Blown trim manual relief valve
 

I installed my new motor for the power trim and tilt on my 1985 Johnson 150. Fill it with fluid and cycled it up and down after bleeding it. A few minutes ago i hit the button and trim tilt fluid comes spraying out the hole where the manual relief valve is on the mount. What will it take to fix this?

I am getting tired of replacing part after part on this motor. All i want to do is go offshore fishing one time this year in my boat. (this boat hasn't been offshore since i bought it back in February, its made one trip inshore fishing and a run around the bay a month ago.) If i can make one trip offshore in it, the motor can blow to hell and back and i wont care. I plan to buy a newer motor this winter.

Sorry about the ranting everyone this motor has been one headache after another since i bought my boat back.

Update: After looking at an exploded diagram i found out there is an o-ring around the valve. I took the keeper out and unscrewed the valve and sure enough the o-ring is missing a 3/8" chunk. Going to o'reillys now to get an o-ring. :sun: Or do i need to use "marine" o-rings? :you:

Actually, for that engine you need the super deluxe, extra tough, extra special synthetic hypalon marine o-rings. (that will be $239.. please pay the cashier up front........ Next please) :you:

One word for you, LUCKY!

I still have a Merc trim unit on the workbench. I have all the parts, but need to make a tool to take the caps off the cylinders to freshen up the insides. I keep putting it off. I know it just goes on the shelf when done. Need to boat more and work on it less

Ridge Runner how about a wrench used to change blades on a side grinder? It may work. Hell it ought to be pretty close.

I'm in the opposite boat. I have the tools, but haven't gotten the parts or pulled mine off to reseal it yet.

The manager at O'Reillys gave me an o-ring. I put it on and screwed the valve into the housing, had to give it a good push to start the threads, and filled it the reservoir with tilt/trim fluid. I hit the t/t-button one time and it started leaking again. Unscrewed the valve again, and now i had TWO o-rings! I looked at my diagram online again, and yep, only one o-ring shown. :head: So i go and sit down with a beer to look at this mess for a while. After looking at the valve i discovered the o-ring O'Reillys gave me was too thick. When i screwed the valve into the housing a sharp edge at the bevel had cut the o-ring into two pieces!

Destroyer, i will take one of those super deluxe, extra tough, extra special synthetic hypalon marine o-rings. :you:

Pic below of the o-ring o'reillys gave me on the valve. Tomorrow i will pick one up at the dealer.

I'm sorry sir, we just sold out. I can order one for you. Should be here in about a month... The factory in China is on strike. Would you like me to put your name on the waiting list? :hide:

No thank you, i just got two at the dealer for $0.99 each. :sun:

:happy: :zip:(fingers crossed) :sun:

I knew it was too good to be true. Got it all buttoned up today, all bolts tightened, ran wires thru the bracket to the moot and connected it. Put the cover back on and hit the t/t button. Nothing.

Upon further investigation, one of my relay connectors has loose connections. I will cut the connector off and put spade connectors on it and call it done. :time:

I found two variations of wrenches over the weekend. I believe they are both from some sort of angle grinder/buffer. Glad you got all buttoned up and working.
