Proper shaft length

[ouzo]

I just bought a 12 ft. used aluminium boat and I need to know how far below the water the prop should be. I just joined the forum the other day and I am enjoying the threads immensly. Thanks to all the knowleable people out there for your helpfull info.

Re: Proper shaft length

The cavitation plate of the engine needs to be somewhere from 1" below the transom to 2" above the transom. The exact spot is determined through trial and error.
