Fuel Line Issue??

We were on the water in our 2022 L22 with a 200 Yamaha, and things were running great with 30% fuel showing on the Simrad when the engine sputtered and quit. The engine wouldn’t turn over and we had to be towed in. It was as if we ran out of gas, but we weren’t. Back at the dock, I added 5 gallons of gas, but the engine still wouldn’t crank. Pumped the primer bulb to death but it never got firm. Makes a sound as if air is in the line. Clearly, gas isn’t in the line. Is this a DIY fix? Any thoughts or ideas? All would be appreciated!! Thanks in advance.
 
When you say that the engine would “not turn over” was it cranking or nothing at all?
 
Others on this site have more expertise, than me but if it will not crank / turnover, I would start with electrical.

I had an issue once, and just cleaning the battery terminals with baking soda fixed the problem and they didn’t look that bad.

I would also check all the fuse / breakers including those under the engine cover. Start with the easy stuff first. Are the batteries good? Could we have a charging issue and the batteries went dead? Any loose wires, etc.?
I would move to fuel only after making sure the engine is turning over and I had spark activity.
 
Good insights. I’ve tried all of the fuses and such. Batteries are good. The boat was running fine and just quit running mid-cruise. It’s as if it ran out of gas, but gas is in the tank. The fuel line is empty. Wondering how to check for a clogged line or issue with the sending unit or filter. Hoping someone here has an idea! Thanks!
 
Ok - so your volt meter says the batteries are 12.2v, ideally 12.5 or higher. All other electronics working I assume. You have checked the battery compartment for loose wires or connections, including the fuse block. Also look for in-line fuses in the battery compartment and test that they are working using your volt meter. I have read a few posts where the kill switch goes bad, or a wire comes loose - no idea what it takes to get into those too test. No cranking = clearly not a gas issue. Hope that helps a tad.....
 
Would these fuse/electrical issues cause it to stop running in the middle of a boat ride?
 
I had something like this happen to me on my 2025 25RFB. It had been running great all summer. Went for lunch at a restaurant on our lake. Came out after lunch and engine wouldn't turn over. Trim wouldn't work. No lights on the throttle. All other electronics worked. I looked at all the fuses and everything looked fine. I saw an inline fuse for the engine in the back by the battery and unplugged that and it look good. Plugged it back in and tried to start. It started. The rest of the day everything worked fine. A day later, went to go start and the engine wouldn't turn over again. I unplugged that fuse again a few times and still wouldn't work. Tried like a 5th time and finally the pontoon started. It must be something electrical for sure. I pulled my pontoon for the season so I will have the dealer look into this.

Glad you got it sorted. Reading back through this thread, I think there was some confusion that took some folks down the wrong diagnostic path. To most of us, "cranking" means the starter is engaging the flywheel and moving the internal components of the engine. If your root cause was a chewed up fuel line, I would have to think your motor was cranking, just not "firing."
 
I hate you had that happen. I've had squirrels chew a hole in my bimini boot, chewed on the seats (not bad thankfully), and chewed the wires out of my boathouse. After an eradication program I enacted, they pretty much stay 2 houses away now. Squirrels are just rats with a good public relations program.
