I am perplexed! My boat is a 1996 Sundancer with a single Merc 7.4 EFI bravo 3.To make a looooong story short. I had a mechanic whom I have used many times replace the gimbal housing. The engine had to come out. After I got her back, she ran ok, but on one particular day she was running at about 3300 RPM when she just dropped to under 1000 RPM. I put her in neutral and the idle was jumping like I was revving the engine. I took her back and had the fuel regulator replaced. Now she won't start at all unless I spray ether into the flame arrestor. I have a new VST tank, have cleaned the injectors and a new IAC sensor. My mechanic is telling me the fuel pressure is fine and there is a spark at the plug. Once started it runs OK, but it will not start without the ether..period! All other codes are clear. Any opinions?
