Re: Trim ???
Smokyforce, as a new boater myself, perhaps I can offer an explanation without a lot of technical stuff. The prop on your motor will always try to run parallel with the surface of the water. If you trim the prop in or down, it will push more of the front end of the boat into the water. If you trim the prop out or up, it will push the front end of the boat out of the water. Trimed all the way down, more of the boat's bottom is in the water, and therefore more friction and less top end speed. As you trim up it raises more and more of the front of the boat out of the water and therefore less water friction resulting in faster speeds. If you continue to trim up you will reach a point where you'll get cavitation (prop comes out of the water, or churn air) in which case you lose speed, and can potentially over rev the engine. Somewhere between trim up and trim down is a sweet spot that will give you maximum speed at maximum RPM (usually somewhere around 4500 -5500). And at any RPM you can play with the trim to achieve the highest MPH. Hope this helps, and that someone with more experience will add or correct.
