Location: Kodiak, AK | Nope. Stabil does nothing to prevent a slug of water or entrained water from being sucked into the motor and destroying a piston, nor does it filter out particulate contaminants from clogging injectors. I know alot of guys run boats and motors without them, and have for years with no problems. But for the $50 it costs to buy and install one, and the $15 every few months (or yearly, depending on use) for new filters, it's just cheap insurance and should be standard equipment IMO. |
