Was the OD of the caged roller bearing you were using smaller than the Mercury bearing?

I too was going to change from the Dean's caged bearing over to the Merc bearing but the ID's are different. All the machinist I spoke with cautioned me from having the case modified to accept the larger OD Merc Bearing because unless it's in the fixture the drive was originally machined it wont line up perfectly. Now I just replace them every other season to be on the safe side. Bearings are cheap and my time doesn't cost anything.

Also gotta watch out the sleeve isn't too tight on your vertical shaft. It will tighten up the clearance between the shaft and the bearing wearing it out faster and making a lot of heat. I've been told to get my shaft machined and even turn down the race but I've had better luck ordering a few sets of bearings and using the one with the proper clearance. Apparently they're not all created equal.

Thanks. I don't have a lot of time to update the site like I should. So if you don't see something, make sure you call.
