 18 pitch would not be my choice for the marsh, but we were trying to prove a point, and we did. I have run this engine since last fall, love it. It is the strongest running "40" badged new motor on the market. The motor is a 40 until a restrictor is pulled, it then becomes a 50. Sweet motors. We actually ran a bit faster than that with a 25 pitch cleaver. The motor had no trouble getting the boat on plane, spun the 25 just fine. They are strong engines.
I tested that unit last fall, it performed flawlessly, 25# water pressure, idiot proof, the ecu shuts the engine down when overheated.

Here's the run with the 25 pitch 4 blade cleaver. Motor had no problem turning it. Boat ran high and dry. We never let off the throttle or touched the trim to go around the curves in the river, great handling boat:

Did ya'll forget to turn the recording mic on??? Dang that thing is quiet!!!! Now you done gone throw another monkey-in-the-wrench!!! This is really going to make it hard to keep my 25, just might have to check on costing.

For some reason I can't see your video's on you tube... Are you running an empty boat or 2 people with ice chest and all gear to fish for a day ????? From what your post say the bass masters ought to be running tahatsu's ...There is a big difference between running an empty hull for a race and a hull for a fishing situation....How many rpms are you turning compared to what the manufacturer says should be turning????

The manufacturer sets the rev limiter at 6150. I don't recall mentioning Bass Masters???? There are very few people that run CLEAVERS for joyrides. They are pretty much built for speed, ONLY! We have tested a few different hulls, very few will run mid 40's empty. These are fishing hulls built for performance. I'll let you know how it runs after mine is set up. I run 2 large deep cycle batteries, 82# thrust motorguide, 120 qt. cooler, fishing junk enough for a week. I'll get i5t rigged, run, and let you know how it runs loaded.
We were testing the boat more than the motor. We are running an empty 100 gauge, 405 pound boat with a full size battery, 6 gallon fuel tank, 200 pound driver. I appreciate your insight on the differences between a race boat and a fishing boat. BUT, I fully understand the difference in a race setup and a fishing rig, I raced professionally for almost 10 years, didn't use a trolling motor very much on that boat:D There are still very few aluminum fishing hulls that will run over 50mph empty.
You see, this is a fishing boat:

And this is a race boat:

Please don't take my ramblings seriously, they were not meant seriously.

Never said you claimed bassmasters ought ton run tohatsu's....The way you put it on your post one would think they should...More than once here you boasted on these motors for their speed they put out but thats not a real life fishing boat...I am by no means knocking the performance of the motor but in a real life fishing situation you are not going to get 50 mph. out of a 40 hp. motor...If you do then how long is it going to last ??? A rev limiter is different than an operating rpm...I have a 70 yam. that tops out at 6100 but I'm sure it won't last to long running that rpm...Golf carts have rev. limiters on them...Again I am not knocking the motor but the way you put it everyday people can put this motor on their boat and expect to run 50 mph. and it aint so...

Lil bubba if you ever get a chance to run this motor do it. Its a beast! I have one and love it I run a 1652 alweld marsh special with the 40 4 stroke. I ran with all my fishing stuff,ice chest batteries every thing for a day on the water and hit 39 @ 5860 r.p.m. Went the next day with me and my son ran 37 mph. Its fun watch CajunChristian work his magic on the videos that he posts.

