I have a 2005 33 SS with Crusader engines. My starboard engine is giving me fits. It will always crank but sometimes wont start. When it does start it runs perfect. The other day my wife was on the bridge and I was in the engine room and it wouldnt start. I noticed the breaker in the engine room (70amps) was tripped.....I reset it and it started right up. Now its back to its old tricks again but the breaker hasnt tripped. When you turn the ignition key you hear a faint beep beep and then the loud engine alarm as normal. The faint beep beep is a new noise. My boat is maintained meticulously and super clean in and out. I cleaned all the battery connections and took all the breakers apart and cleaned all those connections. Do you think it could be an ignition switch?.....it is fuel injected and electronic ignition.
