Re: old question…mounting height for pontoon motors

[johnyrude200]

I built a deflector and mounted the motor lower, and both issues were solved. HOWEVER, I used a tach and the motor has only hit around 4300RPM, which is 700RPM below the rated specs, and I can only hit about 14mph.

So this is the last week I get to swap out props (it’s been low 50’s to low 40’s for daily highs here in cowhampshire). Current prop is a 11 x 13/12 (can’t remember), but found a NOS 11 x 9 and will try it out this year.

I suspect that previous post(s) were correct. Unfortunately even for an all-aluminum mini-tritoon, a 35hp (really 30hp) motor is underpowered for this vessel. If I hit 5,000 RPM with a smaller prop, I’ll be looking at upgrading to a 50hp over the winter and entering a whole new world of motors with dual carbs…get ready for some questions about how to work on those babies…peanut gallery!

Thanks again as always.