Like I said, we were testing the hull more than the motor. And yes, I have tested quite a few hulls and outboards of different manufacture, so I know a high performance hull when I drive one, empty or loaded. If folks can't look at that video and see no trolling motor, no rods, no partner, NOTHING normally carried fishing, then I surely can't help them. The motor was tested last year.
You asked if we turn the motors above recommendation, how long will it last. I can answer that question from EXPERIENCE. My race engines were STOCK 50hp tohatsu 2 stroke engines. Manufacturer called for 5400-5600 rpm. I raced that class for 5 years with the same 4 STOCK blocks. Turned them 7200-7400 rpm every race, never broke a single part on the motors. Longevity, our longest race was a marathon, 40 laps of a 4.1 mile course. So for 164 miles, that stock block turned 7400 rpm on less than 2 pounds of water pressure, no failures, EXPERIENCE! My last outboard was a Mercury prototype. A 4 cylinder, 61 ci, 4 stroke, 40hp unit with a 60hp ecu in it. The engine burned a valve after a tad over 2400 hours. That ecu was read, over 2400 hours, 97% of the time at 100% throttle, hit the 6250rpm rev limiter over 460 times, shut down on overheat over 360 times, then burned a valve, that took almost 10 YEARS.. EXPERIENCE!
I never insinuated that anyone could load a boat down and run 50 mph. I will insinuate that very few aluminum hulls will run even close to 50mph, EMPTY, with the exact same engine. We test hulls empty FIRST, to see if they are even worthy of the label "high performance", the majority are not. If the boat runs 50mph empty, it will run in the 40's loaded, very few others will do that. I simply try to disseminate the information we gather, take it as you will. Most folks will have enough common sense and vision to see and know that we are testing empty boats, evidently some will not.
If you are afraid to turn your engine over the manufacturer's recommendation, great. I give results on tests I have performed, not read about, not told about, not suggested by the manufacturer, I performed the test, that is called EXPERIENCE! So I can give you "real world" experience. You talk as though you have never exceeded the manufacturer's recommendation, then how do you know how long the unit will last under extreme pressure. You see, you are speaking from conjecture, I am speaking from experience. I am not trying to disrespect or argue with you, I am stating the facts. I have tested outboards under extreme operating conditions since the late 80's, EXPERIENCE!

You are correct , I have not exceeded manufacture's recommendations . My "EXPERIENCE" with diesel , hydraulics , and gas since the early 70's would have gotten me fire'd to do so....I do have "EXPERIENCE" with others who thought they knew better than the manufacturer... I was simply stating there is a difference between running a motor on a performance hull and running it on a regular boat . The way you put it in some of your post one can get the same from either and it ain't so...

You are absolutely correct in whatever you say:D
Have a wonderful day.

Come by the boat show, I'll buy you a coke:)

CajunChristian...if you are familiar with the 1550 Marshrunner that Clay used to build in mid-90s, what do you think I could expect speed-wise from the new 4 stroke Tohatsu 40 with it rigged for fishing and 2 batteries?

You will probably see upper 30s Cajunyoung... maybe 40.... is it the squared off tunnel?

mine has the squared off tunnel with the overhanging flared backset transom....make sense? it looks like the transom was moved back from the "normal straight across" position with angular sides to make it act like a built in jackplate....sets back about 10" or so if I recall correctly.

I had a 93 with the flat transom. From talking with others, the flat transom performed better than the setback transom.

Cajunyoung we have the same boat then! they are not known for speed at all! but they are very stable and get pretty shallow... Id say you will run in the upper 30s with with a new 40 4stroke... just a guess of course... The flat transom marshrunners were def a faster boat.

Those marshrunners are heavy boats. If I had to guess, mid 30's. Anything more than that is a bonus. You may wind up turning a 14 pitch prop. That motor with a 14 will get on plane in about 10' distance and hit the rev limiter within 50 yards. You could go to a 15, hole shot will suffer. You may need to do like most of us do, have a river prop and a marsh prop. These units have a 2.08 gear ratio, that usually means that they turn 1" pitch higher than the old 40's and 50's we used to run, they had a 1.93 or 1.95 ratio.

I always thought that it seemed a little slower than it should be but i have been very happy with it. For the size, its the most stable boat i have had, love that i can stand on the edge of the deck and not have it rocking on me. Thought about selling it a few years ago, but decided to keep it and rebuilt the transom myself. Just thinking about maybe putting a 40 on it now since Lacassine allows it.

When the boat was running before, i had clocked it on my handheld gps at 32 - 33mph rigged for fishing with just me in it on the Calcasieu above Moss Bluff bay. I like my 25 Yammie, and it does okay for a heavy boat, but it always seemed just a little bit short out of the hole. Thank you and everyone else for the advice, i appreciate the opinions.

Another difference to note is the 4 stoke water pump is stronger than the tdli. i have a tdli and love the heck out of it. However in the shallow stuff or grass alarm goes off too easy and engine starts to cut out as a precaution. Cajun Christian has stated the water pump on the 4 strokes is superior by far compared to the tdli.

Thanks, that is definitely a big concern because of fishing in the marshes so much.

