Jet washing an outboard?

Hi guys,

Do anyone jet was the outboard to remove the salt and dirt?

I have read in this forum about kettle washing, once all the bullet connectors are properly filled with Vaseline, but what about a jet wash. Any counter-indications?

Say, if I jet wash it with foam, then rinse it, then let it dry about 1 week before next use, will it be ok?

Cheers

I wash the outside of the engine, indeed the whole boat & trailer with a hot washer. I set the temp to around 70deg and CAREFULLY wash off the whole outfit. I keep a good distance away & use a fan nozzle. This gets all the salt out of the nooks & crannies. I then remove the engine cowl & rinse off the powerhead using the fine watering rose on the hose pipe. Let it dry (flush the engine first so it's warm, helps it dry quicker) I then use the blow gun on the compressor to blow any remaining water away. Finally a spray over the block with silicone spray. Job done👍

Good, mate!

But what about jet washing the INSIDE of the outboard, under the cowl?

Btw I was using the silicone spray as well, but red about the Quicksilver Corrosion Guard, gave it a try this week end, seems very good stuff

I have had good service from corrosion X HD spray, perhaps similar to the quicksilver stuff?

Braver man than me to be pressure washing inside an Engine! I assume being very careful is mandatory.

If you want to clean the engine under the hood get some bargain WD40 type spray (not an engine cleaner spray!) and spray all over using a small paintbrush to agitate off any stubbon dirt. The spray off again using the spray's pressure to "wash down" the dirt.

Dry excess off with a rag.

Trust me as someone who ran his own motor engineers business I know jet washing an engine under the hood can mean instant death to electrics/connections and a slow seizing of pivots etc.

I certainly wouldn't jet wash under the hood. I've used the waxy corroguard type sprays in the past & they are good, the problem is they make the engine horrible to work on afterwards, it's a sticky messy gunk especially when warm & makes the engine look old, good stuff though. Silicone is cleaner & looks better IMHO. Personally I wouldn't use WD40 as it can soften rubber hoses. As for removing salt, salt isn't soluble in WD40, the best stuff to get rid of salt (IMHO) is warm water.

Yep as Jeff says WD40 not a problem for rubber if just sprayed on as a mist and wiped off. Some rubber hoses react to being immersed in WD40 long term.

Agree re heavy salt buildup... rather than jetwash a warm jug of water gently poured over is OK... and then when dry WD40.

dont forget hoses are fuel grade and heat resistant WD40 is going to do far less damage than salt water and once the water has been dispelled a clean rag will do the rest but for me no water should be put or enter under the hood.
as an alternative
