I have a 1998 outrage 20. I have run into a problem with a leaking fuel tank that needs to be replaced. Anyone out there replaced one or a similar boat. I'm contemplating tackling this job myself.I was looking for advice or lessens learned from anyone out there with experience with a similar project. Also what do you guys think would be a reasopable estimate to have this done by a shop? thanks in advance

Take a look at this thread. You might email the poster and ask about his progress.

Good luck,

A number of veterans here have done it themselves. There is a reference article on one of them.

Do a search and get ready for a lot of great reading.

thanks guys for the replys. Like a good BW student, I have read through the articles listed above. what do you guys think is a fair price to replace the tank by a reapir shop or professional. Also Ihave found the rubber supports for the fuel tank periodically in the bilge. which I'm assuming is the cause of a failure on a 9 year old tank.

I'm particularly interested in what the specific failure location is, since I have a 97 Outrage 20. I haven't found any of the rubber supports on mine in the bilge (yet). Have you pinpointed the leak orgin - just making sure it's not the fill or vent hose for example.

Under Reference the OEM manufacturer of the tank is Florida Marine Tank, 305-620-9030.

The price was $400+ including shipping (in 2002) in this thread about an Outrage 18 tank

I don't have any experience on a shop repair like this so can't offer an estimate.

rumrunner, I was hoping it was a fuel hose etc. when I first noticed the problem(I try to thinksimple first) however with the amount of fuel in my bilage( est. 30+ gallons) both my mechanic and I agree It is a tank issue. What I think happened is that the tank supports worked there way loose(do not appear to be fixed in place with anything) causing the tank to become loose and crack. This is strictly hypothosis and I will not know until the tank is pulled out of the boat.

casco bay, BW and other shops have qouted me about $1,500 for the tank(don't know if that includes shipping)

I was hoping that a few of the guys who have done this project would post. I will email a few of them off-line and try to get them to weigh in.

I think that until you do a leak-down test, you will not truly know if it is the tank itself.

Have you pulled the floor?

I would call the OEM vendor and get a quote. $1500 sounds high from what I have read.

By the way, if you are mildly mechanically inclined, you could do the replacement yourself. Is that an option for you?

CBO I will in all liklyhood do the job myself. It seems like mostly labor and disassembling and reassembling the Ttop, console and floor. My time is at a premium though, so I'm looking to having someone else do it. In the end I will probably do some or most of the job myself.

thanks, I ended up ordering a tank from Florida Marine. I'm in the process taking everything apart while I wait for the tank. So far everything is coming apart with out any major problems.

Take some pics as your work progresses, if possible. I'm curious to see what you encounter.

I was able to unscrew the floor and console. My oringinal plan was to try and leave the console attached to the floor section and just unscrew the floor section, to access the tank. I ended up having to unscrew the console in order to remove the floor section. The floor section lifted up pretty easy. Boston whaler originally just sealed the seams with silicon, but did not use any adhesive to hold the floor section in place. The floor section appears to be in good shape. compleatly sealed and dry, including all of the screw holes.
the gas tank is held in by brackets on the top of each side. The old gas tank lifted out fairly easy. once out of the boat there was a small approx 1/4" dia hole on the bottom of the tank. the tank looked in decent shape otherwise. there where some very small area of min. corrosion but that was it. Pretty much all of the rubber supports had come loose, and were missing under the tank. I have been taking pictures of the entire process, and will try to post.
