Cant wait for the 60 E-TEC so I think I am going to get a Merc 60. Boat used mostly for fishing not to concerned with speed but want best motor for wake/knee boarding the kids. Bigfoot or Small foot? boat is a BW 15 cc

The Bigfoot motor is more of a "utility" configuration. Your hull weighs about 550-575 lbs. The standard lower unit is what you want. The 50 curbureted version I had on my 15cc pushed it at just under 40 mph gps. That 60 EFI (non-bigfoot) will pull the kids (or adults) up to speeds that'll scare 'em half to death...

I have a 1978 15ft striper with a 2004 merc 60hp EFI small foot. See my earlier post about performance with 60hp EFI 4stroke. The small foot weighs less than the bigfoot which is why I chose it. I do mostly fishing, some skiing. We get 36mph with 10inch dia, 17pitch aluminum prop and three in the boat. The striper is a little heavier with side console, pedestal seats, side rails. You might be able to turn a slightly larger diameter prop using the bigfoot. I'm sure I could get @40mph with raising the engine 1 hole and changing to SS prop. I cruise @ 25 and that is fine with me. The added weight is noticable especially in hole-shot. I used to run a 1991 4cylinder 2smoke 40hp that would run 32-33 with SS prop (it really was more like a 50hp). It weighed @183lbs. The boat is much less sensitive to weight loads with this new motor-it feels like it has more torque. I am moving my 12 gallon gas tank a little forward and that should help.
