Timing and Synchronization of 1982 Merc 200 Outboard

[tecoon]

Hi,

Anyone have any tips on timing and synchronization? Or anyone know someone in the Southern NY/Southern CT area that I could pay to do this work?

I have called around and stopped by a few different marinas that work on Mercs and none of the service guys I spoke with even seemed to know what a dial indicator is...so I wasn't too confident about letting them do the job.

I don't have a dial indicator or a timing light but I could buy both and attempt to do this job myself. I have the manual that has the step by step procedures and the proper adjustments/settings.

The motor took a dip in the water when it was on my old Glastron so I had to rebuild the starter, replace the rectifier, internal switch boxes, and an ignition coil. Now I have the motor on my V20 and it runs but when I give it throttle it either stalls out or shoots up to 4000 rpms when it should only be at about 2500. Even when I am trying to cruise at 3000 or so, the thing speeds up and slows down on it's own without me even touching the throttle. The manual says any time electrical parts are replaced, the timing and sync must be rechecked/reset.

Any chance that I won't need the dial indicator and I could just go with the timing light? Or could the problem be something other than the timing? Compression is good, sparks are all good, fuel seems to flow well, new gas, new fuel/water separator.

Any help would be appreciated.

Thanks,

David
