Maybe 10 or 12 knots.What speed should a 18' pontoon boat with a 40 horse murcury bigfoot motor go?
speed is often the hardest question to answer, as there are so many variables.



rough water, wind, weight on board and balance of weight, condition of boat and motor, condition of prop.....

and that aint all.



pontoons boats arent generally the fastest out there (or most agile).

despite mostly alum construction, they are still among the WIDEST and squarest boats out there, which makes them heavy for their length.



and 40 isnt that much power for one either (just a guess, but you are probably rated for at least 60 hp max).



the best you can get are rough guesses, but having seen more then one pontoon in that size and power range, 20 mph give or take a couple.

if you got a portable GPS unit, they usually say speed and are usually more accurate then the built in speedos.
