What is a good horsepower for a boat?
For every forty pounds of boat weight, you need one horsepower to motor along over smooth waters at 20 miles per hour. So for a 4,000-pound boat, that’s 100 horsepower for smooth, steady cruising. For an 8,000 pound boat, that’s 200 horsepower.
How fast can a boat with 150 hp go?
A single 115 to 150-hp engine can produce a reasonable performance for an entry-level fiberglass sportboat from 17′-19′, depending on the load. With it, a powerboat in this range can have a top speed from 40 to 45 mph, with cruising speeds in the mid-20s.
How is boat horsepower measured?
Shaft horsepower is measured at the prop shaft. It’s bhp minus the power lost to gears and bearings. Since outboards and stern drives have built-in gears and bearings through which they power the prop, these engines are rated for shaft horsepower.
Is there such thing as too much outboard horsepower on a..?
Of course, this is not your everyday fishing boat (it was a drug smuggling boat), but needless to say, this boat probably is wee bit heavy in the outboard motor area… But in all seriousness, are we reaching a point of outboard motor horsepower mania on the new boats today, or is all of this power and new boat motor technology a blessing?
Why do boats have a maximum horsepower rating?
It seems obvious that the maximum horsepower rating is to keep us from speeding out of control with an oversized engine and, since these ratings are mandated by the U.S. Coast Guard, it’s a logical assumption that these capacities are the result of their testing. Wrong on all counts.
