Author Topic:   Gas smell in Nantucket

While uncovering boat this spring I opened rear deck hatch.
There was a very distinct odor of gasoline in space below deck. I lt it air out thinking it might be the vent and it had been stored all winter. After one short cruise on river and a week storage again I smell gas down under rear deck. Not enough to cause explosion (I think)but troublesome anyway. Anybody had same problem and any thoughts? Going to call dealer,yes.

I believe that the Nantucket has the same polyethylene (or is it polypropylene?) tank as the Dauntless series boats. These tanks seem to be pretty well known for allowing a gas odor to permeate out of the tanks. Whaler made a small design mod on the 160 Dauntless to add small vents aft of the quarter seats to help dissipate the odor. You should look into this more carefully and make sure none of your fuel lines or fittings are actually leaking, but odds are it's just the nature of the tank. I store my boat with the console door open, maybe it helps a little, maybe it doesn't.

Same problem on my Nantucket. I took it too my dealer and they told me that other Nantucket owners expressed the same concern. They put a fuel sniffer on it and assured me that it was well within safe limits. Checked the tank and it has NO leaks. It supposed to be that with all plastic tanks there will be some fuel smell that is not dangerous, due to migration through the plastic itself. I called the tank manufacture and asked it this was true and they said it was and not to worry. I have seen this concern expressed by quite a few owners of other brands of boats with the same type fuel tanks and they were told the same thing....just the nature of the beast and it not a problem. That said...I would take it too your dealer and have them check it out ASAP, just to be on the safe side!!!!

Thanks for the explanations. Will keep a nose out for any increase. Have had chat with dealer just to keep a record going. Suppose bilge pump motor and its switch are sealed to prevent water ingress so should not ignite fumes.

I have a 2004 Dauntless 160 and it too as the smell. So if they fixed something it must have been this year. Did not seem to be too strong, but then what does that mean. I will make a habit of airing it out before turning on the electronics.

Yiddle Its a 2004 Nantucket. Dealer checked it out last fall and found no leaks. Didn't notice much smell while using boat. When uncovering it this spring it was apparent when I looked into bilge. just have to air it out after some time of no use.

I have the Dauntless 160 (2001) with the retro-fit vents in the console. It still smells, but only after being covered.

To clarify, my Dauntless is garage kept so while not covered, is out of the wind. I suspect if it we're outside in the wind, uncovered, I would not have the oder. There is some verbage in the manual about checking the venting system regularily for continued safe operations. Access to it is through a twist-out plate inside the cockpit. I'm not sure what the Nantucket has, but maybe similar. Going down this weekend so I'll check it out although my boat is new so not sure why it would already be clogged.

Yiddil, interesting...that you don’t notice any gas smell in the beige? I have a 2004 and thought you did too. I would think we have the same tank. I understand the migration through the tank, but if you don’t have the smell it makes me even more uneasy. Given the explanation I got from BW make me wonder if that’s the entire problem. Next time you’re in the boat, please pull the aft access plate and give it a good whiff and let us know what you discover.

This thread clarifies my comments about the 160 Dauntless aft vents. It appears that they were added in the 2003 model year, although no catalog (up through 2004 anyway) shows them. The thread also discusses a design change to the fuel filler and tank vent.

Another discussion on gas smell can be found here, with skred documenting his discussions with Whaler that it is a normal side-effect of the plastic tank.

Finally, here's one with no less of an authority than Tom W. Clark chiming in...

(love that new search engine!)

Whalerider... I was down to "Das BOat" Today and checked again....I have no such smell coming from anywhere in or around my 2004 Nantucket...I am still very suprized to hear or this malidy!! This is the first time anyone has said anything about them nantuckets...Yes, Mines a 2004...w 115-2...Ive boiated with Marlin, so I knew about his Dauntles16 vents and the gas smell...and as I recal, re checked mine out to see if it smelled...but alas, nothing...and that was last summer...

I think the threads Marlin gave you speak volumes...

I still think you have nothing to worry about as long as your bilge is clean and dry............let me know if you have any other considerations...

I too noticed with my 2004 Nantucket a gas smell when opening rear deck hatch. At 30hr service dealer check'd this out at my request, I think they pressure tested the fuel system...answer - just the way the plastic tanks smells.

I was out yesterday morning, and this thread piqued my curiosity. I did not smell any gas smell. However, when I was filling up with gas, the attendant asked me where my gas vent was. I have to check the manual.

SalA..its part of the main fuel fill. Open up the twist off plate by the fuel cap and it will become obvious how it’s plumbed. Bet you have already discovered that though.

I smelled the gas yesterday when I opened the rear deck hatch. I checked all the fitttings and they are all tight. My boat is goin in for a checkup 6/28 so I will ask Pete Reils to check it out then as well (Pete if you read this please make a mental note to check it out?)

The same smell is apparent in my Nantucket. I have some experience with these type tanks/material from other applications and yes you will find a smell of either gasoline or the chemical in use. It is normal and I bet I could smell it in Yiddal's Nantucket. My wife cannot smell a thing including the gasoline smell but I can and it is there but I have no concerns for it. It would help if I left the covers and access ports open but I don't to keep pesky critters and dirt daubers out.

Same thing here on my tucket, dealer says small amount of fumes coming through tank. Bilge pump is sealed so hope no explosion will happen. I always leave hatch cover open when putting away after use. Don't smell anything when underway.
