Hey guys,
I have 2006 twin 350 Mag Horizon closed cooled (OW360139). I recently had a no start issue that I believe I may have solved by replacement of the fuel water separator. The engine would not start 5 minutes after it was already running but has started both times since.
My question is what are the symptoms of the notorious cool fuel module failure. I know my boat had them replaced 6 years ago by the dealer right before I bought it due to failure. My fear is that in my troubleshooting I have realized that my spark plugs are quite blackened and I have a decent smell of fuel in the engine bay when the engines are running at the slip.
As I understand it, smell of fuel (due to high fuel pressure) and blackened spark plugs are a ky sign. Is this accurate? and is there anything else I can look for. I don't own a fuel pressure gauge but am not opposed to buying one if it would greatly help. Through a friend I do have access to that diacom / Rinda / mercruiser computer program where you can hook up to your engines ECM.
Any thoughts? I would like to avoid the cool fuel failure and its further result of getting to the fuel injectors.
Thx
Brian
