DaveR, thanks for your recommendations....
FYI, after towed to dock, engine would 'turn-over' OK, but not start. I will try external tank to rule out, but would have to run at
least 15 minutes at half-throttle to rule out gas issue to simulate current behaviour senario.
Also, you indicated the coil was on the back of engine... I don't have Service Manual available, is it behind the black cover per
chance ? Sounds like if the coild has to be reaplced, the hard part, will be locating one, w/o a special order from marina.
Parts like this, I'd rather oder through a marina than mail-order, in case wrong part is ordered or received

As always, thanks for everyone's feedback, greatly apprecaited !

IIRC, the coils and the power pack (ignition module) are all on the back and I'm reasonably certain the black cover has to come off to check them. If it is turning over and not starting, check for spark on all 4 cylinders first. The power packs on those do eventually fail and your might be dead if all 4 plugs are not firing. I know of no way to test the power pack itself, you basically have to eliminate the generator coils (you need a peak holding DVM like a Fluke 87), and the optical sensor (you need an oscilloscope) CDI makes a power pack for that motor that costs less than the OEM and it's probably more reliable.
