Plugs a little milky

Curapa · #1 04-15-2011, 05:56 PM

Took the boat out today after replacing the power pack. It has run flawlessly in the yard.

It ran perfect for a few minutes, I went back to pick my buddy up that was parking the truck and it shut off.

It acted as if it was not getting fuel. I had not tools with me so the best I could do was make sure the fuel pump was pumping, it was.

I got it back to the dock by holding in the choke and applying throttle gently.

I just checked the plugs and they are a little milky. A friend borrowed my comp gauge so it will be tomorrow before I can check.

Any thoughts on the matter in the meantime?

White, clear or brown milk might be fuel contaminant or head gasket leak.

are you running the fuel through a water seperator? if so pump some in a clear container and see if it looks ok.

Got up this morning and I still don't have my comp gauge so I went ahead and took apart the carbs, guess what? Water in the bowls.

I am beginning the draining process now.

Worst case scenario would be water entering cylinders thru crack in crankcase....so the hope is some water in the fuel...hope it works out in your favor...

There was about 3/4 gallon of water in the tank. The Fuel sending unit gasket was bad and letting water in. The boat has been sitting for a few months and it has rained ALOT here. I believe water leaks through the access right above the tank so I will be replacing it with a new access deck plate.

I cleaned the carbs,

I disconnected the fuel hose from the engine to use the fuel bulb to pump fuel through until there was no water,

Replaced the separator with a new one.

The boat runs great again. I have checked the water separator several times and there has been no more water in it. I still do not have my comp gauge and I really want to check it to make sure there was no damage done to my cylinders. I let the boat idle in the yard for almost an hour and there wasn't even the slightest hiccup.
