A vessel's length at the waterline (abbreviated to L.W.L) [1] is the length of a ship or boat at the level where it sits in the water (the waterline). The LWL will be shorter than the length of the boat overall (length overall or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more ...

An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines , where the valves were located below the combustion chamber in the engine block .
Also pushrod engines almost always make less power and torque from a given displacement, compare just about any engine you can find: BMW M3 - 81.875 ft-lb/l, LS7 - 67 ft-lb/l. Also compare the output of the OHC Ford engines to the GM pushrod engines, the Fords have higher torque output for a given displacement.

In British imperial and US customary units, it is defined as 16 + 1 ⁄ 2 feet, equal to exactly 1 ⁄ 320 of a mile, or 5 + 1 ⁄ 2 yards (a quarter of a surveyor's chain), and is exactly 5.0292 meters.
The Waterman outboard engine appears to be the first gasoline-powered outboard offered for sale in significant numbers. [11] It was developed from 1903 in Grosse Ile, Michigan, with a patent application filed in 1905 [12] Starting in 1906, [13] [14] the company went on to make thousands of his "Porto-Motor" [15] units, [16] claiming 25,000 ...
