Thanks guys. Yes Bill, I keep the 5M/2 and 7M/2 (5 and 7 port) engines in stock.
 
You can find a lot cheaper motors in the nova Rossi car motors as well car racing is a little different but some of the car guys told me the 7 Port kangaroo motor was the best motor they ever built and they're getting back to that. I like nova Rossi's machine work but I hear new OPS 21 is whooping on them we will see I'll be playing testing both as well is trying to build K&B something that will compete. I would love to see any American business put out quality American products again.
 
Robert S,

The torque curve and demands on a competitive marine engine compared to car engines are different. Add this to the high nitro we burn and extensive testing is required to fine tune any marine engine offering. Thanks to dedicated boaters like Kentley P, Martin T, Aaron A, and Jerry C, their testing amd feedback helps Novarossi Italy stay ahead of the competition and on task for fine tuning and adding even more marine engines to the arsenal. Competition is ever present in racing and helps everyone step up their game.

Ron, what is the performance difference between the 5 and 7 port engine? Im looking to replace my well worn ol CMB LS motor thats in my 20 Seaducer SD3 mono....the 5 port I have in in my 20 Hydro has been just a GREAT all around motor for the money! By the way, THANKS guys for all the help!

Bill,

I have guys that swear by the performance of both motors, so whichever one best fits your budget will be a great choice. I also have the 21 headers and pipes available. Let me know if you need anything. Thanks.
