I am a second year boater and I bought a 1989 VIP Vantage with a 4.3L OMC Cobra in it last year. Sometimes it got up and going just fine, and sometimes it would just all of a sudden cut back to idle while going full speed...wouldn't stall, just cut back to idle with the throttle still wide open. I had plugs, wires replaced...points checked, carb. adjusted, etc. lately it will not even get up on plane and just goes along with the bow in the air at about 15 mph while wide open! I did notice that after I replaced the belts and tightened them up real good that it didn't do this (for a couple days) now it is back to not getting up on plane! I am going to try to re-tighten the belts and clean the carb. and flame arrestor. Any other ideas what this could be? The guy I bought it from said he gave up on trying to figure it out! I am guessing fuel delivery or something like ESA module???
