The engine is a 20hp Tohatsu that's hanging off the stern of our boat. It's about 30 degrees here. I figure it will take some time for the internal engine parts to get hot.

Gratuitous winter picture of the outboard

Plan B is to lift it off the pushpit and let it hang into the water off one of the davits. At 117 pounds, it's not something I like to do too often if I can avoid it.

Plan C is to get the ear-muff looking device to clamp on the water intake and run the engine for longer periods of time. It's not easy to find flowing water here though. I'd probably hook it up to our washdown pump when the temp get's above 32.

After last winter, when it was run completely out of fuel and stored in our warm furnace room, it took the whole summer to run right again. I'm looking to avoid that by running it periodically throughout the winter.

So will it hurt the engine to run it for 30 seconds without water???


While the engine may remain cool due to the temps, the impellor in your water-pump won't be too happy. Why not pull your plugs and spray fogging oil into the cyclinders and then give the starting line a few tugs. Absent plugs, the engine will turn over easily distributing the oil on the cyclinder walls then reinstall the plugs. On that motor you should also be able to pull the fuel bowl quite easily. Just dump it out and wipe it dry with a lint-free cloth.
