Dirtiest Filter I have ever seen in my life....

200 feet from the lift? here's a tip: When your engine is spitting flames from the carburetor, TURN IT OFF.

Just glad mine wasn't doing that when I was running back to the dock with gasoline spewing into my bilge

Not sure how that would have gotten from there into the oil, but I'm not a certified mechanic.

I do agree that he needs to do a complete fluid change because it's obvious the boat was not well maintained. I'd change out plugs, wires and distributor cap/rotor while I'm at it.

The engine ingests the stuff through the intake, it gets caught in the combustion chamber, partially burned, and the ash deposits on the piston, rings, cylinder head, and cylinder walls. As the engine operates, the ash is scraped off the cylinder wall, scoring the surface (both up and down). As this happens, metal from the cylinder wall or sleeve is taken along with it. The mixture is then compacted on the top of the piston and/or the cylinder head (around where the spark plug comes in). The charred remains of what is probably rubber ash and straight carbon breaks off inside the cylinder and is either pushed out the exhaust (scraping against your valves and valve seats) or gets caught under the rings (since the cylinder wall is now scored), and is flushed into the crankcase (thus the oil supply).

thats exactly why boats have USCG-approved flame arrestors or spark arrestors.

Makes sense.

lack of air = rich condition so I bet it was backfireing out the exhaust

[ddmracing05]

it was alittle both

[ddmracing05]

does anyone else see the problem with him running the engine with all that crap in the intake (not to mention w/o the spark/flame arrestor)?

I'll bet all that crap found its way into your oil... better change that and your oil filter ASAP. As in tomOrrow.

regardless, I sense a top-end rebuild coming up in the near future.

Actually its been running fine ever since I cleaned that, and some other stuff in the intake. And ive gotten an extra 4 mph out of it . But its running better than ever now so im not worried about anything.

When you turn it off and flame comes out at the right time... There will be no suction going into the engine to suck the flames back it. If i were to shut it off the flames would probably keep comming out.

you do realize some Bildge pumps create a spark when you turn it on? lol. There was a guy in the keys that accadently put the fuel nozzel in his fishing rod holder (of course off shore fishing boat) after awhile he realizes all that fuel just went into the bottom of his boat. So, He just decides to turn the bidge pump. lets say the Fire department had a talk with him.

Im just wondering but do you know how to use the multi quote feature?

[Ruune]

you do it manually.

That's why it was totally submerged when it turned on. Gasoline floats, so I figured I was somewhat safer.
