Been fiddling with getting my engine the right height. Noticed the water, at full speed was up to the second "fin".
Pretty sure it's supposed to go to the lower one and that's about it. Also noticed lots of water spraying off the front of motor. Thought. .."drag".
Raised it up an inch and got more speed.
Got another half inch up and bolted it there. Will see.
This summer I will modify the transom and get another 1.5 inches to play with.
The first and second fin are 3 inches apart.
I'd like to go faster and am maxed out on prop for the model engine I have. 15 hp and 16-40 river jon. I think the boat is just a little heavy and slow. Goes 20 with me, hunting gear, dog, full tank of gas, battery, and 18 decoys. If I could go just a little faster would be sweet.
I don't know why the pics are rotated. They're correct when I load em. Deal wiffit.
