New owner 88 Comp. Love it and want to fix all the little problems..IE fuel gauge bouncing and inaccurate....steering cable issue.. But, Most of all at about 20-24 MPH I have just started to hear a slight whine.. Could be my imagination...It stops when I throttle down or speed up.. Has any one experienced this and is it something that could lead to other problems. I pulled the boat out of the water and checked the tranny fluid while on the trailer.. Nice and red and full cold??HELP
