fogging oil

[gary Surak]

How do I treat the cylinders after using my ski in the sea water? I learned about fogging oill and where do I spray it in? What is the purpose of that and what kind of oil can I use. I read about WD-40 and will NOT use it. Do I need to remove the plugs and spray it in? If I do not have the spray can I just pour oil in the cylinders? I will use my ski in the area where those sprays are NOT available and I have to use basic means to maintain and keep the ski from corrosion.

Re: fogging oil

Fogging oil comes in an aresol can and is usually sprayed into a Sea Doo through the holes provided in the air box ( under the removable rubber plugs) or through the air box inlets, while the motor is running at a fast idle. It dispels any water from the metal parts and puts a protective coating on all of the bearings and the clyinder walls.
You are susposed to do it each time you finish riding the ski for the weekend. Rust can form in 24 hours or less if water is present in the motor..

Re: fogging oil

I did purchase my SD 720 from a friend who put only 30 hrs on it and the engine seized d/t sea water not being flushed out. He told me that I just attach the garden hose to the back of the ski (by the pump there is a 3/4" attachment) start the engine and run water a few minutes, shut the water, rev a few times and turn off the ignition. I want to make sure I am doing everything possible to keep this engine since I hand carried it from SBT to overseas on the plane. I am afraid that by replacing the engine I have not removed the cause of the engine seizure: the ski stopped in Ft.Myers, towed to the dock, transported to the dealer where it was left untouched for 3 weeks what killed the engine. I did install new SBT motor but what else do I need to do to make sure this does not happen again? Also I will replace the exhaust pipe.

Re: fogging oil

Makes sure you clean the fuel system. Selector valve, external ( under the front cover) and internal fuel filters ( those are the ones inside of the carbs).

Makes sure the oil pump is bled and pumping oil up through the two small oil lines into the intake cover. Check the alignment of the oil pump lever, adjust the cable as necessary to align it.

Re: fogging oil

Bill,

I have switched to premix. The regular maintenance in the sea water is what concerns me. The engine has not yet been started and needs to be broken in ( I will do that in the river). There were some hoses that lead to the muffler that were clogged but I would need a check list of what to do before I start the engine and what after I finish. Is there any article on that and where? I looked but couldn't find on this site.

Re: fogging oil

Gary here is a good post regarding flushing posted by another member just today in reply to someone else asking about it. Not sure if this is what you are completely asking about but it does seem to answer some of your questions. To whoever posted this sorry not to use your name but I forgot in the time I copied it and pasted it due to dealing with the litle ones.

#1) Connect the flush kit and water supply to the ski.
#2) Start the engine.
#3) Turn on the water.
#4) Let the water run until it is clear, usually a minute or two.
#5) Turn the water off.
#6) Spray fogging oil into the carb.
#7) Turn the engine off if it has not died from the fogging oil.
#8) Disconnect the flush kit and water supply.

That is pretty much the procedure for a fresh water ridden ski. If you ride in salt water you will probably want to use a salt inhibitor when flushing and also rinse the entire ski (in & out) and spray the engine down with fogging oil. Also rinse the trailer well.
To make it easier to turn the water on and off get one of those ball valve adapters that goes on a garden hose. That way, when you forget to turn the water off before turning off the motor - which is what I usually do - you can get the water off without having to run to the spiggot.
A couple other things, First don't run the ski for more than 20 - 30 secs w/o water connected. Don't run the ski for more than 3-4 minutes with water connected. Don't rev the ski real high when it's out of the water. And finally, be sure you know the correct way to upright your ski after capsizing. Most skis have a lable on the back showing the correct direction to turn the ski. If yours does not then, usually, you want to turn it so that the exhaust is at the lowest point when turning it back upright.
Hope this helps and good luck with the new motor.

Re: fogging oil

Other than normal maintence, I spray the whole engine down with WD 40 before I launch in salt water, then when finished riding it for the day, I spray the ski and the motor off with soapy water ( keeping it out of the air filter ). I then start the motor, turn on the flush hose, rev it a couple of times shut off the flush hose, fog the motor. Grease all zerk fittings on the pto and the trailer bearings.

For break-in, I ride it like normal.
