I Have Recently Purchased A 1998 370-ac With Twin 7.4 Mpi Mercruisers 550hrs They Seemto Run Great But Boat Is Quite Sluggish And Starboard Motor Does Not Want To Stay In Sync With Port Over 3000rpm Could This Be A Problem With Props Or Is This Normal For This Typeof Boat? Would Like To Takk To Other 370-ac Owners.

I used to have a '95 370 Dancer. When you say "sluggish", are you comparing it to anything else you might be used to? The 370 is a relatively large boat for gas engines, but they should be adequate to push her. What's your typical cruise speed? Have the props been overhauled recently? Is the bottom clean? Do you have a Glendenning or are you trying to sync manually?

Had a similar problem with my 37 and the long story short on that boat was spark plug wiring harnesses. For some reason they only lasted about three years and I replaced them at every other spark plug change. That boat ran fine but was rough on plugs and harnesses.
