[QUOTE="Natedog57, post: 360452, member: 14790"] Regarding motor height... I think you're very close to where you need to be. I'd try adding a 1" - 1.5" spacer (over the transom, under engine bracket) to raise the cav plate slightly above the bottom of the hull. I've been able to have the cav plate 1.5" above the hull, then on another boat that was to high, it needed to be "in line" like yours is now. Regarding trim settings... the farther back raises bow running height, and moving forward(closer to the transom) lowers the bow. I always tried to set my motors up so the bow might porpoise slightly with a very light load, but then be fine with a heavy load... or you can change settings depending on how you're going to run the boat on any given day. Generally speaking, farther back will take longer to plane, but have better top end speed (as long as it doesn't porpoise). With all the batteries you have I don't think you'll have issues with porpoising, I'm guessing that if it's too far back it will just be very slow to plane out. Congrats on that Merc, I've got one and it's a sweet little motor. [/QUOTE]
