The stainless steel fuel vent cap with the screen mesh on the hull of my Whaler (2002 Ventura 210) is getting some serious pitting and greenish corrosion/powder. It seems too far gone to just buff and shine out, so I want to replace it. I have not tried to unscrew or remove it yet because I am not sure if this is the correct way to remove and replace it. I do not want to pull it off the hose in the back portion, I just want to replace the visible stainless steel cap with the mesh. Is it as simple as unscrewing the old one and screwing on a new one?

It is, by the way, the only corrosion in a year and a half on owning this Whaler....It is kept in a salt water slip yearround with Micron CSC ablative paint, and the bottom job still looks brand new! I think it is corroded from all the salt water spray that got on it, and I may have failed to rinse off all the spray at the end of the day.

For anyone else interested in Lenco tabs, I installed them this springtime with some zincs on them as well, and I have had nothing but good things to say about them. They were the best addition to my boat in the last year. The zincs do need to be replaced though. Almost 275 hours on my 2002 Optimax 200 and not one blip of trouble...just routine maintenance, Optikleen, and Optimax oil!

blavid,

Your fuel tank vent is a one piece unit; either with a straight or 90 degree fitting. Your vent is probably chrome-plated brass or bronze...I have never seen a stainless vent. The cap does not screw off and if you want to replace it the entire fitting must be replaced.

This is not a big deal IF you can get to the back of the fitting and remove the large 1" nut holding it in place. If you have the straight fitting, a 1" deep socket will remove the nut after the vent hose has been removed. If, on the other hand, you have the 90 degree fitting getting the nut off can be a real nightmare since you must use pliers to get to the nut.

I recently replaced the tank vent on my 21 Walkaround and had to first cut a 4" diameter hole in the fiberglass liner opposite the fitting to even gain access to the vent. Mine had the 90 degree fitting and I ended up cutting the tubing off just in back of the nut with a Dremel tool. I could then get the 1" socket on the nut. I replaced the vent with a straight one and covered the hole with a 4" inspection plate.

The vents on my 03 Conquest are pitted after 6 months of use. Seems Whaler has changed vents and went to a recesed vent for the 04 Models with a larger screen diameter. If you're going thru the trouble of changing vents I suggest that you contact Whaler for the Vendor & model of the current vents. It appears that the the thru hole may have to be somewhat enlarged. I don't care about the pitting, but the screen mesh is over 50% clogged up with salt residue.

Since you may recall I had an 01 21' Ventura, that boat had the same pitting/clogging issues as my current 03.

Thanks for the tips! I went to West Marine and saw some fuel tank vents....it MAY be a big deal if I can't get to the back of the hose fitting! I haven't been down to my marina today, so I can only guess as to what the access will be like to the rear of the fuel vent. Maybe I'll have my dealer take a look?

I found a website (www.allaboutboating.com) that had some 316 stainless steel fuel fittings. Mine appear to be chrome over bronze; maybe that is why they pitted so badly?

I like the idea of maybe using the 2004 flush mount fuel fittings if I can get my hands on one of them. Like TRAFFICLAWYER, my screen on the fuel vent is starting to get blocked off.

just call Whaler customer service and ask them for the model & vendor of these new flush vents.

Thanks for the tips..I emailed C. Bennett at Whaler.com and here is his reply:

The Whaler part# for the recessed vents used on the 2004 210 Ventura is 1754881. They can be ordered (and installed) through your local Boston Whaler dealer (sorry, no factory direct).

The original holes would have to be enlarged to accept the newer style
fittings (going from 3/4" to 1 3/8").

For more information on the Orcas Marine Products vents, check their
website...

I will see if this is an option!

blavid;

The hardware is nice quality, I liked the flush vents but for now I'll get a tootbrush and some salt-away and clean them. I have 2 on my boat, gas~head. Let us know how you make out!

There may be others but both TACO and Sea Dog make stainless steel tank vents.

Perko and Attwood are at best chrome plated brass, more likely chrome plated zinc.

The Sea Dog part numbers are:
Straight 352210-1
90 degree 352230-1

I don't have a TACO catalog here at the house so I can't come up with their numbers.
