Will low fluid level cause power trim/ tilt go not hold position


Low fluid level will cause it to fail to actuate and not go up or down, can also let it not hold position as well. Filling to proper leevel with specified lubricant is recommended. If you allow the level to go too low, the pump will pull air and could burn out.

We have a 1998 yamaha v4 2 strock 115 engine. we can not get the motor to go down. even if we try to drop it manually


lock lever not down ? does it move up and down at all , the tilt tube could be siezed ,both trim solinoides working ? try standing on the engine gearbox as you trim down or manually release ! if then goes down try injecting the grease nipples with petrol via a grease gun that uses tubes like tooth paste and this will soak the corrosion ! then grease and see if free and if not enough then lift the engine off and remove the tilt tube and clean the sleeves and grease and refit !

How to service a tilt/trim on a 50 hp yamaha outboard. I think the fluid is low as the trim will leak back down after raising the engine.


To check the fluid level, tilt the motor up and engage the tilt lock lever. Open the bolt on top of the tilt/trim reservoir. The fluid should be even with the bottom of the bolt hole. If not add some fluid. When you put the bolt back in, run the trim up and down a few times. That should purge any air out of the system. Always be on the lookout for any leaking hoses or fittings. Hope this helped and best wishes.

I have a 1994 150 hp Yamaha outboard motor with tilt-trim. My motor is stuck in the up tilt position and will not tilt down. It is working when I go up, but not down. I have talked to a used parts dealer...


Stop! Dont replace the pump...I would bet that it is the "down" Solenoid that went haywire. I would begin by replacing the Down solenoid...it is a far easier and cheaper fix and if your pump works to raise the engine then that tells me that it is not faulty. The Down solenoid looks just like a starter solenoid and the one that you are looking to replace has a GREEN wire to it. Yellow with a red stripe is for the starter. Blue wire is the up solenoid. So replace the one with the green wire going to it and I bet it will fix your problem.
