Anti-corrosion sprays

The other day I removed the hood and had a peek underneath. Everything was fine except some corrosion around the lower spark plugs. There were also some small drops of water in area's I just couldn't reach.

I must admit to never using an anti-corrosion spray under the hood to disperse water and protect the block and electrics etc, so am seeking some advice.

I guess you just spray this stuff everywhere. So my question is: Dosen't the wax, oil or whatever just attract dirt after a period of time and if applied yearly will it just build up and make the engine dirty (like the electrics on a car if sprayed with WD40)?

I would be interested in hearing from people that have used such products over several years and what products they recommend.

Completely de grease the engine/electrics and dry with compressor ...then 3-4 light coats of Quicksilver corrosion Guard, every so often after the engine has had a spray of seawater on it i pour hot water all over it to disperse the salt marks.


also before all the above...all of the electrical connections are pulled apart and bullet connectors and every terminal are filled with vaseline!!

all the electrics in the consol and under the outboard saddle get this abuse of me!!

forgot to mention, dont breath it in, its not good!!

After every exercise we rinse the engines off with fresh water, run them till the thermostat opens then spray with WD40.

I'd be carefull with WD40 I've been told it starts to eat electrics after a while!! I prefer the quicksilver stuff mentioned earlier.

Don't think it does the HT leads much good but it seems fine on everything else.

I've ordered the Quicksilver Corrosion Guard, thanks for the heads up Matt.

I am however a little worried about the pouring of water over the engine to remove Salt etc before I start to coat the engine. There a hundreds of electrical connectors, sensors and all sorts of things that don't react nicely to water. Throw into the mix inaccessable area's of the engine and it seems like an impossible task.

Does anyone know if there any cleaning sprays that I can use that wash the dirt off the surfaces of the block etc and then flash off to leave a residue free surface in which to use the Corrosion Guard?

Couldn't disagree with you more!

Just think of all the spray that gets dragged in with the intake air to all those nooks and crannies - which would you prefer - highly concentrated damp sea salt rotting everything away being heated up and cooled down or all of the above flushed out with fresh water?

Don't forget you are washing down a boat engine!

Our race motors get hosed down, sprayed with Worth water repellent spray Ultra 2040 and it even keeps the head bolts looking like new - and they aren't even painted!

I'm very surprised you can douse all the engine in water spray.

So just to claify, you're saying is it's OK to spray water all over the ECU and associated components then?

So long as they aren't hot - warm is ok though - it will help remove the salt deposits from the motor, and together with the spray will help prevent the corrosion that the salt will promote.
