Overall good news. I used some sealant and put the lower back on. It reduced the leak but it was still a little around the bolt. However, from reading other posts, it appears once the lower unit is separated and put back together it's a somewhat common issue.
I got to test it on the lake...
I did a pressure test on the lower unit.
It held right at 12 psi for at least 10 minutes. That seems good. I filled it with gear oil.
I put the right muffs on it and ran it on the hose. It leaked from around one bolt. The video shows the leak. They were all very tight.
I loosened all 4 bolts...
I believe you are correct about that. The O-ring was installed on the lower.
I may have my terminology offer a little bit.
I was referencing the section about the lower unit where the 4 bolts go to bolt it back to the upper motor. There seems to be a large empty space above the lower unit...
I got the lower unit bolted back on and added new gear oil. It starts and goes into forward, idle, and reverse just fine. Technically it's back together properly. But I noticed a bolt that holds the lower unit on seems to have a small jet of water flowing from it. You can see it in the video...
On another note I got some bodywork going on on the bottom of this boat.
I ordered some Marine-Tex and when I added the catalyst it started smoking. Ha! It's some commercial level repair putty. I'm repairing scratches and nicks in the fiberglass. I'm puttying about a 3 ft long section of the V...
Thanks for the follow-up. This info was accurate. I got the seals in and the lower unit put back together. Gonna bolt it back on the boat in the next few days.
I also got the new propeller shaft bearing cage installed. New bearing and new seals all around. I used a little lock-tite on those 2...
Well after looking at this a little further, I may be able to break the ceramic portion off the back of the seal. The shift shaft seal hole is a little bigger on the side that's down deep inside the lower unit. I'll need an extension that's about 10-12 inches, and an appropriately sized socket...
I got my seal kit and removed the shift shaft seal. I'm wondering if there's special tools to install the new shift shaft seal? I used a pick and other flat blade to pull the old one out.
Both sides where the seal go are smaller then the seal. So The seal needs to be squished down to fit...
Well I finally got the two pieces of the foot separated. The nut did not back off the bolt holding the gears in.
Id have to cut that bolt in half and pull it up thru the top. Im not having any issues with the gears. Im going to replace the gaskets I can reach as it is, and put it back...
Thanks for the observations and info. Super helpful to learn that rubber is not something I have to replace. I can just grease the drive shaft splines.
