Pontoon Boat & Deck Boat Forum

So we took her out. Love the boat, all the room and storage is great. We have some kind of problem with the motor. Idles fine and will run slow but try to give it the gas and it bogs out. No take off or power at all. I'm going to check all the lines to see if there is a leak. Was thinking it could be bad fuel, don't know how long it has set up. Any things else you think it could be?

Other then that my dogs had a great time. I got 2 mini doxies and a golden retreivier. My two older dogs have been out on the river many times. The youngest doxie just had a grand time. He took right to the water and the boat. I got to get the problems solved and get us all back out there again.

Bad Fuel
Fuel Filter
Dry rotted lines
The primer bulb could be closaping
Plugs


Would be some basic areas I would check

What bruuuuce said AND

if that dont fix it then the carbs will need to be taken apart and cleaned, my 50 did that and i changed everything and finly cleant the carbs and it run like new

DONT let a lil setback discourage you fun.... THATS whats nice about a TOON is ya dont HAVE to go fast to have FUN LOL

Sounds like a bad accelerator pump in the carb. Rebuild it and you'll be fine.

HUH??? its a 40 merc


I didnt know they had a acc pump

Two other possibilities - inadequate venting on the fuel tank (try running with the fuel cap off to see if that helps) or a pinhole size leak in the fuel line allowing air to be sucked in.

Nevermind, I'm thinking I/O...wasn't drinking either. First thing I'd check though is fuel pressure and go from there.

Ok ya had me scraching my head for a min

How about running a can of Sea Foam thru it first, it should help to clean it out and it's cheaper than tearing things apart first.
Had a snowmobile last year that I had not run for two years. Ran like crap when excellerating. added a can of Sea Foam and within a couple hours was running great.

how old is the gas. if its old dump it and put fresh in if freash check lines and plugs.

I like the seafoam idea. I think you might have water in the gas. Another cheap fix is to add a fuel water separator kit to the fuel line. $20 bucks or so.

Great news called the dealer and complained so they are going to fix it. Should get it back before the weekend.

Sweet that's a helluva dealer on a used toon
