From the factory, [the 2004 150 SPORT model of Boston Whaler boat comes] with a 50 HP and only one 6 gallon gas tank. She has very little range. What improvements are tested, feasable and available?

I'm sure jimh will be along any moment to correct the thread title to 2004 150 Sport Fuel Range or something like that (to distinguish it from the classic 15 Sport model)

The only two engines available on this boat have been the 60hp Classic carbureted 2-stroke, and the 60 hp BigFoot EFI 4-stroke. Forum members with the 150 Sport EFI four-stroke include lakesidelou, Budman, sportroyalwulf, kshoaps, and me (Moe). Those with the two-stroke include bob wallace, Techmage, and tombro.

Most of us have at least added a second tank. My dealer put it sideways on the other side of the seat support, a mirror of the factory tank, where it's not in the step-through. For weight distribution, I'm going to move both tanks to the port side longways, even though that puts the corner of the inboard tank in the step through. My 4'10" wife has no problem stepping over it, and it puts the fuel gauge of that tank as the primary right where I can glance down at it. If I really needed it, I could put up to two more under the starboard side of the helm seat.

In this thread, , bob wallace revealed that he found the range of his two-stroke to be 56 miles on two tanks. However, since he's often in so shallow of water that he can't stop to swap tanks and get back on plane, he provided details of a 14.5 gallon Tempo tank he planned (at that time) to mount under the port side of the seat. Along with that, a factory tank under the helm seat would provide that 1/3 backup, but it would also be possible to mount a second Tempo on that side. Bob's since completed the Tempo installation and it turned out nice. I believe Tombro is also going to go with the Tempo tank, since he goes out into the Atlantic fishing.

I don't have a GPS, but know from mileage on the charts that we routinely get 35 miles or better on a tank with the EFI 4-stroke. It's 14 miles one way to the north side of Upper Bass Island from where we launch on Lake Erie, and that's just the start of a day for us. Going out to Middle and West Sister Islands will be 21-24 miles out, and with time trolling, and coming back, I'll definitely add a 3rd tank for backup. I like being able to move the tanks from the boat to the truck to take them up to the gas station, so I'll stick with the portables.

Hope this answers your question. In this link, I've listed a number of other links to 150 Sport threads:

You're welcome, Swellmonster!

Jim, I'm a bit surprised that you didn't change the 15' Sport in the title to 150 Sport, as you have in other threads. That would help those who use their browswer's "find" function to look for posts about the 150 Sport.
