Well, theoretically, the farther you can trim the engine “out”, the better the rig will perform because you are getting more of the hull out of the water and reducing drag. But, there are several factors that affect this theory. Trim it too far out, and the engine will just ventilate at high speeds. Or, perhaps trrimming too far out will cause the boat to “porpoise” . Depending on the rig, trimming too far out may cause the boat to be hard to plane because the engine is push the bow up while trying to plane the boat off. The boat will plane off easier at lower trim settings. So, you may need different settings for different situations. It all comes down to trial and error.
