The speed of a 115 hp outboard motor can vary based on several factors, including the weight of the boat, its design, and water conditions. Generally, a boat powered by a 115 hp outboard can achieve speeds ranging from 30 to 45 miles per hour. Lighter, more aerodynamic boats may reach the upper end of this range, while heavier boats will likely be slower.
What mph compare to a 3.3 horse power outboard motor
8-15
I have a 1980,115 Johnson Outboard on a Very Heavy 16ft Crestliner Fiberglass boat,I can get it up to 62kms per hour with 4 people in it .(I used a GPS to test this )
It depends on the size craft it is pushing. A 5hp outboard should run fast enough to plane out say a 10 to 12ft. aluminum boat with one man aboard.
You will notice on the throttle handle that there are three positions on the legend. "Really Slow", "Start" and "Slow".
A 3.5hp outboard will give you 8mph tops, which would be a normal walk to a slow jog.
I have a 14/36 flat boat with a 15 and it goes 26mph with only me and minimal gear.
on my avon air floor inflatable in okinawa with 2 and fishing gear about 4 to 6 mph. avon 310
it has a shaft that go in the motor that moves the boat =-Þ
carburator jets clogged!
It really depends on how big your boat is and how fast you want to go typically you want to go 20-25 while tubing so get a big enough motor to push your boat with a tube 20-25 mph
the 20hp Mercury outboard motor runs at the most at 8mph on a good 14ft to 16ft aluminum boat. Mercury.co
