Protecting/cleaning your outboard engine

[Rum_Pirate]

When we return I normally take off the engine cowl and give the engine a liberal spraying with CRC Formula 6-56

as a 'guard against corrosion'.

Which reminds me I need to do it this week (first spray for the year).

I use the CRC because somebody said that WD40 tends to breakdown the insulation on wiring and runner type parts faster than the CRC.

Judging by the photo's you've recently posted you don't need an outboard engine - chuck it in the drink and let the world go by...... slowly!

WD40 does not break down the insulation, it corrodes copper over a short period of time, this means the conductor in cables and contacts in various connector plugs if they are copper or zinc plated copper.

I never knew that.
