I am new in this family... I have a 1977 Haskell w/ 454 panther. What happens if you run the engine without being in water? other then overheating if you run it forever I mean. Is Panther jets really as bad as I was told by a boat shop mech? I switched from points to a DUI and thats it... boat completly stock with the exception of a blueprint rebuild to the jet... Bought from original owner with orginal sale receipt and add for the boat. He never even rebuilt the carb, but the boat runs great. It was a garage queen since purchased that hardly saw use except upkeep runs... any help I would appriciate... New to the JET boat scene... worked on Mercs... when in the Navy... and saddly that is all I know...
