2002 YAMAHA 4 STROKE 100hp

[aquajohn]

I had trouble witerizing this new engine. Had to take off wiring clamps. air intake cowling and covers just to fog the carbs. Does anyone know want I'm in for in attempting to do the periodic maintenance myself. Is it worth the headache. Working with a dealer is a headache of another kind

AquaJohn,<br /><br />That is a very expensive motor you are servicing. I suggest that you find a good dealer in your area. We are in the finger lakes region and try not to make it a pain for the customer. I know what you are saying because they become our new customers. silverlakemarine.com

I don't think winterizing the F100 4-stroke requires fogging (and removal of those items).<br /><br />The owner's manual for all my Yamaha 4-strokes suggest running the carbs dry, and removing the spark plugs and putting a teaspoon of oil in each cylinder. No mention of fogging. Of course flushing with fresh water and stabilizing the fuel is a must. This has always worked for me.<br /><br />Just follow your owner's manual....its very easy and much less expensive than taking it to a dealer.

The engine mfgs do make a foam type oil spray for storage, you would remove the spark plugs and spray inside. I have done both ways on fuel in the carb. I use to drain mine then I figured that the fuel you run through the system has stablilizer, why drain the carbs and run the risk of drying out the seals/gaskets. I haven't had any problem doing it this way.I keep a Honda generator w/gas for emergencies and I haven't had any problems. I did leave gas w/o stablizer in a small generator for about 7-8 months and that was a mess and required a severe soaking and cleaning. Just my 2 cents.<br /> I do have a 9.9 Evenrude in long time storage, that does not have any fuel in it and it is fogged with the spray foam about every 6 months when I don't use it.

"why drain the carbs and run the risk of drying out the seals/gaskets"<br /><br />The seals and gaskets of toaday's modern 4-strokes don't easily crack and rot as a result of being dry. Much of that is myth based on past problems with older outboards, older gasket materials, and old fuel technologies. <br /><br />Also, even if the fuel is stabilized, much of it still evaporates in the carb bowl. Otherwise you wouldn't need to prime, and choke for that first start of the season. <br /><br />Running the system dry not only empties the carbs, but also the fuel lines, fuel filter, and fuel pump.<br /><br />If you've got a method that works for you, then great. But I figure Yamaha knows what they are doing by recommending running them dry.
