Then you need to play with props. The 3 cylinder, EFI, 4 stroke 40hp Merc has a 2/1 gear ratio. I propped mine to run loaded, it will bang the rev limiter empty. BUT, it pushes an 1844 Alweld marsh tunnel with 3 men, dog, and hunting gear 30 mph. Gets on plane in about 15 feet distance loaded. I run loaded 90% of the time, so I don't care how fast it runs empty.
For my 1556 with the 4 cylinder, 4 stroke Merc, I run 4 different props. I run a 14 pitch 4 blade prop in the marsh, gets on plane in the length of the boat, then hits the rev limiter in about 50 feet. In the river, I run a highly modified, pitched up 16 pitch Yamaha semi cleaver, average pitch is 18.
Just for giggles and dares, I run my old short course race prop, a 12" diameter, 20 pitch Quicksilver cleaver. Takes 30 yards to get on plane, then put the cat outside and hang on.
First thing to get is a tach, otherwise you are guessing.
