Re: SPORT 120 MERC BRRRRR!
same as any other outboard. clean it well and spray a preservative like fluid film on it, treat the fuel with a stabilizer and run it long enough to insure its gets the treated fuel to the carb. DO NOT run that sport jet on the consumer flusher, MUST use the dealer flush fitting that requires removal of the seawater intake line from the power head adapter plate.other than that its a mater of protecting all shiney surfaces with fogging oils,proper greasing and changing the drive and stator housing oils. use only merc HP gearlube.
