    Have you looked at the jet pump sections in my signature links?

    K447's links were very helpful. Remember that the MSX shaft will remain in the hull, and will need a special tool for removal if you would like to change the through hull bearing and seals. If you're going to the trouble to replace the pump bearings, changing the through hull bearing and seals is only a small bit of extra work with the right tools.

    Thanks! Thru Hull bearing was bad anyway so I replaced everything! Quite a project!
