115 2 Stroke Yamaha Question

[fishfighter]

don't know anyone in lc but i am sure some people will chime in soon, props do wear out too, getting in some shallow water, sand and mud will wear out a prop you can lose some blade which will affect performance, if the motor doesn't get used too much it could be your carbs also, does the motor idle fine or is it rough, maybe an issue with low speed jets or somthing

Boat doesn't get used much...Forgot about idling. Rough, always wants to die out

I have the same engine except 2 years older. It has been very reliable and has performed well for many years. The only problem I have had is an overheating problem caused by crud getting into the cooling channels. I run a 19 foot center console and have never had a problem with the hole shot. if it is not the prop, I bet you may have a fuel or carburetor issue. To me, it would be worth getting it checked out.

Def have someone do a carb job, just cause it runs doesnt mean it is running right, you can damage your motor running it with dirty carbs

do a compression test and make sure you are firing on all cylinders, its easy for these motors to run without one cylinder and not be noticed.

in the old days if you lost a cylinder it would run really rough but these new motors with electronics and all that they can still run smooth

also replace all fuel filters and run some fuel system cleaner in it.

if its just old then switch to premium fuel and it will help out a lot.

replacing the prop will help your hole shot and get your performance back to where it needs to be to give you more years out of the motor. a new prop is a lot cheaper then a new motor.
