"And Jason, if it is power tilt like Mike said, you cannot use it to trim the motor out, away from the hull, while underway as it is just not strong enough to overcome the push of the prop. And, if you keep laying on the switch and keep the pump in pressure relief, you'll shorten it's life.
But, a technique you can use to find your best trim at speed with one of those is to leave the moter trimmed well too far out and then after you're on plane, trim it in to achieve the best "nose up" trim on the bow. This is where the tilt is working with the power of the prop pushing the boat forward. Then, you can leave it there btween starts and stops until you need to raise it for shallow water.
Of course if you go too far, and the hull flattens out, you will need to slow way down and start over but you will get a feel for how it works and be able to trim up the boat pretty efficiently with a little practice."
