I have a 90hp yamaha o/b and the old lower unit went out so i replaced it with another lower unit. the motor starts up turn key just fine but when i put it in forward gear, it'll go forward at a little more than idle speed and it wont go WOT but reverse will go WOT. This one got me. I've tinkered with the cables and everything and tried opening up the the throttles while boat is in gear but nothing. Could it be my lower unit I put in? I feel grey hairs coming out by the minute with this one!! HELP!!
