200HP Johnson, 1987. Lower unit broke shaft Labor Day (other post regarding shift rod length)

Got another one, used the old pump (new last fall) and installed unit.

Tried to start it...just tries to catch on one, maybe 2 cyls. Does not start. Probably not plugs, but put 6 new ones in anyway.....no go still.

Inductive timing light shows I have fire going down the plug wires to the plugs. Main fuse is not blown. (The hits on 1 or 2 plugs told me that I guess.)

Bulb pumps up good. Small filter under cowl is full of fuel when I unscrew it.

Disconnected the linkage to insure the shift rod is not throwing off the rev/fwd/start position. Moved throttle lever manually, still no go.

Any other thoughts to steer me in a direction? I am thinking that the pump is unrelated and this is a different problem, coincidently showing up now. I have the batt charging tonight to test again in AM.

Thanks for any and all help, Greg

I answered over on marineengine.com with a possibility.

What shaft and what caused it to break ?? Did you hit something, run aground ??
Water pump will have no bearing on it starting as far as I know. Sounds like a timing issue. You say you have fire going to the plugs, however is it going there at the correct time ??
