3 Tips to help improve your outboard jetâs performance Luckily, there are some things you can do to help make your outboard jet run like new again. Intake Grates. With an outboard jet, most of your bottom strikes are going to occur right on the grates on the underside of the shoe. Once good “thunk” on the bottom can bend several of your grates. And it’s pretty simple – the more bent up those things are, the more the motor has to suck to get water up inside.

Outboard and Inboard Engines; Stern and Jet Drives Outboard and Inboard Engines; Stern and Jet Drives. 1  An outboard is a portable, self-contained package of an engine, gear case, and propeller that is attached to the transom of a boat. An inboard is a four-stroke automotive engine adapted for marine use. 2  Inboard engines are mounted inside the hull's midsection or in front of the transom. 3  The engine turns a drive shaft that runs through the bottom of the hull and is attached to a propeller at the other end.

7 Ways to Increase Your Vehicleâs Horsepower and Torque A larger throttle body delivering air at a higher rate helps you feel faster acceleration and a surge in engine power by up to 25 hp. Additionally, you can install a throttle body spacer to further enhance your fuel economy and increase engine torque.

Outboard and Inboard Engines; Stern and Jet Drives Jet Drives. 1  Jet drives propel a vessel by forcing a jet of water out the back of the vessel. 2  Personal watercraft are the most common type of vessels that use a jet drive.  Jet drives also may power larger vessels (jet boats) and are used commonly for vessels designed for shallow water conditions.

What pitch of prop should i use for speed on a 18ft boat? In general to increase top speed you would step up your prop. For example if you are using a 19 pitch prop now then you would increase the number IE: 21. This will decrease your ability to plane out as easily and the low end power will be diminished IE: pulling water skiers out of the water, etc.A stainless steel prop will help with overcoming the plane out/low end issues.n general to increase top speed you would step up your prop.

About Carbon Monoxide Alarms Carbon monoxide detector chirping? Is your carbon monoxide detector (alarm) trying to tell you something? Carbon monoxide (CO) alarms monitor your home 24 hours a day, 7 days a week, and are designed to provide accurate readings for the life of the alarm. But they don’t last forever. When your alarm nears its end of life, it will let you know by beeping 2 times every 30 seconds.

- Impressive power and efficiency make turbofans the engines of choice on everything from passenger jets (typically using high-bypass) to jet fighters (low-bypass). The bypass design also cools a jet engine and makes it quieter.

- Always adjust the idle setting with the engine fully warm. Screw in the idle-speed screw (4) to obtain a slightly-higher idling speed than normal (about 1200 rpm for a four-stroke engine or about 1400 rpm for a two-stroke); Then adjust the air-adjusting screw (1) to obtain the most even running.

Carb Quick Guide Always readjust the idle mixture (#2) and idle speed (#1) screws after making a jet change. To test the main jet, do a roll-on from 50-mph to 70-mph in 3rd gear. If the engine backfires or breaks up in the carb, increase the main jet size .004.

How to Make a Jet Ski Go Faster Remove any excess weight from the jet ski. Look in any storage compartments which may contain large, heavy or unnecessary items and remove them. The less the jet ski weighs, the faster it will go. Sit on the jet ski and place the key in the ignition while you start it up. Next, place both hands firmly on the handlebars and squeeze the gas. This will make the jet ski go faster.

Moving Up to a Jet I think that most pilots new to jets are surprised, at least a little, by the time it takes the engines to spool up or down, and by the amount of power available. The certification rules allow a jet engine to take as long as five seconds to accelerate from idle to maximum power.

- Airliner jet engines such as a Boeing 737 burns about 3,500 pounds of fuel per hour at cruising altitude and speed. Thats a little over 500 gallons per hour per engine.hen the air is colder (it easily gets -40  degrees up there) and the fuel air mixture is burned, the air  expands alot more than if warm air was entering the engine. On a  warm day a jet will not perform nearly as well as on a cold  day.

What is top fuel and how is it different from gasoline? What is top fuel and how is it different from gasoline? If you want to make a high-power 4-stroke engine, there are a couple of different ways to accomplish your goal. One way is to increase the displacement. Another is to stuff more air into the engine with a turbocharger or a supercharger. If you want to go to extremes, you would replace gasoline altogether and use a more energetic fuel. Top fuel dragsters do all three.

Outrunner This makes an outrunner an excellent choice for directly driving electric aircraft propellers since they eliminate the extra weight, complexity, inefficiency and noise of a gearbox. Outrunner motors have quickly become popular and are now available in many sizes.

How to Decide Between a Two- or Four-Stroke Outboard Boat Engine The air-fuel mixture flows into the combustion chamber through intake valves, and the exhaust leaves the engine via exhaust valves. Because of these intake and exhaust valves (the valve train), a four-stroke outboard is usually heavier than a two-stroke outboard of the same horsepower.

- (It uses a small part of the top photo on this page, taken by Ian Schoeneberg courtesy of US Navy.): 1  For a jet going slower than the speed of sound, the engine is moving through the air at about 1000 km/h (600 mph). 2  A fan at the front sucks the cold air into the engine and forces it through the inlet.

How to Swim Faster Freestyle . . . By Decreasing Drag The quickest way to increase your swimming stroke speed and freestyle technique is by learning how to decrease drag and inefficiency and not by increasing power. The drills and instructions shown can be used whether you are coaching, preparing for triathlon swimming, improving your swim stroke or just learning to swim.

Jets Vs. Props The twin-engine jet boats are also 10 dBA noisier than either outboard boat, at both idle and wide open throttle. Even more annoying, the small, high-revving engines of the jet boats produce a high-frequency scream. It's impossible to get away from the noise. For example, at a No Wake 6 mph, when the outboard is turning a quiet 1200 rpm, the engines in the Sea-Doo are already spinning at 3500 rpm to maintain the same speed.

- Now if you add a 10hp motor, you can plane the boat. The speed might go up to 15-25mph. This is because the boat is no longer using all of the hp to make a big wave.... As stated above, some motors may be rated at 1/2 - 3hp, but the usable power in these motors is more like 1/2 to 1hp. Without gear reduction, most electric tolling motors really do not produce much additional thrust above about 1hp.

- i have a 14 ft. flat bottom with a 15 hp and i get about 16 mph out of it with two guys and a dog. so you should have enough motor. your motor could be angled wrong, if the boat is flat the motor should be at a right angle to the hull. if it is anlged up too much you will never get on plane.or most boats, 15 mph +/- or so is enough for it to run on plane. It's important that you run the boat with just you in it. My 14x48 ran so fast with just me in it that it would chine walk a little bit. I never GPS'd it, but it was fast.

Timing a Mercury Outboard Motor You must have a dial indicator and timing light to properly adjust the timing of your outboard motor. You will also be required to use some type of spark plug gap tool. See resources for boat maintenance tools. Locate the flywheel. Remove the cowling cover on the outboard motor's power head and detach the spark plugs.

- “Boats have propellers, something down in the water, and the drag slows down the boat when the motor is off. The hull creates water resistance and so motorboats stop much faster than jet skis. PWCs are very different than boats. There is nothing underneath the hull.

How F/A-22 Raptors Work Fighter jets use the afterburner to fly faster than the speed of sound for long periods, but it decreases the range they can fly without refueling. The F/A-22 is the first American fighter aircraft with the ability to supercruise, or fly at supersonic speeds without using the afterburner. In early flight tests, it sustained speeds of Mach 1.5 -- that's one and a half times the speed of sound -- without using the afterburner.
