I will start taking summers off soon and thinking about putting a kicker setup on my 29' Aluminum Chambered Boat for much better range on much less gas. The boat is 8.5' wide, I have twin 225 Yamaha now and on a good day get just under 2 MPG, hope to double to triple that at 6 or 7 knots. Any thoughts, motor size, high trust, extra long shaft? Plan to build a nice setup that can be run from inside the cabin with maybe a TR-1 GPS autopilot. Thanks for any input.
