"i have a 40hp 1986 evinrude.

"i have a 40hp 1986 evinrude. i have a question regarding the tilt. when i tilt the motor up to go in very shallow water, it slowly goes back down again even when i drive slow, is this normal or should it stay up when I'm driving slow? the tilt is mounted on the starboard side of the motor. there are no oil leaks around it, maybe it needs topping up. can anybody advise me on this. and also if it needs refilling what is the procedure. your help is appreciated

thanking you in advance
Tony"
 
"Its sounds like the piston is

"Its sounds like the piston isn't holding pressure. Check the level of fluid and top off if necessary, see how that works."
 
thank you for that but what so

thank you for that but what sort of oil do i use and do i fill it till it starts to flow out of the filler hole
cheers tony
 
Use ATF Dextron 11 or omc trim

Use ATF Dextron 11 or omc trim and tilt oil
Fill until oil runs out the fill bung hole
The tilt unit you have was never very strong and would not hold if you went above idle in gear
