Got a 1994 Nordic with a 502 efi. Not sure of its a Venture or Scandia. Boat measure about 24 ft. Boat has been sitting for years. Bought it from the original owner. had 86 hours on the meter, only 30 something hours of actual running on ECU. It will run 74 gps with a 23 three blade @ 4950 RPM. Anyone out there have any suggestions on how I can get her up to 80 without breaking the bank.
