Off the top of my head there are 3 ways of propelling a boat either through the use of a conventional propeller an impeller or jet drive and aircraft style propellers typically found on flat bottomed air boats used in marshlands where below waterline propulsion is impractical. For most of us the choice will come down to propellers or jet. There is a point in having the inlet as far aft as possible since any bottom surface aft of the inlet will generate a new boundary layer with the corresponding additional losses.
Beyond that the outboard versus inboard mounting is more a question of mechanichal design of. If you maintain your jet boat you can keep the cost of maintenance down but the routine tune-up costs will add up over time. Reverse and Changing Speeds.
Jet engine boats can run at both high and low speeds but when they run at a low speed for a. Go to lake and get a Quagga muscle inspectionerr put boat in water and start engine once warmed up switch to the other tank cause your out of gas on that tank hammer the gas to the floor run engine at 5200 RPM for ten minutes get ticket for being too damn loud turn around and go back to dock and add two of the 5 gal. Gas cans to each tank but do so with boat on trailer because filling boats in.
A jet boat draws water under the boat and expels it through the stern. To ensure the efficient performance of your boat with minimal hull resistance from the struts rudders and shafts an appropriate drive is necessary. Boat jet drives are available in brands such as American Mercury Jet OMC Sierra and Yamaha.
Click to expand. A Jet Drive uses an impeller in a tube which sucks in water from the bottom and shoots it out a nozzel at the stern at a high rate of speed. As water is expelled backward the boat moves forward think of how a rocket works Here is a fuller explanation from the Hamilton Jet Site.
I always recommend people with jet boats start with AT LEAST 1200lbs of ballast keep in mind the bigger the boat the more ballast you need to sink the hull and I recommend you place it as far back as possible. Jet boats may have one or two engines and jet pumps. The boat is steered by a movable nozzle that aims the stream of water left or right.
A diverter called the reverse bucket drops over the jet nozzle to create reverse thrust. Because the entire jet drive system is located within the hull a jet boat has minimal draft and can operate in very shallow watertheres no propeller or outdrive that could be damaged by. Dual jet propulsion drives draws water in through the intake cavity usually located in the base near the rear of the boat that splits into two separate dedicated channels and feeds two separate jet units.
Mesh grates are used in the main water intake cavity to stop large objects from being sucked up. The water is then forced out of a nozzle. Jet boats are not fuel economical.
The boat motors run a higher RPMs compared to stern drive boats. Takes time to get used to different speeds. Jet boats run at both high speeds and at low speeds and it may take some time for experienced boaters to get used to the feel of different speeds.

Only a few manufacturers focus on recreational jet boats but recent years have produced a spike in new technology and systems to reduce the performance gap with sterndrive- and outboard-powered runabouts. Anatomy Of A Water Jet. Compared to outboards inboards and sterndrives a direct drive jet-propulsion system is remarkably simple.
Operating Your PWC Jet Ski WaveRunner or Sea-Doo. A PWC is propelled and steered by a jet of water that exits though a nozzle at the back of the craft. When you steer the handlebar you are moving the nozzle left or right.
