Hello everyone, I have a 1992 Yamaha 40 MSHQ. I bought the boat and outboard for a project 3 years ago. Got the motor running carburetors etc. Just finished a rebuild phase on the boat so I could do some fishing.
Everything has been great. Able to count on the outboard and really liking the way I put the boat together. Meanwhile keeping up with all the preventative maintenance which I’m adamant about.
Today I cleaned the power head and detailed it. It needed to be flushed also. So I ran it in a big drum I’ve cut down to size. It gets way better water pressure than with muffs and I keep the fw hose continuously running keeping fresh water in the barrel. So I ran it about 5-10 minutes. Never any longer. I use the boat in freshwater only by the way.
After removing the drum I was wiping it down and saw what’s in the picture here. It was late so I’ll pull the prop tomorrow but I’m pretty sure my seals behind the prop are gone.
Ill know for sure after pulling the prop and draining the gear case. I just changed it a month ago and always use new OEM gaskets on the top and bottom plugs.
Can someone give me an opinion because it looks more like mud than oil with water in it? It’s coming from between the prop and case.
Once again I’ll be entering new territory changing out the seals. I would greatly appreciate any knowledge shared that may help me. I’m wanting to get it done and get back on the water.
We are having a church picnic at the lake this weekend and I’m supposed to give boat rides.
