Re: Mark 20 won’t spin freely

quote ronboonville:

gear case off and that’s where the problem is. The retainer behind the prop is left hand threads, right? I’ll need to make a spanner of some type and also for the impeller.

These can be made fairly easily. Do not be tempted to use a punch, as I have had to deal with several motors that had that treatment and it really does not work. I have a block of steel with a hole drilled through the center that allows the prop shaft and drive shaft to slip through. I then have several different series of holes drilled into the block that I put roll pins in that fit into the holes in the nuts. I use a pipe wrench on the block, and it works fine. I have a set of holes in it for the water pump, the prop shaft, and the K series lower units. I have used it on all of them.
