hello, i am a new user from germany, please excused my bad english
I drive a 1989 cougar us1 38 with 2x mercruiser 7.4 litres and supercharger.
The engines horsepower ist circa 490 hp. The exaust must be closed, because if it is open i cannot drive in germany with this engines my boat runs about 68 miles....
Now i want to change the 7,4 litres against 2x mercruiser 496 mag ho with 425 hp.
