Would you spray your outboard with WD40

[nickjaxe]

Hi all for many years after I have used my boat I give it all a good hose down, flush the engine YAM 55 outboard and give the powerhead a spray with WD40 to try and keep corrosion at bay, I must say the engine still looks like new and it is some years old, anyway a few people just lately have said that spraying the engine with WD is a bad thing, can rot rubber ect and said I would be better using waxoil, I was thinking this would be a bit messy, what do you guys think.

Nick.

I know the Yam 55 unit very well, WD40 is fine, Your mates talk bullshit. Carry on as you are and keep flushing after every use, then spray with WD40, or at least an equivalent.

Nice to see an owner that cares!

Contrary to popular belief, WD40 although an excellent product, and a legend in it's own lunchtime!............... is corrosive.
The product was designed years ago purely as a releasing agent for easy removal of rusted components nuts and bolts and other type of fixings, to which end it works marvellous!!.
However, the process by which it performs this wonderful task is due to the way the product attacks the metal/rust bond, basically it eats away at it causing the two parts to shrink away from each other hence easy removal, brilliant!
Part of WD40's formula which is top secret btw, also includes a water repelling agent,so everyone sprays it all over their car/boat ignition system, and Bingo!! engine fires on a cold damp winters morn.
But users of the product soon found out that thier H.T. leads were not living very long after prolonged treatment.
So spraying your powerhead or any other part of your engine, with WD40 is not such a good idea IMHO, especially for winter layups or other long periods out of the water.
Waxoyl would be a messy going on as an alternative means of protection, and certainly a devil of a job to clean off.
What does Yamaha recommend as a 'fogging oil' for your needs?

hi
I've gotta agree with DaveS, nothing wrong with WD 40 main ingredient is Fish Oil,
can't see how that is corrosive!!!

I would go for it with the WD-40 because you cannot lose.

The WD-40 Company specifically recommend WD-40 for spraying outboard motors on boats (among many other engines). So, if your outboard rots as some are claiming, I guess the WD-40 Company will be happy to buy you a new one. If it does not rot your motor, then you are doing both of the right thing and setting an excellent example.

It was never originally designed as a release agent. It was designed as a water displacing anti corrosion agent for the aerospace industry, and one of it's first uses was in protecting the outer skin of the Atlas missile from corrosion.

WD40's own website states it is perfectly safe for use on rubber, plastics and painted surfaces. Given the litigational nature of the US, highly unlikely they'd make such a claim is untrue. It's a hydrocarbon oil, difficult to see how it could be corrosive

Unless we are talking about different things I think you will find that the "Atlas Missile" is actually the "Atlas Rocket" Subtle difference you see/forums/images/icons/cool.gif

A former poster on here, Tomo, used to be a WD40 dealer and he said this idea that it was corrosive to rubber was totally incorrect. I've used it for years and so far no rotting rubber pipes!

predated Atlas rocket by quite some years. As far as I know, they never used WD40 on outer skin of Atlas rockets, but please feel free to correct me if I'm wrong /forums/images/icons/laugh.gif

You and Moose are probably both confused by Charles Atlas's use of WD-40 on his outer skin.

Just to be pedantic, and before the product police knock on your door, it is WD-40, not WD40, so there /forums/images/icons/smile.gif.

Well I wouldn't use wd40, but only 'cos in my exp. it tends to dry to a sticky goo that attracts dust rather too soon, compared to say GT85 or others & thus need cleaning off more often.



re "The product was designed years ago purely as a releasing agent for easy removal of rusted components nuts and bolts and other type of fixings, to which end it works marvellous!!. " I've always found it very poor compared to plus-gas, but better than nothing of course.

It is good for easing home banks of 4 carbs on bikes where the airbox rubbers have got a bit hard or access is awkward, then the fact that it dries & sticks after a while is a positive benefit. & no, it doesn't attack rubber in my exp. Well, rubber maybe, but not most soft plastics used on bikes/outboards/cars.

Don't use waxoyl.

I have so far having sprayed about 20 litres of WD40 around our boat, although not all at once. No damage yet!
