Oil tank placement between stringers

[Capt Terry]

Although I dont have any photos, if you are interested in my approach I could provide some. In my ‘76 Seafari I basically added a horiz platform which seats on top of the center/keel stringer and extends towards ghe port stringer. This required an access hatch thru the splashwell, but provides storage under the port jumpseat.

Thanks, Terry:

I already have a hatch in the splashwell, which I use to access the bilge pump, inside-mounted transducer, and fuel filter. So I don't think the tank can go down in that space too. I have a second, house battery mounted inside my port locker (which was set up as a cooler when I got the boat. I would like to keep the oil tank in the starboard locker if possible.

Sailor-
FWIW here is what I did in 1985 to my '76 Seafari when buying a new Merc with an oil tank. I glassed up a 5/8" plywood tray and glued it down to the centerline stringer and the hull with some polyester resin thickened with cabosil; been there ever since. A few years ago used it to attach another bilge pump. The tray freed up some volume under the stern jump seat.
