I HAVE JUST INHERITED TWO GAMEFISHER OUTBOARD MOTORS, ONE A 9.9 H.P., THE OTHER A 15 H.P. THESE HAVE BEEN LAID UP FOR ABOUT TWO YEARS. I MANAGED TO GET BOTH STARTED, THE 15 HP PLANES MY 18' SEA ARK WITH NO PROBLEM, THE 9.9 JUST WILL GET THE BOAT ON PLANE. I PULLED THE HEADS OFF BOTH MOTORS AND THE CYLINDER BORE AND THE STROKE IS THE SAME ON BOTH MOTORS. IS THERE A PROCEEDURE I CAN PERFORM TO MAKE THE 9.9 INTO THE 15 WITHOUT A COMPLETE REBUILD. HAS ANYONE HAD ANY EXPERIENCE WITH EITHER OF THESE MOTORS? DOES ANYONE KNOW WHO BUILT THEM FOR SEARS. BOTH OF THESE MOTORS ARE 1995 YEAR MODELS AND BOTH HAVE ABOUT 50 HOURS OF USE ON THEM BEFORE THEY WERE LAID UP. OLD HENRY DIED LAST MONDAY AND HE TOLD HIS WIFE TO GIVE ME THE GAMEFISHERS AND THE SEARS FIBERGLASS BOAT WHICH IS A 14' AND IS HEAVY AS LEAD. ANY INFORMATION ANYONE CAN GIVE ME ON THIS WILL BE GREATLY APPRECIATED.
THANKS IN ADVANCE FOR YOUR REPLIES.
