I'm preparing to put my 2019 AR210 away for the winter (up on a boat lift). I've read a bunch on this forum about fogging, but I'm still unsure exactly how to do it on my boat. I gather the TR-1 is a relatively new engine, and I haven't found any details on this forum for fogging this particular engine.
I have the pdf service manual for this boat (which is also the manual for the various 212's, and I think the 2019 is the same manual as some prior years. So...I search for "fogging" in the service manual, and nothing - zero hits - comes up. But I hear that "Yamaha recommends fogging their engines."
Any comments about why the service manual doesn't mention it, and from anyone who has fogged a TR-1, any comments about what exactly you did?
Thanks for any comments back.
I bought the service manual, and the one I was sent was for "2017-2018", so I'm left to believe the 2019 is the same as those years. There isn't anything in the service manual that uses the term "fogging", even though the owner's manual states on pg. 169 under Lubrication that "It is advisable to take the boat to a Yamaha Boat Dealer to have the engines fogged for long-term storage"
It's my wild guess that they don't want Joe Boater to do his own fogging due to some liability issue, hence the advice in the owner's manual, and that "fogging" the engines is the generic term used to cover the procedure
@4x15mph points to, because that's exactly what "fogging the engine" is, IMO.
Last weekend, I was pressed for time so I did what is laid out in section 3-20, which was to remove the air filter cover, and spray fogging oil into the big round opening - that's your air intake hose. The service manual states to do this for 3 seconds. You absolutely will NOT be able to spray fogging oil into the intake for 3 solid seconds, you'll have to do small bursts. I did the small bursts about 5 times, then sprayed until the engine died.
Since temps will be reasonable enough for me to work on the boat this weekend, I'll be doing the following for additional peace of mind, and NOT because it was listed anywhere - I will be pulling the spark plugs out, and spray fogging oil continuously for 4-5 seconds per cylinder. When done with that, prior to putting everything back as it was, put a rag over the open cylinders, pull the safety lanyard, and turn the key to distribute the fogging oil. Come spring, I'll run the boat to burn off the fogging oil prior to changing out the spark plugs with fresh ones. I'll also be running antifreeze through my engine. I've dealt with plumbing issues for the vacation place for the past 4 years, so for me, this really is for my peace of mind, and not because it's needed - enough folks who live in my state have NOT done this, and had no issues. I already ran antifreeze through the bilge pump and the scupper last weekend, and I hadn't gotten my pump/parts to run it through the engine, otherwise I'd have started earlier last weekend and got this all done in one shot.
