With 1 person in it say 180 lbs. It will go 15-20 mph. This assumes the outboard is running well and the prop in good shape.
Speed is dependant on a number of factors. Most importantly the size, type and weight of the boat that it is on and the number of people on board. A 50 HP outboard will push a small aluminum fishing boat a lot fast than it will a 20 ft fiberglass boat. I have a 50 HP 2 stroke that will push a 16 foot aluminum boat 35 MPH.
width of 12 foot aluminum boat
The answer is relative. I have a 4 1/2 HP motor on my 12 foot aluminum boat. It gets me where I need to go.
not sure how wide your Jon boat is but I would go with a 3.5HP or 5HP outboard no bigger
159lb
There are too many variables here to give you a solid answer, but my 21 foot Santana Sail Boat (weight approx: 1600lbs) goes 8-10mph.
The right size for an electric outboard motor for a 10 foot fishing boat seems to be 4 - 5 - 6 hp, 8 - 9.9 hp or 15 - 20hp. It simply depends on what kind of fishing boat it is.
A ski boat. Any type can "plane out" going fast enough though a v-hull would be the most common fro fast boats. It is a factor of the size, length, and weight of the boat and the power of the motor. A 15 foot aluminum boat can plane out with a 15hp outboard.
Depends if you put it on an 8 foot skiff or a 40 foot barge.
around 95-97mph, if its a day when alot of water is out,,, if a foul, less watery day, then only around 90mph
I have a 40hp Suzuki 2 stroke (almost new) on a 4.5 metre/14.5 foot aluminum runabout and depending on the conditions it does between 24-30 knots
Fast as heck. Most 14 fosters have a 10 to 15 horse and go around 15mph. A 35 horse would probly get it going over 30 mph.
