Let's look at how to plane an outboard motorboat in a step by step:
- Trim the engine in all the way
- Tell passengers to hold on
- Accelerate gradually onto plane (usually 20 knots +)
- As the boat speeds up and the bow comes down, slowly start trimming the engines out.
- As you trim the engines out, the boat will start to plane
Why is my boat not getting up on plane?
Redistribute Weight in the Boat You may need to redistribute this weight to plane more efficiently. For instance, if you are carrying passengers and too many of them are sitting toward the front of the boat, some may need to take seats in the back or middle if your boat won't get up on plane.
What causes a boat to plane?
As more power (and speed) is applied, lift increases, and the boat, in effect, rides over its bow wave, reducing wetted area and thus reducing drag. At this point, the boat is said to be "on a plane" or simply "planing."
What helps a boat get on plane faster?
By having more stern lift and trim control, this allows you to holds the bow down and stern higher, so the boat will plane out flatter, which will help the boat rise up onto the plane easier, also providing better forward vision from not raising the bow so high.
Will a hydrofoil help my boat get on plane?
Better Performance Installing a hydrofoil allows your boat to get up out of the hole faster and accelerate more efficiently when up on plane. Even at low speeds, you can benefit from better performance because the hydrofoil keeps you up on plane.
How do you plain out a boat?
Tell passengers to hold on. Accelerate gradually onto plane (usually 20 knots +) As the boat speeds up and the bow comes down, slowly start trimming the engines out. As you trim the engines out, the boat will start to plane.

Does waxing the bottom of a boat make it go faster?
Some people think waxing the bottom makes it go faster, but experienced performance boaters know a waxed bottom makes surface tension greater and increases drag.
How do you increase the acceleration of a boat?
Here are some simple ways to help almost any family boat reach its full speed potential.3 Ways to Make a Boat Faster. Reduce weight. ... Reduce Weight. Reducing weight is like finding free horsepower, and many boat owners are surprised how much weight they can leave on the dock. ... Don't Over-Trim. ... Change Your Propeller.
Do trim tabs help boats on a plane?
Properly sized trim tabs can significantly reduce the time needed to get up on plane. They also allow a boat to keep its bow down and stay on plane at lower speeds. As the throttle is advanced, the stern of the boat begins to squat, lifting the bow.
What is better trim tabs or hydrofoil?
1:323:33Nauticus Inc. - Hydrofoils vs. Trim Tabs - YouTubeYouTubeStart of suggested clipEnd of suggested clipEffect also hydrofoils are not adjustable. So the amount of lift increases as the boat speedMoreEffect also hydrofoils are not adjustable. So the amount of lift increases as the boat speed increases. This can cause the bow to plow down into the water reducing top speed and fuel economy.
Does a hydrofoil slow a boat down?
Hydrofoils work to help a boat reduce drag and increase speed. Because water provides resistance to a ship trying to move through it, the resulting pushback can make a vessel slow down, even at peak operation.
How hard is it to hydrofoil?
You need to be able to surf quite well to surf foil. Starting is hard, and you need to start in small forgiving waves with a helmet on. It's a steep learning curve so take your time and be safe. You will need a foil board similar size to your regular surfboard or smaller.
What causes a boat to overturn?
Common causes of falls overboard and boat capsizing include: being caught off guard by a wave or sharp turn when moving around in the boat, carrying too much weight in the boat or unevenly distributing weight in the boat; and bad weather conditions.

What causes a boat to blowout?
Blowout occurs when something causes air/water mixture in the region of the propeller to become sufficiently disturbed that the propeller cannot continue working in “clean” water, but is rather, trying to work through a very soft or light mixture (or a relative vacuum).
What causes a ship to go off course?
Because water currents or wind can cause a craft to drift off course, a navigator sets a course to steer that compensates for drift. The helmsman or pilot points the craft on a heading that corresponds to the course to steer.
How does a chipped propeller affect boat speed?
A damaged or dinged, or chipped propeller will reduce the boat speed drastically due to the water that is not sliding on the dinged propeller smoothly, directly decreasing the speed. Your boat may take a long time to reach top speeds (cruise speed). It also struggles to get on a plane.
Why is raising the propeller on a boat harder than on a plane?
There are some severe disadvantages to raising the boat motor. With the propeller closer to the water surface, it’s more likely to ventilate and slip-on acceleration, making it harder for the boat to get on a plane.
What does a spun propeller hub mean?
Spun Hub. A spun propeller hub will not plane your boat. A spun propeller means that the prop hub has spun inside the propeller. Once the hub spins inside of the propeller, the propeller will spin freely (slowly) and not along with the hub.
What is a spun hub?
In other words, Spun hub usually pulls good to a certain point, and the motor acts as it goes out of gear, the rpm’s skyrocket, but the boat does nothing. AKA “Prop slippage.”. The rubber hub of the propeller is a fortified ring made of durable rubber, which is inserted between the prop shaft and propeller’s inner hub.
Why won't my boat get on the plane?
Here’s why a boat struggles to get on a plane or won’t plane at all. A boat won’t plane out either due to a bad propeller, improper motor placement on the transom, wrong trim position, uneven weight distribution in the boat, low engine performance. However, there could be many other reasons, but primarily those elements will cause a boat not ...
How far should a boat prop be from the pad?
