De-grease before applying corrosion spray

Hi, I have a question about using corrosion guard or other sprays after using my outboard.

Quicksilver Corrosion Guard says that you should de-grease the engine before applying. I want something to spray on my engine both outside and under the hood after every use to keep it in good condition. I've heard that you should douse the engine in hot water to remove salt deposits and then spray with a corrosion guard, but I don't want to have to de-grease my engine everytime I do this. Would it be better to use something like GT85 spray? Can these products be used on the rubber components safely?

I sprayed my engines with BRP corroguard when they were new 5 years ago. I've not re-done them since & they are like new. I rinse the powerheads off with the hose pipe after every outing. I didn't degrease or do any special prep before I sprayed them.

You'd know if it had been-or been oiled up in any way as it's quite visible.

I gave mine a warm water spray then let it dry and degreased it with Halfords brake cleaner.The brake cleaner will emulsify with any odd bits of water you miss water and dry it quite quickly too, so no need to leave it out for hours to dry, just don't spray it on while it's soaking.
Wear goggles and watch the paint! It does give you a lovely clean surface to apply to though.

Wasn't there some stories going around about the BRP stuff attacking rubber fuel lines etc.? I'm sure a dealer told me they stopped using it for that reason

Be aware that factory delivered greased parts and assemblies could be washed off if these kind of prducts are directly sprayed to them...

Happy Boating
