Hi, I'm new to the forum. Just bought 89 Pirat without engine and gearbox. The boat is waiting in the store for new stringers and I am finishing the driveline. I have a 7.4 MPI engine for it and I miss the gearbox and the bell. From what I can see there are 3 direct drive gearboxes specified for this engine. So my question is which one should I go with. 71c has a smaller 4 "flange and 72c is 5", I don't know about the ZF 45c. The 71c is also shorter as per spec, so I really don't know if the 72c fits. What was the original gearbox on this boat?
I am from Poland and the knowledge of Supra is very little, so please help.
