When we get mail on boat-handling problems, the bulk of it sounds like this: "When I do this, my boat does that and I can't make it stop." Sometimes the problems are mechanical and sometimes, well, they're just operator error and as easy to correct as pushing a button — literally. This is how properly trimming an engine's outdrive can eliminate pounding, porpoising, wandering and sluggish speeds.
Problem: My boat pounds into the waves, often taking water over the bow.
Cause: You could just be going too fast in rough water, or the propeller might be trimmed too low, driving the stern up and the bow down.
Solution: It's possible your hull has developed a "hook" or a concave bottom that causes the bow to ride low, but more than likely, your trim is out of adjustment. Start by pulling your trim tabs up fully (if you have tabs). Then trim the propeller up with the trim switch on the gear shift/throttle. Do it a little at a time until the ride improves.
Problem: My boat leans to the left at planing speed but is level at rest.
Cause: Prop torque (the twisting force that the prop creates as it turns in the water) can cause your boat
Solution: Adjusting your trim upward will often correct this issue. In the short term, adjusting your crew to counterbalance the force can be helpful. The best solution might be to add trim tabs to your boat if you don't have them, and adjust them to level the load. Visit bennetttrimtabs.com
Problem: I trimmed my engine, but the boat still pounds the waves too much.
Cause: V-bottom boats usually have a very sharp stem — the point of the bow — to slice the waves. The bow might still be riding too high to cut the chop.
Solution: If you have adjusted your prop trim, chances are that your trim tabs (if you have them) are not properly adjusted. Or, you simply might be going too fast for the water conditions. Slow down, check your prop trim, then start putting the tabs down gradually with one-second taps to the control buttons. Experiment to find the optimum ride.
