2001 Mercury 25 Big Foot 4-stroke

[rbruce63]

I would like your opinion on a Mercury 25 Big Foot 4-stroke that is new at the dealer's. What does big foot mean? Can I get better speed with this 186 lbs heavy motor in my Boston Whaler Sport 11' rated at 570 lbs max vs. my current rigging with a 72 lbs heavy Chrysler 20 HP?

Not really an engine trouble question, RBruce.<br /><br />Your BW 11 is rated for max 20hp. The 11 does not respond safely to overpower or overweight engines.<br /><br />The "Bigfoot" engines have an oversize gearcase/foot and larger props for operating displacement hulls, like pontoons and barges.<br /><br />Moving to general outboard.

JB:<br /><br />Thanks. All the 25 HP's are beyond 110 lbs of weight. My current Chrysler 20 HP is at 72 lbs. All the current two strokes at 15 HP are within this weight, however, displacement of these current motors is below my Chrysler's. This big-foot motor is quite heavy at over 180 lbs and it is discarded. Wouldn't I be paying a lot for a motor that performs about the same?
