SILVER LINING IS FINALLY HOME
Posted: Thu Mar 14, 2013 4:55 pm
Hi All,
I have finally moved the Sivlerton 37 to San Diego, with weather and an ongoing fuel issues the move kept getting pushed back and delayed. the weather finally cooperated and I got the boat moved to San Diego, but not without events. I left Mariana Del Rey this past Sunday headed for two harbors Catalina Island to get fuel and set a fuel burn rate, I got just outside of the MDR jetty throttled up to about 1500 rpm and a few seconds later, she shut down ( I had already replaced the fuel pump on the starboard engine the previous weekend due to fact that the pump started to leak though the bypass)
I came back in to the harbor and it would run at idle but not at any higher rpm. Safely back in the slip I removed the Floscan flow meter and changed all of the fuel filters , I did find debris in the carb screen so I thought maybe the flow meter had jammed or plugged
Monday I headed out of MDR at about 6:30 am, she ran fine and off went, she ran ok at about 1500 so I ran that speed for about an hour, I throttled up to 1800 and she almost immediately died, it would restart and die, over and over, so I continued on to the isthmus on one engine. During this time, I removed the fuel hose to the carb, ran some clear hose I bought to a bucket in the cockpit, and cranked and cranked , but never got any fuel to the bucket… figuring the new fuel pump failed. The autopilot works flawlessly by the way
Once moored in Two Harbors, I went ashore and found an electric fuel pump and fitting, I bypassed the mechanical fuel pump and the boat started right up and ran fine (at idle on a mooring) That night (Monday) I woke up remembering stories I had read here at the TOFthat there is supposed to be an anti-siphon valve in a gasoline fuel system to prevent emptying a fuel tank into the bilge by a siphon through the carb. Tuesday morning, I followed the fuel lines to the tank and only found what looked to be an NPT to Compression adapter, I went ahead and removed the fitting anyways, which is buried behind the engine and exhaust hoses and below the floor. When I got it out and look at it, it was the anti-siphon valve and sure enough, it was completely plugged with debris. (see photo) I cleaned it out and the boat ran great for the rest of the trip, so here is a concrete example of a lesson learned on this forum! As you an see, I spent a fair amount of the trip running in low visability and fog, ---RADAR----GPS Plotter AUTO PILOT ....dont leave home without them!
here are a bunch of photos of the trip...
