Default Wd-40

Talked to a fellow boater this weekend. He told me that after every outing he sprays the entire motor with wd-40. Has anyone done this, and is there any danger in doing this? Sounds like a good idea to me. What do you think.

Won't hurt a thing but, in my opinion, utterly unnecessary.

Once every now and then, maybe. But after every outing?

We we purchased our boat (this is our third season with it) the engine had been "fogged" (an oil like substance sprayed onto the entire engine) but I have not sprayed it since. Into our third season with it now and there is no trace of rust anywhere on the engine.

fogging has nothing to do with the outside....fogging is where you spray a fine oil protectant into the carb while the engine is idling and then shutting it off as it stumbles ...the oil covers everything inside the engine ...protects against rust...

shouldn't be on the outside..

I spray all my moving parts, carb linkage, shift cable etc etc. I do this about every two weeks or so with WD-40.

If your in salt water I have heard that what your writing about is done every trip to keep the salt corrosion down. They spray the whole engine down.

I do this in the winter when the boat gets put away. Works for me.............

Was completely new to me SP. Was not until lafter we bought the boat that I came to understand what fogging meant.

From what I've read since then, the term fogging generally means as you said, but can also mean spraying down the exterior of the engine and electrical connections with the same fogging oil. From the Yamaha site: "Yamalube Stor-Rite Engine Fogging Oil is a general purpose lubricant that helps to protect metals against rust and corrosion. Conditions and protects neoprene, rubber, and other surfaces from environmental effects."

An oil soaked rag wiped over the engine will offer 1000x the protection against corrosion compared to WD40, i have read the list on its uses and use the stuff a lot, but its only real use is to displace water from and electrical circuit. if something needs lubricating use oil or grease

i did this to my jet ski motor. i rode about 95% in salt water. i also flushed the ski with salt away EVERY time I went out and sprayed it with a light mist of penetrating oil. Sometimes i used WD40 also. I used to go out once a week out of Long Beach. When i sold the ski you couldn't find a speck of rust on my jet ski anywhere. I am ready to start doing it to this boat. I just need to cover the drive belt when doing it
