Gas Smell
Could it be just the gas in the carbs that I’m smelling?
I’ve let the blower run for 30 minutes or so after shutdown which I think helps a bit. I plan on idling 1 engine at a time to try and isolate which side it’s coming from. 85 Mariner with Crusader 220’s.
Thanks

Re: Gas Smell
Also most humans can smell gas fumes in very tiny amounts PPM, so it really does not have to be much of a leak.
Is this something that just started or been getting worse. Be very careful while you look for the source of this.

Not after fueling. I’ve looked at fuel fill lines and vent lines and don’t see visible gas/moisture. Poked around fuel lines to the carbs and don’t see much.

In my prev boat,gas powered Carver 396, I smelled gas initially after filling (course that was over 10 years from new), but it continued to get worse so even after running the boat, I could smell it. Turns out the fuel fill lines needed to be replaced. If you don’t see a leak in a tank, I would bet it’s hoses and as Bud37 said, you typically can’t actually SEE the issue in a fuel line unless bent.

I will check that tomorrow.
