om606 into boat hp 250-300 how
hi guys i was just wondering i recently bought a om606 , i am fitting it to a boat and am wondering how to upgrade to between 250 and 300hp i have a manual pump of a 603 already so it can be modified to fit im told you can screw the power up on these to get more hp , any help guys would be appreciated.
Is it N/A or turbocharged?