It should be 3.5 inches, not less than 3.25″, or not more than 3.75″.
Why is my boat not planning?
It can be causing your boat not to plane by not giving your engine ample performance.
What are the best tabs for a boat?
The best ones are the hydraulic/electric tabs that you control right at the helm. They are more expensive and you have to install wiring and drill holes inside the boat and this is not really something most boat owners want to tackle so you need to also pay someone that knows what they are doing to do this for you.
Why is RPM important?
This RPM range is important because the most horse power for your engine creates is at a certain RPM and the range gives the boater a general area of RPM’s he can operate his boat at full speed without causing damage to his engine and to give him the most power and best performance his engine is going to make.
What is a hydrofoil?
These hydrofoils look like wings and are designed to help lift the stern of the boat at initial take off which makes the boat get up on plane quicker. They are made of either aluminum or some kind of composit plastic material.
How big are trim tabs on a boat?
The third thing you can do is add trim tabs to your boat. These tabs are flat thin plates made out of aluminum and are usually 12 to 24 inches long and 6 to 12 wide , they do come in other sizes too depending on how big a boat you have and size you need to have them work right.
What happens if you have too low of a pitch prop?
If you have too low of a pitch size prop you will over rev your engine at full speed causing possible damage to the engine. Too high of a pitch prop will cause the boat to take off slowly when you go full throttle from a standing start.
Can you use a lower pitch propeller on a boat?
You can use a lower pitch propeller for better take off, just do not go over your recommended wide open throttle RPM range at full speed. If you have a three blade propeller on your boat you can go to a four or even a five blade propeller to improve on the time the boat takes to get up on plane.
How long does it take for a boat to get on top of a plane?
But the big advantage is in the boost at take-off. A well-set-up boat in the runabout or bass boat category should get on top in 4 to 5 seconds, and the foils make that possible in many cases with packages that previously took 8 to 10 seconds to get up, if they ever made it.
Why are foils good for a plane?
Another plus for the foils comes when slowing down, for example, to soften the ride in choppy seas; they make it possible to stay on plane at lower speed, thus greatly improving the ride .
How to stop wind from hitting your eyes?
Wear eye protection. This will reduce wind from hitting your eyes and allowing you to see better.
Do you need a hydrofoil for a saltwater boat?
Anglers who fish the saltwater flats, where near instant planing is often called for to jump up in a shallow area, can also benefit from the hydrofoils. They're not necessary on a well set-up boat with the right power and prop, but on rigs where the combination of loading, power and prop are challenged, they can provide an affordable improvement in performance.
What to do if your Jon boat won't plane out?
If your Jon boat will still not plane out then you need a more powerful outboard motor or need to take a look at your trimming technique. Alternatively, you may have an underperforming outboard motor.
Why won't my Jon boat plane out?
The outboard is not powerful enough for the boat size. If your Jon boat won’t plane out then it is either too heavy at the bow, carrying too heavy a load or the outboard motor isn’t powerful enough.
How to get a Jon boat on a plane?
How do you get a Jon boat on plane? With the motor trimmed in towards the transom gently increase speed so the bow of the Jon boat lifts up and out of the water. Then trim the motor up away from the transom. When the boat starts to slow stop trimming. The bow will drop and the boat will be on plane.
Why did the captain of a boat need a more powerful motor?
Obviously he needed to fit a more powerful motor to his boat so it could provide the thrust and speed needed to get the boat to plane out. This is a simply fix and may seem obvious but it is surprising how often guys don’t realise that they are either under-powering or overpowering (brings problems of its own) their boats.
What happens when a Jon boat is in water?
When a Jon boat is sitting in the water at rest it has static buoyancy – the water displacement is keeping the boat afloat. As the boat is propelled through the water the dynamics of how the boat interacts with the water changes. As thrust and speed are increased, via an outboard motor, this creates hydrodynamic lift.
Why is good distribution of weight on a Jon boat important?
Good distribution of weight on a Jon boat is essential if you want to get the boat on plane.
Why is the positioning of crew important in Jon boats?
As Jon boats are relatively small vessels the positioning of crew is important as this will greatly affect the boat’s ability to plane effectively. For example, if crew and passengers sit on only one side of the boat then it will not ride level.
Which trim has the best leverage to plane a boat?
Usually full down (In) trim has the best leverage to plane a boat. Not always, but I'd start there.
Do V hulls have trim tabs?
Personally I believe helm adjustable trim tabs should be standard on almost all v-hulls. Passive tabs like Smart Tabs are a good, lower cost, alternative. I would not look upon them as a "fix", although they will always improve planing performance. Throttle necessary, time to plane and minimum planing speed are all improved. With that said, you should be able to plane her as is if all is right. "All" includes, engine, hull, weight, weight balance, propeller match, operator etc.
Do boats take throttle to plane?
Many boats take a lot of throttle to plane, but may have plenty of reserve power for a variety of speeds once on plane. Once she's up and going you should be prepared to back down on the throttle and start to trim up. This takes some practice, but full trim down (In) can be very scary once at speed, and she will gain speed quickly ...
Can a 150 on a 19 get up?
Your 150 on a 19 should have no trouble getting up. As was said, start with the motor down, but be careful because sometimes this will make the bow dig in and the boat veer one side or the other (happens worse with tabs).
