How do I change the carburetor jets on my new Mercury 4hp 2-stroke outboard to get 5hp out of it. Also what is part number needed. Not concerned about warrentee if it works.
Hi, AWACS.<br /><br />As MY says, 1hp wouldn't be noticable.<br /><br />More important, changing the jets wont give you 5hp, it will give you a terrible running 4hp.
