As some of you might know, when I returned home a couple of weeks ago from a vacation at the lake, my lower unit started leaking fluid on the garage floor.
I have since drained the lower unit oil and it was milky. It was leaking fluid in and out....
Yesterday I removed the "Prop Shaft Carrier Housing" from my 1985 Evinrude 150.
The job was fairly simple so far and I got a little lucky.
1. Removed the prop.
2. Removed the 4 bolts with seals that held in the housing.
3. Removed the housing from the lower unit. This is where I got lucky as many times a puller is needed although the only thing holding this in is one large O-ring. I could not remove the carrier by pulling on. So, I pried a little on one side with a screwdriver and saw the housing move slightly. I then pried on the other side and it popped right out.
4. Removed the large O-ring from around one end of the carrier.
5. All I need to do now is remove the 2 prop shaft seals. I don't have a seal puller so I will be looking around on Monday to see where I can beg, borrow, rent, or buy one...
In the photo below, you can see the parts lined up. I will post more photos once I get the seals out. The only things that stops the housing from leaking fluid is, the O-ring, the 4 bolts with seals under the heads, and the 2 prop shaft seals.
I received the parts from my mechanic/dealer yesterday and will post a photo of those also.
The parts were $41 including shipping.
When I am all finished, I will post these into an article.
Do you run fresh water only? Tried to pull apart a friend's '89 Yamaha 90 HP last year and it was quite frozen, even the marine repair tech had some difficulty disassembling with the proper tools and skills, but this is also a salt water motor. Glad it's going smoothly for you!
I do run in mostly fresh water but I also run a lot in brackish water where the rivers meet the ocean. I rarely run in straight salt water very long so that is probably why it came apart so easily.
This is the first time I had to do this on this motor so I had no idea what I was in for.
I do feel fortunate that it came apart so easily
