Looking to see if I can get some help.. I have a 2000 ski centurion (mercruiser motor, carb), I recently had a season service completed (fuel separator, filter, ATF, oil, impeller and compression test). Let me back up, prior to having it serviced, the boat ran great... Once I got it back from the shop the boat did not run under load. It fired up and ran in idle and neutral completely fine. After taking it back to the shop the boat runs but cuts out and picks it self back up occasionally. Apparently they told me I'm over pressurized on my carb (11-12 psi). Here's my questions:
This sounds like it could be an electrical or fuel problem. Has anyone ran into a similar situation with bogging out and picking back up under a load? I don't think it's a fuel pump, but maybe an anti siphon valve or something. Could it be ignition problem... a bad coil?
Thanks
