60hp Merc Bigfoot ELPTCT on LUND 1625?

[duke2555]

I have a chance to get a 2022 60hp Merc Bigfoot ELPTCT with 1 year warranty left on it at a good price and upgrade from my 40hp Merc ELPT, I know the Bigfoot is meant for heavy crafts like pontoon boats with a higher gear ratio and a larger lower unit and typically a bigger prop.

I can get approx. 25-28mph at 5500rpm with my 40hp, is the Bigfoot the right choice to upgrade to a 60hp? What kind of speed can I realistically expect? I would like to see at least a 10mph increase.

Comments appreciated.

Thanks

First question, what is the boat rated for.  No point in putting a saturn 5 rocket on a Sopwith Camel.

My Lund is rated for a 60hp motor.

If it has lower rpm but bigger torque, you just put on a larger pitch prop problem solved

I have a Lund 1625 Fury XL with a standard Merc 60 4-stroke (not Bigfoot). By myself, on a flat lake, I've touched 36 mph at 5500 rpm. I'm not sure how the added drag of the larger and deeper lower unit on the Bigfoot will affect that number. Bigfoots are designed to provide greater torque at lower speeds with a larger diameter prop. With the higher gear ratio it may be difficult to find a prop that will give you top end speed without over-revving the motor.

Holy $#@#....i laughed because I have no idea why I know what a Sopwith Camel is.

my assumption is that these 60 horse bigfoot motors are for barging?
