Tried to go out twice today - Merc 200 troubleshooting help!
 

Tried to take the Son-in-law & Grandaughter out Friday, had everything ready, weather did not cooperate. Tried again this am. Get to the launch, back in, try to start, grrrr, nope. Knew the one battery was weak, had charged them both Thursday. didn't run it after that because I'd added the oil, but not the gas yet....

No biggie, pull out, tie stuff down, off to the auto parts store, new battery & bam!, back at the launch. Starts up, but rough, doesn't want to idle. Head out the channel & hit it and it doesn't want to go. Seems like a power pack, no power at all but smooth. Pull back to the dock, open it up, look for obvious anything, nope.

Back home, wasn't meant to be.

I can test the power packs while they are on the engine, right? Just dug the manual out.

assuming that's it, what's the best choice as a replacement, used parts, after market, or new Merc? Did this once before, can't remember what I used.

Thanks.

You will need to check spark on all 6

That's what I was going to say too Check for spark,

Truck broke down, ain't that always the way, so boat is on the back burner. Almost positive one side will have spark and the other not, but smart to check first, thanks.

Power pack That's the culprit

I had the same problem years ago only mine would be fine than all of a sudden the rpms would cut in half and the oil alarm would sound, found out the powerlpack the w as wired in with the alarm was the one

Me too, steplift, and that's what I was about to do. although I understand the stator triggers the powerpacks, and could cause the same symptoms, so I'll check that first. I have no problem switching out boxes, but I'm not thrilled with pulling a flywheel off that's been on for 22 years.

Finally got off my butt, no spark on the port side, all three sparking away on the stbd.

So I check the stator resistance at the red/blue wires next to eliminate it, right?

If that passes I buy two more switch boxes, right again?

thanks,

swap the stator wire inputs to the switch boxes from onee side to the other, if the problem moves, its the stator, if it stays the same, its the switch box

Thanks spare, will do tomorrow.
