"The power Tilt-N-Trim unit on
"The power Tilt-N-Trim unit on my 1977 85HP Johnson outboard was replaced about ten years ago. I was lucky to find an original brand-new one as "new old stock". This past season a problem developed whereby the engine will not stay raised. The unit is not leaking fluid, it raises the engine without any difficulty; but the engine, regardless of the tilt or trim height chosen, manages to creep back down to a fully lowered position. Any thoughts on what, if anything can be done to correct this? I flushed the hydraulic fluid and the fluid level is okay. I've attached a schematic diagram of the unit. Thank you. Mark
