Inox or Lanox.
It's WD40 type sprays that affect insulations.
I like Lanox better as it's a bit thicker and stickier

Inox, Lanox are in no way similar in make-up to WD40 and the such.

I use Innox and at times Lanotech (same as Lanox etc) - Merc dealer that I trust says both are good. CRC, WD40 does wreck wiring. Mate had a 150 Black Max, religiously cleaned down and then CRCd at home after each trip - under cowl...after about 10 years the insulation fell away like goop.

Penetrol for the painted bits goes hard and dries clear, lasts years and years.
Armour all for the plastic bits and wiring, and silicone spray for the sliding shafts rods pins Etc.

I think WD 40 is not the same formula it once was, here is an excerpt from their website, I still don't use it on the boat motor but everywhere outside on the cars esp underbonnet.

What surfaces or materials are OK to use WD-40 on?

WD-40 can be used on just about everything. It is safe for metal, rubber, wood and plastic. WD-40 can be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40.

I use a lanolin spray on the outboard it is the bees knees that stuff.

Alan Downes told me last time to go very sparingly with the INOX. He said the insulation absorbs it and swells leading to failure eventually.
The last repairs on the trailer Brakes were also put down to hose damage due to Inox.
Dont get me wrong, I use and like the stuff, I just use a LOT less than I used to. It is still excellent for getting rubber marks of gel coat.

Just make sure that if you have any belts under the cowl you don't get any lubricant at all on them.

Some d%ckhead who said he knew engines told me to coat my V-Rod in Inox. I checked with a service agent first, and he said that would be a good way to blow it up, by causing slippage in the belts...

I have used Quicksilver Corrosion Guard for about 20 years. Outstanding product IMHO.

A noteable engine brand has brought out a "service advisory" to not recommend the use of inox (note: lanox is a diff product) on any marine engine as it is absorbed by the insulation and will turn the insulation hard.

Use a product called Tectyl 506.

It is a brown slippery rubbery spray and will last you out!

Only drawback is that it never fully dries and gets kind of messy to work around.

You may have to go to a bit of trouble finding it but some of the better hardware stores sell it or maybe Supa Cheap ......................?

Don't get the 121 version as this is only for new aluminium or parts.

LANox is fine.

From a Servicing/repair point of view 506 is just about the last thing I would want on an out board under the cowl! Cr@p will stick to it and good luck getting it off. Better off with a product that can be cleaned off and reapplied seasonally.

I was told by my dealer not to use inox as well under the cowl. They advised me to use "Mako Oil". Made up in MIssion Beach I think. I spray it on the motor and on the outside over the leg, smells a bit.
