That is a classic sign of a saltwater spray or water condensation buidup issue. Any time you are dealing with a powerplant issue on a boat, the prudent thing is to take ti to a mechanic. A vessel underway at sea without power represents a serious danger and can become a real emergency very quickly.

While I still believe it is almost certainly an issue with water that has mades its way into the controls I would not attempt to repair this problem without first running it by your local mechanic.

Good luck.

Looking to repower 1997 Four Winns bowrider with newer outboard engine. What max HP is boat rated for? Found Yamaha 150 XB 2016 for a good price . Will boat work with a 25 inch shaft? Thanks,Kathy


there should be a manufacturers plate attached to the hull of the boat with a number of passengers it can carry and the max hp motor allowed to be fitted
talk with boat shops as they will know the approximate hp for each make of boat and length
while it may be attractive to fit big hp motors to small boats , it in fact makes the boat less sea worthy and makes capsizing easier so get the advice right from the boat shops

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 !

I have a 2008 25 hp Mercury 4 stroke outboard. Will the manual tilt assist you offer work with this motor without needing to modify the lever?


I have one of these tilters and it's on a 2009 25Merc. I had to modify it because the pull handle is located lower on the back of motor.

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.
