I have 1996 Glastron boat with a Mercruiser 3.0 engine.
Last year, I had issues with debris in my boat’s gas tank that was causing my pickup tube to clog up and stall the boat. With all of your help, I diagnosed the problem by running the boat from an auxiliary gas tank. When I ran the boat with that tank, and took it out on the lake, everything was perfect.
I cleaned the debris out of the tank and install a new pickup tube and fuel sender.
Since then, I’ve started the boat a few times. It ran a little rough at first, but when it warmed up, it ran fine. However, I had not taken it out from a run on the lake.
In the last couple of months, I’ve started it and it ran fine, but I still hadn’t taken it out on the lake for a run.
Last weekend, I started it and it ran fine at high speed and idle. So, I decided to take it out on the lake.
Things started out fine, but within a minute or two, when I tried to turn the boat, it stalled and I couldn’t restart it. It sounded like it wasn’t getting enough gas. I tried to start it a number of times, but I just couldn’t keep it running. Finally, when I got it started at a high RPM, I kept pumping the accelerator real fast and it would keep running haltingly. I was able to got it back to my dock with that method.
Once I got it back to my dock, I replaced the carburetor with one that I had rebuilt. That made no difference. It acted the same as the original carburetor. I bypassed the water-fuel separator, but that made no difference. I ran the boat from the auxiliary fuel tank and no difference. I replaced the filter on the fuel pump and still no difference.
This week I installed a new fuel pump and no difference. I removed the gas cap, and that make no difference. I ran the boat from the auxiliary tank again with new gas and some Sea Foam and no difference.
The boat will start and run at 2200 rpm, but when I lower the engine speed, it stalls out like it’s not getting enough gas.
I’m thinking of rebuilding the original carburetor and reinstalling it.
I’m at a loss, and don’t know what else to do.
Thanks in advance for your expertise and help.
