These are very portable with features such as built-in integral fuel tanks, and convenient carrying handles. They are lightweight and compact in design and can be easily transported. This hp range is ideal for a variety of application including small inflatable boats up to 3. Engines in this hp range are typically 1-cylinder, although some 2-cylinders do exist. A heavy person or more than one person in a hull in this hp class can have a dramatic effect on hull performance making plaining difficult.
Engines in this hp range feature heavier duty construction and enhanced manoeuvrability features such as forward-neutral-reverse gears. These engines may have integral fuel tanks or separate fuel tanks. You also need to know a well maintained four-stroke gasoline engine is estimated to burn about 0. For example, if you want to determine the fuel consumption for a horsepower gasoline engine, you would calculate 0.
As with most decisions related to boating, the use of the boat is always a factor. Are you using the boat just to cruise with friends and family? Or will you be pulling water skiers, wakeboarders and tubers? The addition of pulling someone behind the boat — and the additional weight of storing watersport accessories — increase the need for power and are often a reason to consider adding horsepower to your boat.
The rule of thumb is based on weight alone, and says you should have between 40 and 25 pounds of weight for each horsepower. For example, a 5,pound boat could have an engine with between and horsepower. While this rule of thumb can be a helpful way to get a ballpark range, it still requires some guesswork when it comes to considering your boat handling.
Is it illegal to overpower a boat? According to the federal government, yes. There are a few different ways you can define overpowering a boat. The horsepower capacity section of the Code of Federal Regulations contains its definition of overpowering a boat.
There are two different ways the federal government uses to determine the maximum horsepower for any given boat — one is a computation, and the other is a performance test. The way that is used depends on the boat. For the majority, the computation method is best to use. You multiply your boat length by the transom width. Note: For flat-bottom hard-chine boats, with factor of 52 or less, reduce one capacity limit e. The performance test method is for boats that are 13 feet or less in length, have remote wheel steering, have a maximum capacity of no more than two persons and at least a inch transom height — or at least a inch motorwell height and at least a inch transom height.
Through this method, there are very specific instructions for boat preparation addressing everything from motor mounting to fuel tanks to ensure consistency. There are equally as specific instructions for the conditions in which you can perform this test.
The first part of the performance test is the quick-turn test. Setting the throttle at a low maneuvering speed and facing straight ahead, you then turn the wheel degrees in half a second or less and hold it there. If you can complete the degree turn without losing control of the boat or reducing the throttle, your boat has passed the test. Repeat, increasing the turn in speed until you can no longer pass the test, or you reach the maximum throttle. Boat shows are back for the Fall and Winter season!
Intent on improving the overall boat show experience for new and experienced boaters alike, the upcoming show season promises to be bigger and better than ever—for the entire family. Skip to content.

Additionally jet drives can often be noisy and less fuel efficient compared to other options however, newer versions have improved in these areas.
If speed on the water is what you seek, surface drives will do the trick. This propulsion type is an inboard engine with a propulsion unit that extends out the back of the boat as opposed to the bottom.
The propeller is partially out of the water while running which reduces cavitation and provides high levels of fuel efficiency and performance. Surface drives can often come with higher maintenance costs due to the large number of moving parts. An early developer of the drive was Howard Arneson. Arneson developed surface drives primarily for catamarans and V-boats. Pershing Yachts make full use of the Arneson drive. Pershing yachts can often be identified by the rooster tail kicked up by its surface drives.
Pod drive propulsion systems have been around since , and an increasing number of cruising yachts have been outfitted with pod drive systems. Instead of a traditional shaft-based propulsion system, pod drive systems have one or more self contained pods mounted to the bottom of the boat that transfer engine power to thrust. Pod drives tend to offer increased fuel economy, handling and performance.
Additionally, position fixing and joystick docking are a breeze. Pod drive systems tend to cost more and finding the appropriate technicians to maintain and repair such systems might be slightly more difficult than traditional propulsion systems depending on your location. Choosing between an outboard and a sterndrive engine is a common question for recreational boats, perhaps most commonly with bowriders.
While in the past, most bowriders came standard with a sterndrive engine, boat manufacturers today are giving most bowriders the option for outboard power.
Outboards enable a more fishable transom and while you lose space on the back, you typically gain a more spacious cockpit for storage or seating.
Aesthetically, many boaters like the clean lines of a sterndrive design with a sun pad and swim platform. However, based on personal preference, some enjoy the look of the outboard motors. Performance - The power-to-weight ratio is an important component when analyzing the performance of outboard engines vs.
With recent advances in outboard engine performance, horsepower can often be similar when comparing outboard engines with sterndrive engines. Outboard engines win by a significant margin on the weight factor. Hence, the power-to-weight ratio of an outboard powered boat is going to be better than a sterndrive boat.
Fuel Efficiency - Because outboards typically mean a lighter boat, this translates nicely into fuel efficiency - even while outboards tend to run at higher RPMs. If the amount of fuel you burn while boating is important to you, then an outboard engine might be the best bet. Maintenance is definitely easier with an outboard as the self-contained unit is quite accessible.
