Re: The only thing I didnt do...
Hi,
fuel stabilizer is intended to be used for the carburetor/fuel-injection system. The tank is ought to be full to the brim with gas to avoid rust.
Your OMC has a carburetor, so it is not that bad. Would be more difficult with MPI-Engines. You should not have any problems. For how long haven't you used your boat?
