I have 1987 twin 150 yamaha's. The port engine when operating the trim/tilt is a little sluggish to respond. Sounds like it's low on fluid. According the manual i have. They have u putting the engine on the tilt like using the manual release screw. Then pulling the motor cover and filling till fluid comes out. Then removing the fill plug on the other cylinder and fill till fluid comes out.Is this the correct procedure and what type of fluid do i use?
