Got the back deck set up now and have had a chance to get out and test the engines and autopilot.
Compared the four blade props to 3 blade Saltwater IIs. Liking the performance on the 3 blades. Excellent cruising speed at 37 MPH, wide open 50 MPH.
My son made a cup and embedded fittings so I can run bait tank in middle and route hoses under the deck. Tested out great.
