Spraying Down the Engine
Please share some thoughts about periodically spraying the inboard diesel engine with a product such as WD40 or T9.
Does it help prolong the paint and stop rust? What about odor or fumes when the engine is running and hot?

Re: Spraying Down the Engine
Can't hurt. The 'WD' in WD40 supposedly stands for 'water displacing' and does seem to keep the rustermites away on my tools if I remember to spray them down with it. Boeshield, etc have a wax additive that remains on the steel further protecting the surface. Might cause a buildup of crud if/when it gets mixed with dust. Still, only a cosmetic problem that may require occasional washdowns with a grease cutting solution and recoating.

Re: Spraying Down the Engine
We make our own, diesel and outboard oil 80/20 respectively. Works a treat. Outboard oil TCW3 has good adhesive properties.
Will keep things shiny for a long time and prevent corrosion. The solvents in some products, and the propellents play havoc with hoses and some seals.

Re: Spraying Down the Engine
I do that when I winterize, it does smoke a little in spring start up. I don't routinely do it during the year.

Re: Spraying Down the Engine
I have used mineral spirits to periodically clean the engine.

Re: Spraying Down the Engine
I liked the Quicksilver (Mercury) Corrosion Guard stuff in a can. Sprayed on like WD40 but dries to a wax finish to protect. Since I don't use much I don't mind paying the price for a can if we can't get any at work.

Re: Spraying Down the Engine
I prefer fluid film. It is a lanolin based product.

Re: Spraying Down the Engine
Cleaning, de-greaseing, and washing the engine and engine room is a job I do every time I make a ancorage for a day or two! That of course depends on the running time on the engine on the trip we just finished. If it was only an hour or two I wont clean it this time !Its just one of the things Ive always done at anchor, some say its a bad habit but it works for me !! and keeps me busy LOL

Re: Spraying Down the Engine
Lanolin spray might be good too.

Re: Spraying Down the Engine
WD 40 is not recommended for this purpose, it will degrade rubber and plastic products. Silicone spray will protect better and cause less damage.
