Noticed a few light rust marks starting to form on the engine the other day.. Was thinking a light coat of something like WD40 would be a good idea but then thought to ask the question rather because I am sure there is probably something recommended by all on here as the best way to stop corrosion on the engine..

So how do you stop corrosion on your engine?
 
My engine sprays oil all over itself to prevent corrosion.

However, a basic aerosol lacquer will do the job better than WD40 which lasts about ten minutes!
 
ACF 50 available via amazon, nippy normans.
once you have used it for most boat items you wont want anything eise

+1 for ACF50. Not needed to use it on my new Beta but it s doing a brilliant job on my anchor windlass.
( and my GSA. Buy it from Nippy Norman, he's a good bloke. Amazon sux.)
 
I wrap mine up in a blanket. This stops condensation and thus rust both outside and inside the engine. This works for outboard motors stored in the garage, too. A polyester blanket is best.

I use Waxoyl quite a lot. Sprays on but dries to greasy substance. Too crude for engine paintwork, except possibly for places you cannot get in to paint. Tried ACF50, but was unconvinced about its durability.
 
No Damp in my engine room but I feel sorry for the engine in there all alone on a cold winter night so an electric blanket a nice snooky polar quilt and comfy pillow. Joking aside I have never heard of ACF50 but will have a look we use an excellent product called Corrosion X, they make a oil spray and a grease spray and trust me once you have applied it it STAYS put. I have seen a chap at a trade show spray a 240v drill and then put in his hand underwater and use the drill.
 
I've never had rust on my engine, I always leave the engine bay covers off and make sure the engine bilge is dry when I leave, if it's not damp it wont rust.
 
I think it always a good idea to wash the engine in the winter with 'Gunk' or similar engine cleaner. This washes all the salt from the surface which is the prime cause of the corrosion.

Salt is hygroscopic, it attract moisture. The combination of moisture and salt is a killer combination.

Reduce the incidence of this by a good wash. When it is dry get the flaky paint off, and clean again and let it dry.

Then spray paint prime it and get the right colour preferably from manufacturer and spray paint it a couple of times.

Metallic paint seems to last longer and it bakes on when the engine is hot.

In my opinion there is no substitute for this treatment. Corrosion sprays are a cop out, they may work temporarily but the salt is still there when this dries out.

This treatment has always worked for me, takes longer but it is well rewarded by a nice clean bright sparkling engine.

I been using plain old vaseline for years now.
creates a good air & moisture barrier, stays put and won't dry out.
does for electrics too.
straight from the medical cabinet.
theres a rust spot on the van getting some of it tomorrow.
