Location: Madtown, WI | I just performed my first 4stroke winterization on a mercury 90HP, just as described by VMS (although I didn't turn engine by hand). Really is very little to be afraid of, if you can unscrew a bolt and pour a fluid you will get through it without issue. The bottom spark plug is a big tricky though, I more or less had to assume I was spraying into the cylinder but got it back in without too much trouble.
Also, I just start stabilizing my fuel in November jic it ends up being my last trip. |
