Mid Summer Maintenence ?

[Geiger41]

So I have about 55 hours on my 212X, 50 of them were last season. For last winters winterization I changed the oil, fogged, CRC'd the entire engine compartment. No flushing the engine with anti-freeze, I simply blew all the water out. After one of the coldest winters in history here in NJ Im convinced anti-freeze in the engine is not needed if you flush the engine out real good. I also did a few other things

My question is should I do a fogging during the summer once just to help lubricate the inside a little during the season ? Also I have'nt changed the spark plugs yet, was going to do that after the season. Should I remove them and spray some anti-corrosion in the plug chambers ?

I wouldn't. Just run it. Change the plugs now if you notice the engine running "off". Otherwise, I'd change them next spring. Reason: I wouldn't want to put brand new plugs in at the end of the season and then immediately fog the engine. The plug chambers shouldn't need any anti-corrosion sprayed in there if you're running it.

If you are boating in salt water @geiger41 , absolutely do several in season fogs. Yamaha has a special tech bulletin out that recommends this as routine, not just annual. If done like they recommend, it won't foul plugs. I would also absolutely run Yamaha Ring Free in every tank if I was in a salt environment. I do both of these things even in fresh water only. If you want the tech report and info, let me know, I have posted it so many times I hate to do it again unless it is needed.

 

[Geiger41]

Good info, I have some Ring Free in the garage, Ill pour it in next time I take the boat out. Ill do a fog also when the cover comes off. As far as the tech sheet, Ive never seen it. Ill do a search now and see if I can find it, if not maybe send me the link.THANKS

@txav8r thanks for the info and article. I'm curios though, does this happen? "Especially after each operation in rough conditions where saltwater spray may have been ingested into the engine"

Our boats engine compartment are basically water proof. When I ride no water ever gets in there so im not sure how this could happen....

This info is great, Ill use it for my 212x and fzr

 

[txav8r]

I don't think it is spray ingestion directly, but the salt air that is continuously ingested that will cause the rusting. However it happens, Yamaha seems to think that the fogging and Yamaha Ring Free will prevent it. I think if I were in the salt environs, I would use it no matter what craft I owned.

 

[Geiger41]

I think I'm gonna pull the boat and do some stuff to it. Fog the engines, wax/clean check oil levels up and a few other things. Its hard to do some of these things when the boat is on my lift. Figure once in mid summer is a good idea. Then after the season I can re check everything

@geiger41, @txav8r is correct with regard to the salt in the air being the culprit as I boat exclusively in the salt and never get salt spray in the engine compartment regardless of the wave/chop. I have adopted the frequent fogging routine per the Yamaha bulletin.

On another note...Last season I experimented with leaving the plugs in for a 2nd season. I just changed them this spring and looked them over very close for signs of carbon and rust. They looked just as if they only had 1 season on them. Now, I did coat them liberally with anti seize before installing them 2 seasons ago and I only put 25-30 hours on per season but I'll continue with every other season with the standard plugs.

 

[Geiger41]

So I pulled the boat out of the water to do some stuff. I will send pictures of what I see underneath the boat along with any other issues or questions I have besides this one.

My dealer told me to do the antifreeze not as an anti freezing agent, but more of a lubricant.

 

[Noko]

I didn't do the antifreeze or blowout my engine exhaust and I had no issues. My boat sat in minus 20F this winter and no issues when I started it up.

 

[txav8r]

Noko, your a lucky man. ALWAYS blow out your engines.

Also, dealers don't deliberately mislead you, but when I hear the words, "my dealer told me", I cringe. Because they may not even be boat owners and operators. The members of this forum ARE FULLY INVESTED AS OWNERS AND PROVIDE REAL WORLD EXPERIENCE AND KNOWLEDGE. I have recently acquired a motorhome, and I have already been mislead by the dealer three times in 3 months.

Lubricant for what, your exhaust? The only moving part in the cooling system I can think of is the thermostat. Sounds like this dealer was an IO guy used to water pumps.

 

[billyb]

So you are not supposed to run antifreesze through as a winterization procedure?

 

[GiddYupJoe]

@billyb I believe you are the winner for the first member to say the word WINTERIZATION this boating season!!!

Funny thing is that it was my dealer who told me to always blow out my engines, every time. Also the one who told me to pull the plugs every time so they don't get locked. Guess I am lucky.

Sounds like you may have a dealer that is also an owner. OR at the very least he wants to be knowledgeable about what he sells. Good find. Cherish it.

Ok...is there anybody else that finds this tech bulletin strange. Man, if your operating your boat in conditions which resulted in your engines ingesting salt spray, you're going to need more than a can of fogging oil to fix that problem. Looks like the poor SOB's that have supercharged engines need a complete engine tear down after each use! Spark plugs are pretty fragile...I don't know how many times I want to loosen and tighten them. If fogging is that necessary, why not include a port to spray the oil in, rather than have to disassemble the air filter each time. They don't recommend this on their outboards, why on their purpose built marine engine?

 

[txav8r]

These engines ARE purpose built marine engines.
