I have a 1987 20ft starcraft, with a 110 hp johnson. When I get the boat up on a plane it seems like the boat is still setting to deep in the water, over 3/4 of the boat is still in the water, the spray from the boat starts up around the windshield, on a windy day the spray will get me at the steering wheel. The cavatation plate on the motor is about even with the bottom of the boat, but I'm wondering if the motor is set right or if I should try adding Jack Plates and try playing with it. Has anybody had this problem?
