Is it important to spray the engine,motor head,relays,throttle cable,rubber hoses and everything else I can find to spray with WD-40 on my 2 stroke 90?

I would be a little cautious about spraying any kind of oil on rubber hoses or other rubber parts. Unless the rubber is made of an "oil-proof" compound, you will cause the hoses to rapidly deteriorate. I imagine that a silicon spray would be better for the rubber parts.

WhalerRon is probably right about oil on the rubber, BUT, ever since I got my first Whaler, I have been spraying the entire inside of the engines with WD-40. I do this everytime we come back in. I buy it in the gallon cans and use the hand sprayer. I give everything a LIBERAL (even though I am a Conservative) dose of WD-40 -- motor, relays, connections, anything that does anything. I would rather have the oil there than the salt spray.

Just MHO.

There are, supposedly, better products to use than WD-40, which is actually a petroleum based solvent, and removes grease, lubrication and oil (which you don't always want to do!). This I am told by my Mercury mechanics in FL, who DO spray the complete powerheads on my engines with some product.
But I don't know what it is! But it does leave a film on the engine. Check with your engine delaer for the right product to buy.

Funny, I live in the saltwater capitol (South Florida), and I only spray WD-40 under my engine cowling about once a year to keep everything looking pretty. However, I make rinsing the boat and engine an after every use habit.

CORROSION X is the name of the product i use. i take the cover off and spray down the inside of the powerhead (avoiding under the flywheel) with fresh water using a garden hose nozzle. i immediately start the engine and let it dry completely. then i spray the whole thing with corrosion x . it seals the entire powerhead, does not checmically affect rubber or electrical (except in a good way), and does not disappear in a fortnight like wd 40. it puts a skin on your engine. do this once a year and you wont have any surface corrosion. not good for the outside, though. better off to use grease in those situations if you can. about $8.99 for a big arousal can. steve out ps you might have to use paint thinner and a parts brush to remove old oil and corrosion if its an old or dirty motor, especially for the pan. be tidy and put down a cathching pan or dropcloth when you do this.

Ditto Steve- it's Corrosion X. Fine stuff.

I've had a 1975 40hp merc on my 1970 13' sport. The last time I used it was in 1982! The only thing I've done to it was during winter storage. I would remove both spark plugs and pour a can of Mystery oil in each cylinder. After 20 years of non use, I hooked up the battery and in a cloud of blue smoke she started right up! By the way, salt water use!

I was told that WD 40 actually causes corrision and not to use it. Initially it works but then causes corrision.

Silicon Spray is the product to use! The Yamaha, Nissan dealer near me sprays the entire engine with silicon spray. This should be done every six months to a year. This will not eat rubber and does not dissolve grease on the linkages etc.

Incidentally a buddy of mine sprayed the heck out of his prop nut, prop and shaft with WD40. A couple of months later he spun his prop out of the rubber bushing. He believes it may have been due to the liberal dose of WD40 that he gave it.

JayA, i believe we were talking about people who use they`re motors in a corrosive environment continuously. I don`t think it is such a concern if the motors are used only every 20 years or so. although crank end seals tend to dry out and become more brittle if not juiced every now and again, steve out.

Eddies, that Yamaha stuff is good! the only setback is the price. Don`t they want about $18.00 a can for it? steve out.
