My wife and I sail a 2007 Beneteau 423. It is docked at Greers Ferry Lake AR, near LIttle Rock. Our retirementment plan includes cruising from the east coast through the islands in the Caribbean. I have had to replace fuel injectors already, with only 109 hours on the engine. I now have a problem with starting the engine. Turn key, exaust fan comes on but the starter will not engage. Possible fuse or wiring problem. Has anyone had similar problems?
