    The Outboard Expert: Fuel Economy Secrets. Hot tips for stretching your fuel dollar. By Charles Plueddeman It's bad for efficiency and hard on the prop-shaft bearings. Get your prop fixed or buy a new one. When your speed over the water starts to go down, you've passed the most-efficient trim setting, and some boats take a lot less trim. 2. Electric Motors Bureau of Energy Efficiency 26 Motor Characteristics Motor Speed The speed of a motor is the number of revolutions in a given time frame, typically revolutions per minute (RPM). The speed of an AC motor depends on the frequency of the input power and the number of poles for which the motor is Size: KB.

      The Honda motor in these pictures appears to be a short shaft? It was hard to get to the rear of the boat as I am in Michigan, it is in deep snow & pushed against a shed. I have looked on different websites and it seems the rule of thumb is inch transom = short shaft while inch tranasom = long shaft.   4. Shaft Support When you haul the boat, make sure the propeller shaft angle is 10 degrees or less (below the horizontal plane) for maximum efficiency. Also, the strut should be foil-shaped in cross sections to reduce drag, with the top of the strut recessed into the hull to .

The PATENTED EASY V1 Long tail shaft separates into two pieces making transport easier and makes shipping to you less expensive at the same time. The kit is designed for hp to 5hp motors by using a 5/8. The EASY V1 kit is designed for sneak boats, canoes, layout boats, jon boats etc.5/5(1). So a 10Hp outboard is actually a little more after the gearing while a 10 Hp long shaft-long tail will have less Hp at the prop side after losses in the bearing.

The outboard thrust line is almost parrallel to the waterline increasing efficiency while a long tail is forced to have an angled thrustline which could affect planing or trim angle. Black Pearl is the world's most advanced superyacht, offering true zero-emissions cruising, which is unheard of on a boat of her scope and size.

The yacht's controllable pitch propellers feed power back into the ship via a pair of shaft generators, providing enough power to support the yacht's hotel load. As mentioned already, they are called 'long tail' boats.

they are a common sight in Thailand on the rivers and canals there. They are extremely efficient and fast and relatively stable but I don't think I'd want to be out at sea in one. Some more sea kindly, larger beamed boats also use the same engine and shaft arrangement.

A long tail boat motor for any shallow water. When you need to get to the hard to reach places, the Scavenger is the ultimate boat motor for any shallow water.

If you need a boat motor for those shallow, muddy, rocky places a Scavenger boat motor is for you. The Scavenger has it all with the durable design. But the ocean is a lumpy place. Swells boom across oceans at speeds of over 15 knots.

And when a swell or a wind ‘chop’ slam into a hull heading in the opposite direction, the wave energy can impede a boat’s progress with a slam. But if the slam can be reduced, by sharpening the hull into a pencil thin shape.

KKK GROUP COMPANY is a manufacturer of long shaft propeller, we provide an alternative water transportation long tail boat. We guaranteed that our quality is the best long shaft propeller. This setup is 50% more efficient than a standard outboard motor and capable of going where no outboard can go.

I did this for a couple thousand dollars. With some ingenuity you can add solar and wind capability, cutting back in your environmental impact, further cheapening the cost of going there, and adding a great sense of adventure. The most powerful electric sail drive from serial production is a Torqeedo.

The Deep Blue 40 SD propels sail yachts of up to 40 feet in length to speeds of up to almost ten knots (18 km/h), or smaller boats even faster when planing. This makes cruising with large sail yachts completely emission-free with virtually no noise or vibration.

A long-tail boat is a boat which has an engine mounted on it’s stern, the engine and propeller shaft are able to swivel through more than degrees, the defining feature of the Thai Long-tail boat is the length of it’s propeller shaft, the propeller.

The Inboard motors use direct drive or V-drive transmissions to power engines. They are popular for the large power boats over 30 feet.

This type of drive shaft sits completely submerged in the water and are normally used in larger power boats. Performance: The weight of the I/O are centered deep in the hull of a boat. This improves the. Long-tail shaft drive for energy efficient boats: final report / prepared for Small-Scale Appropriate Energy Technology Grants Program-Regin IX ; prepared by Herman : Herman.

Hastrup. Long shaft – - inch length. Propeller – bigger Aluminum propeller of 15 to 16” dia. Load capacity – kgs. Applications – transportation, tourism, sand mining, large fishing boats.

Weight – Total 72kgs along with engine and long tail assembly. Except for high-speed boats, the larger the propeller diameter and the slower the shaft rpm, the more efficient the propulsion. Remember, for large diameter you need low shaft rpms. Indeed, one of the most frustrating things I run up against as a designer is finding deep reduction gears to mate with smaller engines — engines less than or.
