Just curious, Jet - what kind of pump is it? I have a guess that it might be a Dominator. I have the slightly older Dominator pump, and it does not use grease at all. The rear bearing is water lubricated. I have been told that it doesn't really matter whether the rear bearing is water, oil, or grease lubed. Somewhere on the web is a rating for the bowl bearing, showing dry, water, oil, and grease rpm ratings.
How do you like the new 496 engine? I assume it's Fuel Injected. How many HP are they rated, and what kind of speed numbers are you seeing? Also what kind of hull?
