This Suzuki 90hp I bought from original owner who bought it new and he took it in meticulously for services I replaced impeller and both thermostats and rebuilt all three carbs,compression is 125psi exactly on all four most likely not to far off new.Im either putting it on one of my two boats or selling separate just need cash to keep on building You can have the motor tested by professionals at your expense I will start it up for you,check compression for you shift in and out of gears This is also a oil injection motor No mixing gas just keep oil reservoir full.
