Welcome! Need support, you got it. Or share you ideas and experiences.
I just perchased a 16 foot Alaska craft open alum boat for fishing and am trying to adapt my old 35 Evinrude to it. Seems the new boat is a bit deeper than the old and it caviatates at upper end speeds. It would seem that I will have to drop the transom down a few inches or some other adaptation.
Could anyone out there tell me the basic rule for depth that the prop is supposed to be in relation to the keel?
Second question what are the other options for adapting this outboard to my new boat to stop it from cavitating???????
Thanks Tripper Please write me at my email address above
I've had a similar problem on an aluminium cat. Solved it by putting a whale tale on the outbaord and adjusting the trim.
ive always used the general rule that.
A lot depends on the bottom design of the boat, but an aluminum boat, I would recommend starting with the center of the prop shaft at least 5 inches below the bottom of the boat. Trim makes a diiference too as does prop design and condition.
