    Surging / losing rpm

    Okay I know I’m super late but I still have the exact problem. It still has the random cut out sometimes it’s very often sometimes it’s further between but taking it in by myself the other night it cut out twice and completely cut off. Then fired right back up and continued to cut out randomly...

    Can you explain further. Are you referring to the kill switch next to the driver seat or something else. If so what do I need to be looking at.

    Surging / losing rpm

    That’s what I’m thinking a bad wire somewhere. I’ve done changed everything else. I was gonna pull the wiring harness next. I did check into the shift interrupt switch. If you manual tap the spring by hand It recreates the exact same rpm loss but I don’t see the switch being bumped while driving.

    Surging / losing rpm

    I’m sorry I’m new to this. It is carbed. It’s my first boat so I’m not super familiar with it. Im learning as I go. I can get a vin number. But I just bought new NGK BPR6EFS spark plugs. It did have ac delco I think gapped at .40. And the picture is what I mean by a computer.

    Surging / losing rpm

    Hey this is my first time on here but I have a 2001 bayliner with a 5.0 mercruiser. It will randomly lose rpm and jump right back up. The boat will pull back a little then speed back up. I’ve been chasing this problem over 2 years. Sent it to many mechanics and tore it down twice. I will attach...
