Default 496HO short 350 rpms 35 Zr

Hello, My port motor is running 350rpms slow or behind the stbd motor. Computer scanner says everythong is good. Furl injectors are goong to be professionally cleaned and other filters checked. Any other ideas or experiences with this that the problem could be? Thanks

Those dumb .060 gaps used in 496 trucks got carried over to boats. Id start with with plugs with no more than .040 gap to start with.

Lower power could also be fuel filters ir even flaking cool
fuel module getting into injectors..

Try a different set of props or swap them for a test run. Just remember your controls will be backward.
