Is there any were on the impeller shaft or bearings that can be greased or needs service, inside or out. I bought this thing new in 91 and it still runs and looks great.. Thanks Frank

Not entirely sure as I've only cut one of those up for another project - but there should be a zerk fitting that pumps grease to the midshaft bearing inside the hull.

look at the rear side of the carburetor intake manifold and see if it attached there (it is on other models) - otherwise look at the midshaft housing and find the hose attached to it.

I am in the process of parting one out right now. It looks like the mid shaft carrier is lubricated by oil from the oil bottle. There is a tube that runs to it from the bottle.
