Does anybody spray their motor down with WD-40 before putting away for storage if the boat will not be in temperature controlled environment? What are your thoughts...good or a pain to clean up in spring? Thanks!

I did it on my 502 Mags and do it on my neighbors 5.7 every year. Fire it up and go in spring.

Nothing to clean up? Does it make a mess or burn off and cleans everything that gets wiped? Spray everything down? Anything to worry about with the wires/electronics? Thanks

wd40 is 80 percent solvent,i recommend useing marvel mystery oil as it is much better at inhibiting rust.

All you have to have is an oil leak (Like I did this year) where the pan/block/timing cover meet and the harmonic balancer will distribute1 a nice thin, oily film, coating everything in your engine compartment. Built in protection system.

I covered everything thoroughly. It's about gone by spring. Fire up and go. I don't know about Marvel.
I wouldn't do it to my 575's though.

Used WD-40 for years on my snowmobiles and it works great. The new "big blast" can is awesome for big areas.

S100 makes a corrosion inhibitor that works well on engines
if you have headers i would wipe off in spring
When I lived in florida I used pledge on the harley engines to stop the rust and corrosion worked well and lemon scented

Factory option?? Because mine has that feature also

do mine every year .when i worked at the marina every boat got it and we winterized about 400 boats every season .spray it on in the fall and it will be gone in the spring
