Old Bayliner - Needs a New Fuel Tank

I have a 69 17' Bayliner with 120 Mercruiser I/O.

She wouldn't start this Spring and after checking the carb fuel bowl there is rust in the gas. The tank appears to be steel which is stowed in the bow forward on the helm. It is shaped to fit the bow and near as I can calculate is about 17 gal. capacity.

Looks like a relatively easy replacement. Just have to drain the tank, get the seats out of the way, unbolt the tank tiedowns, fill tube and vent tube connections and drag it onto the deck inside the boat. Then hoist it out.

How important is it to have a tank that large? I was thinking of getting a 12-13 gal replacement. The tough part may be finding a tank that matches up to the filler tube location.

Any suggestions? Am I overlooking something important. Did I cause this rust some way or is this the typical demise of the old tank?

Yeah, I know, shes really old. But I find enjoyment in bringing old cars back to life. Doing a boat should be fun also but it is new to me.

Thanks for reading!

I can burn 10-12 gallons in 2 hours on my 19' 120HP. On your 17' you may get a little better but I would stick around a 20gal or so.

Re: Old Bayliner - Needs a New Fuel Tank

There are many companies out there that will build you a new tank to order. Your tank sounds similar to mine. I had one built, complete with a sender for just under $300. They can use your tank for the template or if they are not local send them a detailed drawing with the dimensions and a few photos. A good tank is a must on the water. And yes, tanks that old can get corroded in the years. I would also replace all the hoses too (fill, vent, feed) since they dry rot.

Re: Old Bayliner - Needs a New Fuel Tank

Made a trip to the Tacoma water front today and an old salt in a boat repair shop down there pointed me toward a company in Bellingham WA that builds custom marine fuel tanks.

I sent them an email for a quote.

Thanks for the tips!
