I have a 1999 Johnson 50 2-stroke. The engine slowly leaks down when trimmed up. I think the manual release valve is bad. If I pull it out will t/t fluid come out? Can I buy o-rings for it and what size? Thanks.
Anytime I worked with hydraulics it got messy... : Here's your part numbers, now you need to shop for best price. http://www.crowleymarine.com/johnson-evinrude/parts/53493.cfm
So, I removed the valve and saw that the seal on the valve towards the rear was broken. This seal is the smallest of them in the valve assembly. I called my local marine shops and none of them had the seal. I went to Lowes Home store and started poking around the plumbing department. In the faucet/sink repair area I found a multipack of seals that looked suspiciously familiar. Took it home and wouldnt you know, one of them fit perfectly. Looks like a dead match. At $1.62 for the pack it was a good deal, considering the OMC version was $2.26. Everything works now...except that my rack steering is frozen. Its always something.
