I am new to boating and wanted to know what , if anything to spray on my outboard engine for corrosion protection. CRC, INOX, or just silicone spray?

Silicone spray, do not spray near the starter motor pinion gear. Do not use CRC

Any negatives (apart from cost) with using Lanocote or Lanox? As of late Ive been using Lanocote.

lanocote dries tacky. i find it great on the trailer as it forms a water repellent barrier that stays on even after dunking the trailer. but i wouldn't want it on my outboard, would be messy and a damn nuisance to get off.
 
i have a few cans of silicone in the garage, will try those. are they good at rust prevention?

I've been using CRC without realising it was no good - will it have done harm?

I was told you flush the engine, then spary silicone done the hose and flush it again.

I use Prolan - Its a N.Z. company and its base is made from a natural product (wool grease)Emoticons

CRC tends to swell spark plug leads and other electrical plugs/connectors, long term you will need to replace items to fix the damage.

Thanks for that; nothing worse than thinking you're doing the right thing and finding out down the track that it wasn't just a waste of time but you've also mucked something else up...

I use Inox and Lanox on virtually everything fishing related (engines, trailers, fishing rods, reels etc), so far no issues after several years, but I am not a chemist.

Silicone spray is a house wifes myth, its good for nothing I tell ya nothing at all.
I have seen switches and electronic components destroyed by silicone, upholstery, paint and all sorts of stuff that has been killed by silicone.
If even a micro spot gets on any surface that has a current running through it, it will form into a carbide (a very hard substance that is not very good at conducting.and eventually in sensitive electronics this will mean dead to thems..... 
Painters hate it also , plague of the modern world
 
CRC is not going to protect anything its the same as washing it in solvent
( itll be bone dry in about a day)
 
Lannox and Inox are mildly better at lubing and protecting, being based on lanolin they arent going to cause the problems solvent based lubes will.
 
But my advice on an engine is dont use anything on it, the factory coating will be fine IF and its a big IF
 
If you keep it clean , warm soapy water and a rag is the answer.
 (car wash detergent is best as it is a mild detergent not a strong harsh one)
Keep every nook and cranny clean and dry all the time , like you would/should  your cars paint.
If you do this religiously and thoroughly you will have no problems.
First big clean can be a mission but if done right its a simple easy task to keep it clean and corrosion free....
Clean is mean anything else is a compromise....................
 
Once its all clean and hunky dory
use canuba wax on it (car polish type product) this will eventually soak into its pores and keep it easy to clean and good to look at.

Nope again to wd40.
 
There is an aerospace-style protectant that forms a aliens-style skin over everything, if you start from new this stuff will prevent any corrosion or damage purely because nothing can get to it...
 
But, most of the time the inside of the engine where the saltwater runs is where the damage is occuring...

I've used silicone spray for 10 years with never a issue, rubbers all good and pliable still, metal well protected, water beads off surfaces, I even coat electrical connections and have never had a problem - it definatley keeps moisture ingress and surface rust away if used regularly, salt has trouble sticking to it.  I have never experienced any of The Dogs issues though, but agree if you ever need to paint anything it's bad news, but can't see why you would under an engine cowling anyway.
