We've got a 225 Mercury OPtimax, pushing a 22 foot Boston Whaler. 25" shaft. Less that 60 hours on the engine, running proper Merc Premium Optimax oil. 122 gallon tank, about 50 gallons of last year's gas, 70 gallons of new gas.
Ran fine last fall. Good out of the hole, top RPM about 5,600. No prop change. We took it out to prep for the season, and now it takes about 2 minutes to pull itself on plane, and only draws 4,800 WOT.
Before I haul it to the Merc Shop (where it will sit for 2 weeks before they can get to it) is there anything I can do to check it out?
Separator filter?
Sucking air?
Plugs?
It's still under warranty.
Thanks in advance.
