Ride on 18's with brackets?

Sorry for the typo. I meant OptiMax 125. The OptiMax 75-125 all use the same 1.5 L block and are advertised to all weigh the same. Therefore i thought it best to opt for the 125. More power and the motor would not have to work as hard.

True, but sometimes the higher output models are tuned/optimized for higher rpm to get the extra hp, and may actually have less torque at lower speeds where you need it to get on plane, so the "more is better" thinking isn't necessarily correct. Depends on the application, so need to think about how you really use the boat and not just top speed!

The 90 hp E-TEC is a 3 cyl/1.3L engine (1/2 of my V-6) that weighs 335 lbs w/25" shaft, with 2.25:1 gear reduction, so it can swing a big efficient prop.
