I got an older 16 hp go devil. I put a tach on it ow 4050 in the water with load 3150. Now is the boat overloaded do I need to lighten the load. Or would a bigger boat Ie displace more do the same thing? I would like to run about 36 to 3800

What size prop are you running? Website shows it should be a 9x3.

There is not a "one size fits all" when it comes to props, so you have to buy it according to what your loads are most of the time.

My 16 gdlt on a 1436 boat would run 14mph alone and 12mph with me and a buddy.

I bought whatever godevil recommended. I think 9x3.

I have a 16hp godevil and I'm gettin about 3300 rpms in the water and that seems to be doing me pretty good. but then again I'm running a 9x5 prop instead of a 9x3, but its worn down probably 3/4 inch so it will be needing to be replaced soon. anywho. hope this helps.

bbb what do you think the rpm's om that 27hp were , and what kind of boat did you have it on?

Both my kohlers, 25 and 27, were right around 3700 when running the fastest.



Best speed I ever ran on the gps was 19.2 in the river.

With the current

This part of the river is too close to the lake to have much current. Usually my speeds up river are <.5 of what my speeds are down river.
