I have a 15' Cherokee Aluminum boat with a 1972, 50 HP Mercury outboard motor. The boat has been outfitted with a 12 gallon fuel tank in the bow. I have put two batteries in the rear of the boat. Between the seats, decking and other weight in the boat, it sits fairly level in the water, but slightly tipped to the rear (and slightly tipped to the batteries side).<br /><br />The motor does not have power trim, so it remains in a fixed position, regardless of speed. The transom has about 22 degrees of angle. The current setting has the motor fairly level, but the PROP is slightly tilted in, about 2 degrees. (see link below for a rough sketch of this setting)<br /><br />I have 1 more setting on the motor that would allow me to exaggerate the scenario mentioned above, or I have 5 more settings that would allow me to tilt the PROP out more.<br /><br />At full throttle I currently get about 20 - 25 miles per hour (according to GPS). We troll and ski with the boat.<br /><br />What differences in performance might I hope to gain or lose if I tip the motor one way or another when trolling?<br />What differences in performance might I hope to gain or lose if I tip the motor one way or another when skiing?<br /><br />You can see a very rough sketch of the current setting at this site: http://www.structuredwiresystems.com/other/BOATMOTO.jpg <br /><br />Thanks
