Fletch,

The bearing came off pretty easy.  It was a little stuck, but not too much trouble.  We kind of had a "Aha" moment when we realized we could just drop the aft end of the shaft enough to slide the bearing off without disturbing any of the gear spacing.  We never took anything out of the drive except the bearing. When I saw that was possible, I was like "hey don't move a thing" lets just sneak it off there and put the new one on.  I have a lot of respect for your info regarding not letting things roll around on the dock.  Smile

The old bearing was not identical to the new bearing, which is a little scary.  Similar but not exact.  I know the one I put on came from Crinmar because it was in original Bukh/Crinmar packaging, so maybe the old one was an adaption...or just from a different period in time.  

You and Bill have been so helpful with this process.  I really appreciate it.

Regarding the sail drive rear seal and bearing assembly, I think you have 2 choices. One is to change the whole assembly if it shows damage due to electrolysis, or just change the seal. The seal is a bit of an odd duck, but is obtainable. It is a 17x30x9 and is a double seal. These are available in the open market but not easy to find. Somewhere I have the information on the exact name and info on the seal and will look for it and then post again. Your best current source for Bukh parts is LSM-Diesel, and write to, or speak with Erik who is very helpful and does speak English. They have a catalog on their website and you can order parts from them. For communication with them use info@lsm-diesel.dk. One issue with them is that while their parts prices are very favourable, they will charge a minimum shipment fee of something like $54, so it is better to line up other spares you may need, or check with other Laser owners to find what spares they require, and do a combined order. A seal should only cost something like $10 in the market, so try not to pay $54 to have it shipped.

When I first ran into the problem, and on mine the entire rear bearing and seal assembly was eaten away by electrolysis, I made a new one. I could not find the double seal at the time and so I had to purchase 2 pieces of 17x30x5mm, and then mount them back to back. If you try to do that on the original assembly, owing to the two seals combining to make a total of 10mm thick instead of 9mm, you will not be able to fit the spring keeper on the back of the unit together with its thin washer that is meant to go in front of it. In my case, I machined an entirely new rear bearing and seal assembly and allowed the extra milimeter of recess in the back in order to accommodate the twin seals and the retaining keeper (circlip). However, if you are operating in a fresh water environment, then your assembly body is probably all good and you just need to change the seal.

I will get back to you with information on the open market seal when I find it.

Found it. Go to amazon.ca and search for Oil Seal 34665013 by Tohatsu. It will show up an Amazon as Oil Seal Case 346-65013 Fil Tohatsu Nissan outboard 9.9HP, blah, blah, blah. Price is $5.35.00.

And a "thank you" to our late friend who shared this info with me.

Cheers,
Frank
