I don't know why they mount those motors so high. Recently bought the 1654 Sportsman with the 30 hp Mercury and was having terrible cavitation problems at anything more than half throttle. So bad that the alarm would go off on the motor and send it into limp mode. Lowered the motor all the way and it's still doing it. No clue what to do other than a Jack plate. Hopefully the motor isn't messed up now after it happening multiple times. I like the boat and the way it a set up, but I do not like the Mercury and the way they have them set up.
