Contact Tom Thurwhacker, the Merc Guy. I bet he has info on this if nobody chimes in here.

A multimeter is useful when timing when the points will open when your using a timing tool, but here you’re just setting the gap. You just need to be on the high part of the cam.
If you have spark, and assuming there isn’t some other issue, it’s possible that you need to replace the crankshaft seals.

This is a short video installing the seal. Posting it separately so the whole thing doesn’t disappear. I didn’t think to record it but, you should also drop in the “cold” bearing while the bearing retainer is still hot. Remember to put the bearing in your freezer, in a plastic bag (plastic bag is to maintain tranquility – may not be successful in all cases) a few hours ahead of time. https://youtu.be/hvAA1Rn_htg

For some reason, I recall this number…… .235 BTDC…. That is the piston set at .235 before TDC
I “THINK” that is where you set the points to fire.. A long past former member had documentation on these Mercs….
Might have been for the 20H setups but I would think they would be the same..
Someone makes a degree wheel and pointer to set the ignition for these…
Find out who makes that tool and you will be fine… better than guessing….Enjoy that ride….

The seal is under the bearing. You need to remove the bearing first to replace the seal. Heating the bearing retainer expands where the seal and bearing goes. The cool temperature in the freezer will cause the bearing to become smaller. Not necessary for the seal but it wouldn’t hurt anything either. Even though its a minuscule amount its enough that the seal and the cooled bearing will just slip right into the hot bearing retainer. You need to be quick. Once they come in contact with each other, everything starts to reverse.

If you have the “Q” tower, you probably have the high speed gear case?????? I don’t think the impellers are the same as the service lower units..
