Good morning, I'm far from an expert on this, but I too own a 46', 1984 Uniflite. As far as I can tell....and this is an estimate. 1900 rpm is a good speed which gives you about 1 gallon per engine per mile. Probably not exact, but easy numbers to work with. The information on my boat indicates two, 50 gal tanks in engine space and 400 gallons under the bed in the captains quarters. As far as I can tell there are cross feed valves between tanks. Mine appear to be open. Like I said I'm no expert so if someone has better information........ Good luck frank

I'm trying to get a feel for what I might expect with respect to fuel efficiency. Hence, if anyone with comparable engines could respond with the following info, I'd be very grateful: 1. Your engine's "sweet spot" in terms of engine RPM and related speed. IOW, at what RPM/speed do you get the best fuel efficiency? 2. What is your average fuel consumption in gph at this ideal RPM/speed? 3. If not the same as #1, what RPM/speed do you generally cruise? 4. What is your fuel efficiency at that RPM/speed? For each engine, I'm told this vessel has a 68 gal. tank forward and a 182 gal tank aft. Do I need to switch between these tanks or is that done automatically? How? Thanks for any and all responses.
