1978 MA rebuild.

Leland, I think the 115 Zuke will net you at least 4 miles to the gallon at 4,000 and probably 18 knots so theoretically you should have a 100 miles range with the 25 gallon tank. If you launch at either beautiful Cockraoch Bay or lovely Bullfrog Creek, you are probably limited to 60' of water off of Egmont. However, then you are faced with running headlong into one of those Avon Park manufactured afternoon thunderstorms in Tampa Bay "trying to get back to the trailer". If you drag it over the Skyway to Ft. DeSoto you are probably good to 90' west of Egmont and maybe get to the pipeline for some A.R.'s for our generous there day season. I have a 32 gallon tank on my 19' Sawzalled bowrider with a 90 E-etc triple and usually burn about 20 gallons a day running to 40' of water off of Bayport which is about a 75 miles day, with maneuvering on spots, when I'm out there. So in summery, if you put the 40 gallon tank in you'll be set for all conditions and situations.
P.S. you are in charge of the Strawberry shortcakes at the next West Coast Gathering and Don likes his with extra whipped cream.
