With previous boat we had a stalling issue when slowing or throttling back. Yanmar would run all day if need be and as soon as approaching a dock or mooring, would stall. Spent days trying everything. Filter changes, tightening hose clamps, changing crush washers.... turned out to be sludge in the tank. The pickup tube was in the forward end of the tank and would clog when slowing. Cleaned the tank, no more problems. Other than the yard that cleaned the tank did so with gusto and put a hole in the tank. Which needed replacing. Then there was the explosion that occurred when they inadvertently cut through the propane line (which was obscured by insulation) While rerouting the tank vent.......but it ran like a top until then. > Jon
