I think there are advantages and disadvantages to any setup but having the ability to switch which tank/tanks has access to would be ideal. Any ideas? . . .

Welcome aboard Brett! Sounds like you have the perfect boat for your location! I saw your boat at the local E-TEC dealer several years ago and told Carla about it, who told her dad, and he ended up buying it a couple weeks later! Too bad his health didn't allow him to hang on to it!

If I had a boat with twin engines and twin tanks, I'd definitely want to be able to feed either engine from either tank! Don't know what your fuel filter setup looks like, but I'm guessing you probably have a Racor-type filter for each engine. Most of those filters have two inlets and one outlet, so all you have to do is run fuel lines from each tank to each filter with a shut off valve in each line, and then either engine could draw fuel from either tank! If each filter head only has one inlet and outlet port, you could change the filter head to one of these stainless steel filter heads with dual ports like I did to eliminate corrosion issues on the Racor. It will accept the Racor S3213 Merc style filters.

If those tanks are foamed in, they definitely aren't original, as Carl Moesly never put foam up against an aluminum fuel tank! A friend of mine bought a 27 Seamaster new in 1967 with an I/O. He upgraded from a 350 to a 400 and finally a 454 cu. in. engine before he got acceptable engine life, but he was very happy with it after that. He had a custom fuel tank made for it that I believe held about 150 gallons, and he used to run all over the Bahamas with it. With bracketed outboards, you should have room under the aft deck for some big fuel tanks if needed!
