"I have a 1990 Silverton 34C with two 454/350hp Crusaders. The week-end prior to Mother's Day week end I ran the boat everything fine fuel consumption per floscan was normal. The Monday after Mother's Day, my wife and I left for a nine day cruise out of lake ponchatrain into th e Gulf of Mexico along the Mississippi Gulf Coast. As so as I fired up I noticed excessive fuel being used by my port engine.Bottom line I shut down that engine and continued on with one engine. I was traveling with a Trawler so no problem keeping up. I only used the engine when docking. When I got back I pulled both Quadrajets and had them rebuilt. Both were dirty and very cruddy. Put back on same problem. Changed plugs in both engines prior to trip, then changed plugs in port engine before restart with rebuilt carb. Swapped carbs on engines same results. Floscan shows 4-5gph at 650rpm on port engine 1/2 gph on starboard engine at same speed. I am a maintenance troubleshooter and have bee since 1968 and can usually find the cause of a problem, but guys this has me stumped. I found this forum by accident, did some reading and there is a great wealth of knowlege here. I hope some one can help solve my problem. THANKS"
