Coffcraft uses 4 cycle engines. The thrust engine is a Geo Metro G-10, 3 cylinder low mileage JDM engine (imported from Japan) with an average 40,000 to 60,000 miles. Although the engine is used, I guarantee it to be trouble free for a period of 1 year.

The lift engine is a brand new 12 hp Briggs and Stratton. Even running (2) 4 cycle engines, one being an automotive engine, fuel economy is still much better than a single 2 cycle engine. Averaging 1.5 to 2 gallons per hour as apposed to an average 3 to 6 gallons per hour with a 2 cycle engine.

Using automotive and low tone mufflers, Coffcraft machines are much more quiet than any other manufactured 2 cycle hovercraft. The large diameter slower spinning 2 blade propeller is also much quieter than a multi bladed faster spinning fan.

Lets talk about craft. Not all, but most other manufactured hovercraft are of single engine design. That's to say, the the craft gets both lift and thrust from one engine. When you want to slow down, letting off the thrust also decreases lift cushion pressure. This decrease in cushion pressure can and often does result in what is known as plow in. Plow in is when the skirt tucks under the craft dropping it to the surface and is known quite often to be very violent, often tossing driver and/or passengers out. This is extremely important when turning or sliding sideways where the craft can dig in and flip over.

While no craft is exempt from plow in, it is much less likely in a twin engine craft. One can let off the thrust while the cushion pressure stays the same or can be increased. Proper plow plane design of the under hull also reduces the severity of the plow, letting the craft slow rapidly rather than digging in and a sudden stop. I have personally plowed the Venom GT-S prototype forward twice. Once at 52 mph with 2 aboard, and another time at 45 mph with 3 aboard. The plow is very gentle with no tendency to eject occupants.

Investing in a hovercraft is a big decision. But so is any other recreational vehicle. Before you decide. Do your home work. There are many different types of hovercraft. Single engine single fan, single engine twin fan, twin engine, bag skirts, segmented (finger) skirts and the list goes on. All have advantages and disadvantages. Weigh the options before deciding.

 With Coffcraft, safety, reliability, power and torque of 4 cycle engines, availability of off the shelf cheaper repair parts, controllability of separate lift and thrust systems, quietness, ease of maintenance,  and cost to own and operate, the choice is simple.
