BTW, the trim tab needs to be adjusted to offset the steering torque

That my friend makes a lot of sound advice. The boat does have some big a** trim tabs.
I guess you use them when travelling in a straight line, right? Turning with the tabs lower in the water wouldmake it more difficult, correct?

I replaced the engine myself last year and a friend said that I should have it sent in for exact alignment.

One other thing... there is a tab above the prop which has very much disintigrated. How important is this part?

BTW, thanks for your quick advice.

That's the one he's talkin about, it helps equalize the steering torque. If it's a right hand rotation it may be turned slightly starboard to help reduce steering pull, if left handed to port.

Some people want a boat to pull toward a circle when the steering is released, you will have to adjust it to your needs.

You can get the steering zinc at any boat store they all have them.

My 1975 V20 Cuddy 165 I/O used a 17 pitch when I got it, but I liked a 15 1/4 X 15 much better for over all use, got up on plane in just a few seconds.

that is the one I was talking about. the straight 6 drives used a bigger one than the regular tab, it might be a little harder to find, but go with the big one if you can find it

here it is....
