i would agree with cookee nowadays , though 20 years ago i wouldent have dreamed about doing it ,with the old points /condenser /flywheel mag ect keeping things dry was crucial from saltwater corrosion and having things short out ,but with modern cd/ ignition units ect ,things are more solid state and waterproof , and lets face it its suprizing where salt water can get to, little tiny nooks of the engine that may go unoticed for years ,until something decides to drop off or snap off, if its wet with saltwater im pretty sure a fresh water rinse a few times of the year wont harm it and a good liberal spraying of wd40 or something .

really,dont worry about it, this weekend after the fantastic Jolly to the folly, was very rough on the return,, some near vertical jumps buried the engine on the rear.. when i got home and lifted the cover off, white salt water and residue all over the engine, out with the kettle and doused the engine. electrics, in fact everything with warm to hot water, then blow it all down with a compressor< lucky to have the luxury of a big enough garage where i leave the hood off to ultimately dry till i need it the next time.

if you give everything including all the electrics a good 3 or 4 coats of quicksilver corrosion Guard, it will do the job,also put in vaseline in every electrical connector and block connector you can find.

there is no way i would coat the engine in WD40 , I also look after a very large collection of vintage and veteran cars and i would not use WD for coating any of those either!!

Because of the electrics?
The corrosion guard seems to be the best stuff but the RNLI have us spray them with WD after rinsing off for some reason?

hi chewy,

I have found that WD40 attacks rubber, sure this has been discussed before, anyway, few years ago i was restoring lagonda self jack system on the vehicle, i had lubed the rubber seals with WD, following day, literally jammed, rubber bung as it was, gone like a silicon donut!! Yum Yum,

also attacks window rubbers and carb diaphrams quite badly as well, i thinks it really depends on what your putting it on but i would never risk it on my prized lump!!

suppose it depends if you are using it on something on which the rubber products are on their way out anyhow due to age ,i bought 2 brand new yamaha out boards in 1976 and all i used was wd40 on them after usage right up until i sold them a couple of years back all the rubber and plastic components were fine couple of the fuel pipes had started to craze a bit but they were 30 years old .,,,with regards to your lagonda the original factorywas about 2 miles from where i live now in its very early days ,,apparently they tested out some of the cars on the only staight road in the area ,early on sunday mornings so the local plods couldent catch them ,,,anyhow the plods dident have any cars fast enough in those days ,

Cheers guys! I must admit that after 7 years of RIB ownership I have never cleaned an engine once with the hose. To be fair though, the boats I've owned have only had light use, but in some respects I supose it is more crittical to wash everything off if it isn't used as much.

It's only because I noticed that the bottom two spark plugs were getting a bit rusty that I even though of an application of the spray.

I like the Idea of the Kettle, because my outboard is stored outside it'll take alot of time to dry out before I can use the spray. Hot water should help this drying process.

So thanks again!

think best way after you have cleaned it is to run it up on the hose or tub for a while and get it warm and drive out any moisture ,lower plugs always seem to corrode a bit ,think they can get spray kicking up on some engines or they run cooler and that may have something to do with it ,

Well I went and did it yesterday. 5 kettle fills later I ran up the outboard for half an hour just to get some heat into the block. I've left it over night and finished drying this morning with the aid of a hot air gun. I've just given a squirt of the Quicksilver stuff in every nook and cranny that I bought off Ebay and am now washing the Cover in the Bath tub.
