How much weight can a 25 hp outboard push?
25 hp – 155 lbs.
How fast do outboard motors go?
Most high-performance center-consoles are powered by two to four outboards. Top speeds range from 60 to 85 MPH. Today’s most popular go-fast catamarans range from 28 to 52 feet. Powered by twin inboard engines up to 1,750-HP, they can reach 180 MPH and beyond.

How much horsepower do you need for an outboard engine?
This Article is primarily based on motors under 40hp. Matching the correct outboard horsepower for your boat is probably the single most important factor when buying an outboard engine. There is a fine line between overpowering and under powering your watercraft. When you overpower the boat you often risk damage to the boat and compromise safety.
How to determine outboard motor propellor size and pitch?
Pitch is always a whole number; if you get a fractional answer, round the number off. For example, if the diameter of the propeller is 14 inches, the radius of the propeller is 7 inches. The angle of the blade is 20 degrees. The tangent of 20 is 0.36397. 0.36397 x 6.2831 x 7 = 16.0080.
What kind of motor does a small outboard have?
Small outboards are common for portable boats such as canoes, folding boats, inflatable boats, dinghy’s, small sailboats, small pontoon boats and other small light weight boats. These outboards are often two strokes but four stroke engines do start from 1.5 and up. They usually do not have gears although some might have ‘Drive’ and ‘Neutral’.
How to calculate outboard motor size for sailboats?
To get the right amount of horsepower needed to efficiently propel a sailboat, divide the displacement of the boat (in lb) by 550. You need approximately 1 HP per 550 lb of displacement or 4 HP per 2200 lb. Most sailboats don’t need a motor with more than 30 HP.
What should the propeller RPM be on an outboard?
The propeller choice directly affects the engine RPM and therefore its performance. Choose a propeller that puts the engine RPM at the midpoint or higher of the wide open throttle (WOT) range with a normal load. This operating range will translate to the highest horsepower available from your outboard.
What kind of boat should I get with 25 hp?
Many of the boats appear that a 40HP would be more appropriate, but i would like to keep it at 25HP without being a “dog”. You should look at a modified V Jon boat. The flat bottom will be super stable to fish out of. The 25hp will get the boat on plane no problem.
