Gas smell concern by new boat owner of 2006 Bayliner 175-gctid372925

[Guest]

Just bought 175br. Haven't had it in water yet. In my garage with cover on it, it gets very gassy smell. I just filled the tank, can't see any leaks....normal or should I be worried? Thanks for any advice to me as a never-before boat owner.

Relatively normal for a boat with carbureted engine. If I leave mine parked with the cover on, I smell gas fumes too. I've had the boat tore apart looking for a problem, but alas, nothing was ever found.

The smell is coming up through the carburetor because, well, that's where the gas is.

Make sure you run your blower a full 5 minutes before engine start and always do a sniff test. If you still smell gas, don't start the engine.

I have had a lot of boats with carbs and I have never had that happen.

One place you might check is the fuel tank vent hose. Is it connected?

I also have a 175 in the garage with a cover on it. When I lift the cover I also get a little bit of a gas smell. It got me concerned initially but could not find the source. Its been that way for 6 years and no issues so far but I do use the blower every time for several minutes before I start it.

I really appreciated the quick responses. Thanks for your advice. All others who may have advice, thank you also for posting.

I had a new 2010 185BR. It had the same minor gas smell when I had the Cockpit and Bow Cover on. As other have said use the blower for 5 minutes then start the boat. The smell shouldn't be extreme, but should have some gas smell. If it is extreme then you have a leak somewhere.

Another thought. Is the cover over the gas tank vent?

It could be that since you just filled it and now its in your garage that you may have over filled it and its warmer in your garage. The gasoline expanded and some came out the fuel tank vent. Also yes a carbed engine can have some has smell but shouldn't have excessive gas smell. Always be sure to run you bilge fan before starting for at least 5 minutes before turning over the engine.

You should avoid filling the tank to the top. You may have fuel in the vent hose or expansion issues as the cold underground gas gets hotter while sitting in the garage. As others said, take it out, run the blower, sniff the bilge, and decide from there.
