Hi all. I’m desperate for help with my 1997 sea ray 270 Sundancer, single 7.4 in Baltimore. My father and I have spent 20+ hours over 5 months trying to get it to start.
There is power going to the coil, but nothing coming from the coil. We have replaced the coil. We have bypassed the neutral safety switch in the throttle. We have grounded out the coil. The batteries and battery charger are new. I replaced the distributor (not getting power anyway) and most other normal parts. We tested the ignition and traced the neutral safety switch wires as far as we could.
I last fired it up in June and once I pulled out of the slip, it shut off. You can crank it for hours and hear bubbling noises from the stern drive but it will not fire. There is definitely gas in the carb.
We have been through the mercuiser manual twice and checked all the water temp/oil pressure sensors by shorting them and watching the needle flip.
The one issue I found when the boat shut off in June is that an audible alarm sounded that would only since by turning off the red ignition switch on the throttle. I finally got that alarm to stop sounding when I located a wire that came off the automatic choke.
Does anyone have any suggestions? Our last hope is that one of those little control modules mounted behind the motor, around the risers may be bad. There doesn’t seem to be a way to test them and they may be hard to find replacements.
Any help is much appreciated. My father is a mechanic but has never dealt with boat issues like these.
Thanks in advance.
