Hey everyone, not sure why I didn’t join this earlier lol. I have a 2003 Stingray with the Volvo Penta 3.0 GSP-C engine serial #4012071814. Last year while I was troubleshooting a bogging down issue when giving the boat full throttle I was replacing everything under the sun that could be an associated problem with that. Carburetor had a fresh rebuild kit so I knew it wasn’t that. So I bought new plugs, wires, distributor cap, ignition module and coil. And while none of that fixed my issue which I eventual can only contribute to be some shitty gas I got (of course 100s of dollars later). At some point a new problem occurred. Then engine on this boat is running the best it ever has. But now at any given time the boat will die. Could be at any speed or giving the boat a little gas in neutral on a cold start. never at idol. The boat WILL NOT start by putting boat back in neutral then turning it over while still in the run position. You have to turn key to OFF and then turn the key and it will start instantly every time. I have replaced the ignition relay as well as the ignition switch. I removed the SEND grey wire from the tach and still have the problem. I don’t think it’s my kill switch because that kills all power to the console and engine when I remove lanyard. I’ve checked all my wires for loose ground or faulty connections and can’t seem to find any. When engine dies I have 13.5 volts on all 4 wires at the coil (grey purple brown pink). Not sure what is killing this boat but its slowly killing me lol. Im leaning toward shift interruption switch but I cant find one on any of my manual diagrams. Thanks for any help
As a side note, when I was troubleshooting the hard acceleration issue I was checking timing and when I went to use the timing shunt, the engine never shunted or retarded down. Not sure about that and it wasn’t shunting down before I replaced the cap and rotor.
