Recently I reported we had permanently removed our 9.9 HP auxiliary motor. I now believe that the combination of the heavier Honda 115 HP main and auxiliary motors makes the Marinaut 215 stern heavy, preventing our boat from keeping her bow down in heavy seas. What a positive difference it made! We recently we got into 3í to 4í head seas, and had no issue keeping the bow down. She cut right through the waves with mostly full engine trim. Our friendís boat did not have our problem, because they have a Permatrim hydrofoil. However, they get 25%-30% less mileage. The reason for the mileage difference, I think (any other explanations are welcomed), is that the more oneís boat is stern-heavy, the more energy is required to create the lift needed to bring the boat to level trim. This brings to mind several things stated by others in the past. Dr. Bob could not understand why we had so much problem in heavy seas in LI Sound. He was right in that his boat would not have had similar issues. Fellow C-Brats were right about Permatrim, but Les Lampman was right, too, in saying that the boat did not need it ó provided of course that it is not stern heavy. If I were to do this all over again, I would use a 100 pound lighter engine (like a Suzuki) rather than that big 150 HP block Honda 115, if I wanted an auxiliary motor. Otherwise, I would go with the Honda 115, which is a low-rpm, high-torque and more fuel efficient motor that gets in excess of 4.5 mpg. Anyway, thatís my take after using our boat for 9 seasons.

When I bought my 16' C-Dory, it had a 50hp Evinrude as a main motor and a 6hp Evenrude kicker. The kicker is mounted on the helm side, making the boat trim to starboard when I use it alone. Sad
I have often thought about either moving the 6hp to the port side, or eliminating it altogether. My solution was just to use the 80qt. ice chest I use for a, "Catch-all, extra seat, fish box as a movable ballast and trim the boat with it, when I'm out by myself. Thumbs Up
