I have a 89 Bayliner 85 HP L-drive and the motor slowly lowers itself over about 5 minutes. It looks like the fluid for the tilt may be low. Which fluid do I use, I've heard about using 30 weight SAE non-detergent oil...is this just plain automotive 10w30 motor oil like you'd get at canadian tire? The fluid in the resevour looks to be motor oil.<br /><br />Any tips in topping up the fluid.. or bleeding off the pump if needed<br /><br />Thanks
