new to me, 94 Merc 90hp
 

Just bought a boat with a 94 Merc 90hp. I plan on trying to go through everything in the motor that i can. the motor hasn't been run in a year or so. Can you experienced guys give me a list of things to check and/or change.

I would change the water pump,fuel filter,spark plugs,ect. Be ready to clean the carbs if it sat up for a year. You might get lucky,but with todays gas it does not take long.

u can also spray a can of sea foam deep creep into the carbs while it's idling to make it run smoother/start easier

spray some, rev it slightly, spray some more then kill it, repeat....then change the plugs after it stops smoking.

seafoam is the schat.....for anything with an engine

cool deal, thanks guys
