When an engine/boat is overpropped the engine is unable to reach its maximum speed and power output even at full throttle. Conversely when underpropped, the engine will reach full speed but the prop will not be able to demand/deliver the engine's maximum power into the water.
If the prop pitch is too high (higher in inches), the motor may run below the WOT range—called "lugging the engine"—which can also put undue stress on the engine and gearcase components.
If a motor is running too low on RPM, then the boat is under-propped, and is over-propped if the RPM is too high.
Signs that your boat is over-propped or over-loaded
Do your engines seem old and tired and not as “spunky” as they used to be? Are your engines pluming black smoke when trying to get up on plane? Can't reach the governor break point RPM (NOT RATED RPM) of the engine at wide open throttle (WOT)?

Place a pillow or a foam wedge under the drawsheet at the person's back. Position the pillow close against the back to help prop them on their side. Place another pillow or a specially designed foam leg wedge between the person's knees.
Incorrect Pitch: If the pitch is too high, the engine may struggle to reach its optimal RPM, leading to poor acceleration and potential engine strain. Conversely, a pitch that is too low can cause the engine to over-rev, reducing fuel efficiency and increasing the risk of engine damage.
The lower the prop pitch, the better your hole-shot. However, this comes at a price: top speed. The lower pitch makes the engine reach maximum rpm at slower speeds. Conversely, a higher pitch will deliver greater top speeds, but slower acceleration.
Back Propping – back propping can be similar to slab propping. When slab propping is used to support a slab, the loads are transferred to the slab (or structure below). If that slab does not have adequate capacity to support the load, then additional 'back propping' can be applied to the lower levels.
Is there much difference between a loose-head and tight-head prop? There is a massive difference. The pressure of a loose-head is he is getting a lot of weight on his back and his neck coming down from the tight-head. Loose-heads are trying to stay upright, tight-heads are trying to bear down and stay strong.
Is a 19 or 21-inch prop faster? In theory, a larger diameter at the same pitch and RPM will have the same speed, but greater thrust. So a 21-inch prop won't go faster than a 19-inch. However, the increased pitch will increase the top speeds.
Calculated propeller slip within the range of 5% to 25% is typical and acceptable. If slip is greater than 25%, there is likely an issue with the propeller. It could be damaged or just wildly wrong for the boat-and-engine combination.
The Ideal Prop Depth
The general rule is that the center of the propeller should sit about 3-5 inches below the bottom of the boat's hull. This allows for optimal water flow while keeping the propeller deep enough to avoid cavitation.
Sleeping upright is neither inherently healthy nor unhealthy. As long as you're able to rest comfortably and get enough sleep, the upright position might be the best option.
Standing with one foot ahead of the other, shift your weight to your front foot (or knee if you put your knee on the bed) as you gently pull the patient's shoulder toward you. Then shift your weight to your back foot as you gently pull the person's hip toward you.
Unprotected sex (also referred to as condomless sex) is defined as sexual intercourse without a condom. It also refers to when the condom fails (it tears or slips). Condomless sex increases the risk of unwanted pregnancy and sexually transmitted infections (STIs).
