i have an 88' sportcraft 172 fisherman with 1.6 seadrive. when motor is trimmed all the way down upper exhaust ports r under water. how do i get them out. i wouldnt imagine this boat was sold new this way, could there be water hiding in boat somewhere i cant find, or or is it what i read in other post that some or most of the seadrives where installed to low. in which that puts my self bailing holes under water also. water comes in with 2 people at the stern not moving. has anybody seen this problem or have ideas. the exhaust being under water is adding pressure causing motor to only idle at 600 rpm i think it is also causing planing problems. was also wondering if it would hurt to invest in smart tabs. thanx everyone.
