I'm assuming there are some grease fittings for shaft bearings and such, anyone know where they are located, and what kind of grease should I use?

There is one on the front and rear of the engine crankcase (top). They have rubber nipples over the zerk fitting that you have to remove unless they have already fallen off. The rear greases the intermediate assembly and the front greases the starter. You use marine grease

You do not want to over grease the intermediate assembly since it can force the rubber seal to separate and lead to a leak. I have read that it is better to grease while the assembly is turning which makes sense to me.

Thanks for the info, I thought there had to be a way to grease the shaft bearings somewhere..
