This may have been covered before, but I did not see it.

Why would you get a big foot outboard for the 150 Sport ?
I noticed many have gotten this option.
I understand it has bigger gears and a larger lower unit, but is not this overkill for the Whaler hull ?
I know it will be money $.

Is not this outboard for pontoon boats mainly ?

Would not a regular Merc 4 stroke EFI provide better performance ?

I have the standard 50 4-stroke on my 15CC (a lighter boat than the 150) and it's superb. I may be mistaken, but I believe the Bigfoot has a lower gearing to gain low-end torque. IMO, for general all-around boating/fishing/cruising, I'd stick with the standard unit.

Bigfoot is intended for workboat/pontoons etc. and most hulls will perform better with the standard lower unit. Less drag from smaller lower unit and more prop selections! Happy Whalin'... Clark... Spruce Creek Navy

Dave, it's this simple. Whaler only offers the BigFoot version of four-strokes on the smaller Whalers. That's why so many of have them.

There are two exceptions. The first is the 40HP on the 130. The 40HP small foot is a lighter, smaller displacement 3 cylinder engine within the weight limits of the 130, while the bigfoot version is the same 4 cylinder engine as the 50 and 60 HP motors, too heavy for the 130. The second is the less-than-max 15HP on the 110 Sport, and while there IS a 15HP 4S BigFoot, I suspect they're trying to offer a "portable" motor (110 lbs).

I have to believe the engineers at Whaler know what they're doing and that there's a good reason for this.

Just out of curiousity, I checked the prices at:

http://www.edsmarinesuperstore.com/mercury.htm

60 HP REMOTE LONG TNT EFI 4-STROKE MERCURY $5,499

60 HP REMOTE LONG TNT EFI BIGFOOT 4-STROKE MERCURY $5,299

The BigFoot is $200 less on the 60HP. On the 50HP, it's $300 more.

50 HP REMOTE LONG TNT EFI 4-STROKE MERCURY $4,999

50 HP REMOTE LONG TNT EFI BIGFOOT 4-STROKE MERCURY $5,299

Strange...

My impression of the pricing provided by a retailer like "Ed's" is that it reflects current inventory and market demand. It could be that "Ed's" has too much inventory of a certain motor, or other considerations that would affect the price at which he was currently willing to sell. A comparison of the actual MSRP might be more appropriate.

OK I think I know the answer. A big foot has a different gear ratio (lower) so it can turn a steeper pitch prop. Like putting "mudder" tires on a truck you get better bite but you need a different (lower) gear ration to turn those big tires otherwise you bog your engine. I have a Dauntless 14 with a 75 merc 2.33:1 gear ratio, basically a bigfoot(the only way it comes). I use a 19"pitch SS prop or a 21"pitch alum. That's pretty steep. Hope this helps.

That's a good point. The "smallfoot" 60HP is 1.87:1 vs 2.33:1 for the BigFoot, where the common prop pitches are 13-15" (Whaler uses the latter) at 60HP. The smallfoot would have to be running a 10-12" prop to give the same thrust, and maybe even more on account of the smaller diameter prop.

With the newer Whalers being heavier boats than the old ones you need the "Mudder" tires (uh, steeper pitch props) to get them moving. Better bite less cavitation. Does that all make sense?

It really seems to work with my 14 Dauntless. 1000 lb., 2 batteries and 25 gallons of fuel plus my 208 lbs. and a wife and son, cooler of soda, water and chips, skis, rope, anchor, a couple fishing rods, too many lures, live well full of water cuz I forgot to close the spigot thing and it filled up with the forward motion of the boat, now our 3 beach towels weigh 30 lb. PLUS i forgot to put the ladder back up.

It makes a lot of sense and seems to work very well with our 900 lb 150 Sport, 280 or so lb motor, and 800 lbs of people, gas, 2 coolers, and quite a bit of gear.
