Mike,
I finally was able to get the boat on the water and didn't have much of a load on it. It ran great and maneuvered well. Fuel mileage was very good. There was just two of us and all the safety equipment and light supplies. I was doing the break in on the motor and running WOT less than a minute as provided in the motor manual. The WOT speed was only 40-42 MPH. What type of speed are you getting from the hustler 4blade 13.5x15?
The only thing I noticed was that the trim gauge didn't seem very accurate. It seemed like the gauge always showed it was down even when I was raising it. It would eventually show it was in the raised position, but didn't seem to be very accurate with the position of the trim in comparison to what it was showing on the gauge. Gonna contact the dealer and see if they can take a look at it. Thanks again, Bob
