I ended up "throwing parts" at the problem,

New fuel lines
New fuel water seperator
New fuel filters
New fuel pump
New Fuel bulb
New portable fuel tank with fresh gas
new plugs
Replaced 1 CDM Module that was cracked
Checked compression (all 6 cylinders between 115-120)
Cleaned carbs

Finally called a mechanic who said its not the fuel or carbs, but ignition. He ran several tests and said that it was the 2 things, 1st was a vacuum line that had a small split that was causing the low idle stall.
2nd is a bad stator, he said the output was only about 75% of required. Said its needs replaced. I told him to order the parts and he will install.
I will tell you next week how it comes out.

What Foul Hooked said.... Once you get the other issues taken care of you'll be in ship shape and you can keep all the things that you replaced as spares.

If you already haven't, it's probably a good idea to get some Sea Foam and decarb your engines while you are in maintainece mode.

Best of luck.

Thumbs up Re: Possible Bad Gas/Fuel Delivery - Thanks SP

Back on the Water!

After a month of trying everything I could think of, and alot of help from all who commented, my boat is up and running.

Thanks to a Mobile Mechanic!

Went out yesterday and fished along the inlet for about 2 hours, My Merc ran strong, and started immediatly after each drift.

Thanks again for everyones help.

John

Glad you got that straightened out.
I have the same motor with a similar issue, but not to the extent you had.
The replacement of the stator fixed the problem?

Stators are a very common issue with Mercs. I had twins on my Hydrasports a while back and had to replace the stators on both engines. It's basically a set of magnets and windings under the fly wheel. As the flyweel spins the magnets and windings creates the juice you need to feed spark plugs and charge your battery, much like a car alternator.
