Im in the process of restoring my '78 Nordic completly. Im not sure about the jet drive. I know its a 12s model but I understand that there is a early and a late model. How can I tell, I have the complete model and serial #. Model MB-12-SA Serial 1220 Maybe someone can help me? Also what cut impellor should I get. Not sure on HP...300-400? 460ci, mild cam 9:1 comp. '73 heads tunnel ram intake W/holley 450's, MSD igniton. The hull dosent seem to be that heavy. 18 ft long. Im to jets and I kinda need a starting place to get in the right direction. Where would be a good place to purchase rebuild kit and impellor?

The serial number tells that it is the old style. No problem, they can be made to work just as well as the new ones. Give me a PM.

Yep, it's the early model, outlet is small. They don't flow well in stock form but can be opened up to flow. Just like porting and polishing heads. I had mine worked with good results. Don't have before pics but these are after.
