I got a 1991 Bayliner Capri w/ an outboard 90hp Force. First time boat owner. Bought the boat, the guy said "you have to 'keep on' the trim, the motor will start to fall back down"...and he kept a 2"x8" board under the motor when he had it out of the water to keep the motor from settling back down. i noticed what he meant about keeping on the trim while the boat was in the water. then it got worse. with passengers in the boat, i couldnt get up to speed cause i couldnt trim the motor up? trim, right? but i could trim it up to speed when i was alone in the boat. now it wont go at all. i had the main cylinder rebuilt, no leaks visible...there is an additional cylinder but no lines are connected...anyway the trim/tilt will not keep the motor up and when i get it in water its not able to lift the motor to get going....i'm just a 5000rpm, 10mph, wake makin machine?? is it the pump? ~trim/tilt will raise the motor out of water but motor settles slowly ~no leaks ~rebuilt cylinder ~motor wont lift in water
