Thread: New Boat and good fishing

The dealer bolted the motor on in its lowest position. I am going to raise it one hole and bend the trim tabs down and give that a try. It is close but I think it can be better.... On some things I think I have OCD

On the bolt holes, ideally you want the top of the cavitation plate running level with the bottom of the keel. Check it with the motor tilted/trimmed down. I would check it before raising bolt holes. Most folks set up the motors that way.

Think of porpoising as the hull falling off of and then returning to a position of riding on its rear pad. Trim tabs and foils can help. Weight distribution is also a big player. This is one reason the batteries on a bass boat are located at the rear. Sometimes a boat is going to porpoise at a certain RPM and you just have to trim through it or raise speed past that point. Kind of like a harmonic. More power/thrust is often a cure as well.
