I have a 2007 2 stroke Merc 50 on my 16 foot Triton.
Since I use the boat a lot in mud and sand, I change my water pump at least once a year, whether it needs it or not.
When I had the lower unit off the motor today, I noted that the bearing/seal cone where the driveshaft goes into the gearcase, had some corrosion. I can look at it and tell that it is going to have to be replaced at some point.
I had the same problem on a 2005 25HP merc, but I got rid of the engine before I had to replace this part. So, I've never replaced one of these pieces before. Looking at a parts diagram, it looks like it's a simple press fit. Is there a way to remove it without having to take the driveshaft out or disassemble the gearcase? Or is it more involved?
