Engine paint prep

[PabloPicasso]

Have a little marine engine with some rust, dirt, oil on it. Any advice on what to use to remove oily residue to get ready for painting?

I have some fertan to treat the rusty bits once the worst has been wire brushed off. I can wipe the worst of the detritus and oil off with clean rags, but I've not painted an engine before.

I used Gunk to degrease mine before painting.

Agree will previous poster, spray with gunk, use an old paint brush to work it into all the crevices, hose off with fresh water using a pump-up garden sprayer which helps to direct the water to only where you want it, then gunk again, hose with water and allow to dry. Paint with hammerite no.1 rust beater primer then 2 coats of hammerite smooth paint. I did this 16 years ago on my engine and it is still looking good.

Edit: correction to the above, just checked my notes, I painted the engine 20 years ago! How time flies.....

Paint it in Volvo Penta Green. You'll find that all the spare parts magically become much more expensive?

No, you want Yanmar grey for that

Which colour ?
As an alternative to Hammerite , there are sources for engine enamel on the internet. Volvo Green and Perkins Blue(couple of types).
Pretty certain there is also a Dark Blue for Yanma.
Around £15.00 for 1 litre.
Avoid those teeny weeny aerosols at a ridiculous price.

I did my Bukh with red Hammerite smooth many years ago. At the time I reckoned that it was probably what Bukh themselves had used, colour was identical.

Much more recently I have been painting disc brake calipers, also red. The guy in the shop could have sold me expensive paint specifically targeted at brakes but he advised that he used Hammerite, which took the temperature perfectly well.

I found when repainting my BUKH engine after a major overhaul that smooth Hammerite was more durable and less prone to chipping if applied direct to the steel, ie without an undercoat or primer.
