I have a running 88 Gt 150 for sale. (J150STLACA)
Motor has been good to me, but re-powering.
It is currently still rigged on the boat, and we fish almost every weekend.
I wast told Cylinder #4 has a slight scuff. (seen by scope), but still has good compression #'s for this model. I could possibly have either a stator or power pack that might be going bad, just haven't narrowed down which one yet. All in all, a good motor for the year. The vintage styling of these things never gets old.
All reasonable offers considered. Also may be interested in parting out.
