Re: Mark 28 issues

quote JasonH:

The crankcase on the early to mid 60s are prone to leaking. I have been through at least 7 or so 60-65 Merc 200s and they all leaked on fuel pump side where crankcase halves meet. There is a fairly long span between bolts in that area which mercury eventually changed. There is a blank (not drilled) boss on the early motors that I have thought about drilling and tapping then using.

As far as the rope staying with mag: Yes there is a little notch in crown for knot, DONT use it! The rope knot doesn’t seem to release well with this design. I had one start and swing the big wooden handle around like a medieval ball and chain, at least it felt that way. Don’t ask how I know all this. Probably others out there who can also say they have had a beat down by one of these.

Good information Jason! Perhaps I have been lucky with my cases. Although I rebuild all of them first, perhaps I have corrected the leak without even knowing it. As for the rope getting stuck in the notch! I almost had that happen myself. I didn’t have the wood handle on mine though! Yikes!