I sometimes joke that they stole Mercury's water pump. My 2 stroke Tohatsu's would pump about a dribble at idle, 7 pounds at WOT. The 4 stroke pumps 3-4 pounds at idle and 25-26 at WOT. Love the water system.

Cajun I have a 1648 alweld semi v and I am in the process of having the Tohatsu 40 HP 4 stroke put on that hull now. What prop would you recommend putting on it?

I am in the process of having one installed on a 1648 semi vee hull what prop set up do you think will be best to set up for fishing and hunting rig

Well, just an update....i want to thank everyone for their opinions, suggestions and information. Went to LAM lasr saturday morning with some questions and got my answers. Talked to Gerald, very helpful and knowledgable person. Decided to go back this coming saturday and get the Tohatsu 40 4stroke for my marshrunner, gonna sell my Yammie, will miss it too. So i may call on ya'lls expertise about setting up a new motor, thanks!

FYI I had 50 TLDI Tohatsu on my 1852. Replaced it with 40hp Tohatsu Four stroke and the four stroke ran faster with equal hole shot same boat same load.

CajunYoung let me know how that 4stroke works out for you.... I wouldnt mind putting one on my marshrunner.

i'll let you know how it does, but it may be a couple of months yet till I get the boat finished and in the water. I am buying the motor now for the pricing and then rigging it later when the boat is ready. did you get my response to your pm a week or so ago? I replied but it never showed that I did, so not sure if it went thru.

no i never got it

Hello everyone just an update picked up my boat from Lake Area marine with the 2015 40 hp 4 stroke Tohatsu on it. Put in at launch and ran it for a couple hrs to on my 1648 semi vee hull .100 gauge. I am very impressed with the motor I had a 2 stoke 40 Tohatsu with ports opened up and 50 carbs installed on it. Once I ran it for several hours I wanted to see what it would do. Do not ever let everyone tell you there is no hole shot on these 4 stroke motors. In about 20' are less its on step and it runs 40mph with a stainless steel Yamaha 15 pitch prop with 2 batteries in front 1 battery in back full tank of gas and trolling motor. Very impressed with it gonna try 16 pitch prop this week if this rain lets up.

What did that boat run before with the 2-stoke 40hp?

I was running between 38-40 but there had been a lot of work done on the 2 stroke. These new motors are strong and they have a lot of low end power the gear ratio in the foot has been changed makes a big difference.

I have run that same unit since last year. I can't find anything I don't like about it. I love everything on the tiller, a LONG tiller.
I got a chance to run a NEW 25hp 4 stroke Tohatsu. It was a rocket. I was very impressed, seems like Tohatsu is listening to it's customers. The 25 on a 1544 AlWeld ran 34 mph with just me, banging on the rev limiter, put Kyle (275+#) on the front deck, motor ran 32.4 mph still on the rev limiter. With a little setup time and the right prop, this will be a legitimate mid 30 mph boat loaded for fishing. It is almost running stock 40hp speeds. That's impressive compared to anything else on the market today. Doubly impressive for a 4 stroke. From dead stop to on plane was just as quick as the 40-50 tohatsu, I was impressed. For the guy that is in love with fishing Miami Corp, this would be the motor to have. I didn't have a chance to measure water pressure, but it was light years stronger than the old 2 stroke tohatsu. I plan on data testing this unit for Lake Area. The numbers will be interesting. I throw that out there for guys thinking about buying a 25 and just don't know where to start looking. Start with this one and then compare everything else to it.
D

Yes water pressure has come up a lot on the water pump and it sips gas they have listened to some one for sure they have made some great improvements on these motors. That is very impressive for a 25hp for sure mid 30s that's awesome.

Your posts always make me want to buy stuff I don't need.

Agreed

Have you ran the new 25hp on a 1648 alweld yet? Whould love to put one onto boat.

I have a 40 TLDI on my 18x48 Eric boat and I'm doing 39. 14 pitch powertech prop. Best motor I have ever owned. Hands down. It's the bomb.com

Yes they are listening to the customers for sure they have made a lot of changes and its all positive. I love the
Big tiller handle as well my new prop will be in next week Kyle thought he had one but he didn't. I think it will handle the 16 and increase speed a little as well hope so any way don't won't to loose hole shot for speed hopefully it will preform like a champ. What tachs do people use on these motors will a tiny tach work are is there something else?

Id assume tiny tach would be fine.
