Gasohol Problem?

: Never saw this TC-W3 stuff. Is it the same as Sea Foam or Mercury's Quick Clean? Who sells it? No. TC-W3 is marine-grade 2-stroke oil you mix in to lubricate 2-stroke crankcases. It doesn't evaporate in the float bowl of the little carbs, so the shellac from the gas that DID evaporate remains in solution with the residual TC-W3 (or any oil that doesn't evaporate for that matter)...instead of forming that really HARD BROWN coating all over the inside to the carb. I use TC-W3 because it's made to burn with gasoline in gasoline engines. I suppose a tiny mix of diesel fuel or vegetable oil would do the same if it weren't concentrated enough to put out the fire or make much smoke. A little top oil is a good thing in 4-stroke engines, anyway....it's why diesel engines just last longer....

@news.verizon.net: Doesn't work with every outboard. My ancient Honda shuts down immediately when unplugged. An indication that it doesn't have a float bowl carb, but a diaphram carb without the float bowl evaporation problem.....a great thing! -- There's amazing intelligence in the Universe.

I believe it is a float bowl, but there's a shut-off switch connected to the hookup.

Gasohol Problem?
I am negotiating the purchase of a sailboat (Pearson 323) with an
Atomic 4. It has been unused for four years, with an unknown amount of gasoline left in the tank. It has been suggested to me that I should have the tank pumped and the gasoline disposed of prior to running the engine. Will some of the oil you suggest prevent the shellac from creating a new problem without pumping the gas? More importantly, this 30-year old engine was not made for gasohol. Should we be mixing some of the oil with every tankful, in addition to filling up at the dock upon each return? I don't expect to go through more than 20 gallons in a summer; will the oil stablize the gas? Best regards, Steve Hayes Readfield, ME |

Will some of the oil you suggest prevent the shellac from creating a new problem without pumping the gas? Yecch....What it needs is to take out the engine and transmission and send it off to a shop for disassembly, inspection and repair/overhaul, if necessary. 4 years unused is a long time for everything inside to rust up, freeze up, seize up, gum up, plug up and every other kind of up you can think of. I wouldn't even turn it over without a real mechanic doing it. 4 years....everything in the carbs is already turned to shellac, the jets are plugged up and even if it does start it's going to run LEAN, too lean for good measure. The carbs should be overhauled and cleaned while they're staring up into the crankcase, making groaning noises and shaking their heads in dismay. The gas in any tank, filters, hoses, valves after 4 years of "letting it go" in a half full tank has gotta GO! Nothing is going to save it. After you get the fuel out, someone needs to look around inside the tank for rust, corrosion, weak welds, gook on the bottom and, please, CHANGE EVERYTHING MADE OF RUBBER...hoses, belts, IMPELLERS, seals, even the vents. If the gas still resembles gas, save it and burn it in your car mixed with new gas 20:1 or so. Took me nearly 3 months to empty my neighbor's 250 gallon oil drum filled with home heating oil poured into my diesel Mercedes. It'll burn so you won't notice any difference. Just add it sparingly to the car or truck gas tank. More importantly, this 30-year old engine was not made for gasohol. Should we be mixing some of the oil with every tankful, in addition to filling up at the dock upon each return? I don't expect to go through more than 20 gallons in a summer; will the oil stablize the gas? I think that's a mistake, too. Engines need to be RUN, especially around corrosives like salt water. This poor guy needs to be run and have an oil change every 10 hours for a couple of hundred hours as he flushes out the crap into the oil pan. I'm sure the mechanic is going to suggest a good top oiling for any primary starting of it, at least I hope so. The "engine tune" decarbonizer/cleaner they spray into the gullets of 2-stroke outboards will help make sure it has some lube in the cylinders, especially those first few minutes. Dump some in the tank, too. The instructions are on the side of the jug. We're trying to prevent scraping rusty cylinder walls with bare metal rings that have no lube film on them....one big GRINDER....yecch. If you already are running it, don't tell us and make us sick. That may do permanent damage to the poor ol' girl. Just cranking it over shouldn't be done before a mechanic has had the heads off to see how much damage has been done to her from just sitting there....rusting away. Of course, now would be a fantastic time to start looking for a low hours YANMAR diesel that's a great improvement, even used....No gas fumes blowing up the family and all that.... |

Gasohol Problem?
The Atomic 4 I had was very similar to my 1947 John Deere M tractor engine,
read SIMPLE & DURABLE. There is nothing to lose by starting it up, put a little oil down each spark plug hole, drain out that OLD gas and go. The carb may leak or overflow, a dangerous thing in a boat. Get a carb rebuild kit from Moyer Marine and spread some newspapers on your kitchen table. It takes about an Hour and the instructions are detailed. The main cause of end of life on these motors is the coking up of the coolant passages from salt water.
