I replaced the gas tank on my 1975 C27. It was in the rear quarterberth. I replaced it with a "temporary" 6 gallon Tempo tank in the cockpit lazarette, plumbed to the A4.
If you do that, keep as much weight forward as you can -- the extra weight in the stern can make it squat a bit. If the bow rises up a few inches, the ability to sail up wind will suffer because the bow will blow off downwind.

I have a 1977 Catalina 27 in Lake Texoma near Dallas. It has served my dad and I well over the years but recently it has developed a slight leak in the gas tank - we have the original Universal Atomic 4 with less than 400 hours on it. Unfortunately, the estimate to cut out the lazarette remove the tank and replace with a new one is $3200 of which only $250 is the new tank itself. This would really be too much to spend on this boat so it may be an end of an era if I dont come up with something else. I was wondering if there was any brilliant advice, if any of you have replaced the tank before etc. Thanks so much Sam Jube II and Sam See what's new at AOL.com and Make AOL Your Homepage.
