Outboard manufacturers are now recommending that engines be mounted higher than the old standard, provided boat speed justifies it. In fact, a growing number of boat builders are building their faster outboard-powered boats with transoms 1″ to 3″ above the standard height (usually 20″).
Setting the Outboard Motor Height If the outboard is too low, it creates excessive drag, which cuts into speed and fuel efficiency. If it’s too high, the propeller tends to ventilate, losing its bite on the water and blowing out while turning and in steep seas.
Thereof, How do you install an outboard motor support bracket?
Also to know is, How do I know if my outboard is too high? Too high usually results in low water pressure, prop letting go in turns, or lack of bow lift are usually the telltale signs. Sometimes porpoising is caused by too much bow lift and dropping the motor will give it more bite and make it worse.
Subsequently, question is, How do you know if your outboard is too high? Too high usually results in low water pressure, prop letting go in turns, or lack of bow lift are usually the telltale signs. Sometimes porpoising is caused by too much bow lift and dropping the motor will give it more bite and make it worse.
Also, How far below a boat should the prop be?
eight to 10 inches
How far below the bottom of the boat should the prop be?
If you have a short shaft motor, the top most part of the transom and the lower most part of the boat should be about 15 to 16 inches. For a long shaft, I think 20 to 21 inches is correct.
How do you mount an outboard motor?
How low should an outboard motor sit?
For a propeller to best satisfy particular boating needs, the engine must be attached to the transom at the correct height. Over the past 30 years, industry standards for transom height have been developed: 15″ for “short shaft” engines, 20″ for “long shaft” engines, and 25″ for “extra-long shaft” engines.

Should outboard motor be up or down when trailering?
Traveler2586. If you search the web on how to trailer your boat & motor ( and IMHO, you should) I think you’ll find that small motors (5 – 15 hp) can be trailered down IF your trailer offers good ground clearance; larger motors should be trailered up with a good transom support.

What is an Armstrong bracket?
Armstrong Positive Flotation Outboard Brackets Whether backing down on a big fish in open water, loading up your boat for a weekend dive trip or just holding your own in a following sea, Armstrong Brackets improve the performance, usability, safety and seaworthiness of your vessel.
Where should the cavitation plate be in relation to the bottom of the boat?
The cavitation plate should be nearly even with or slightly below the bottom. For a short shaft the vertical measurement of the transom should be about 15 inches.
What happens if outboard is too low?
An outboard that is mounted too low will limit your boat’s optimal operation. You can often tell that an outboard is too low if you are experiencing sluggish speeds, poor handling, excessive spray, porpoising, or even water pushing up into the cowling.
