What should my driveshaft angle be?

What should my driveshaft angle be?

1 to 3 degrees
Ideally, both driveshaft-operating angles will be 1 to 3 degrees. Anything over 3 degrees at the rear axle will shorten your universal joint’s life and could create vibration.

How do you calculate the angle of a drive line?

To calculate operating angles, you must add or subtract the component angles- that is, the relationship of the operating angles between the transmission, driveshaft and the differential, on each side of the driveshaft (drive and driven ends).

What is proper driveshaft angle?

Ideally, both driveshaft-operating angles will be 1 to 3 degrees. Anything over 3 degrees at the rear axle will shorten your universal joint’s life and could create vibration.

How do you align a splined driveshaft?

The male splined driveshaft yoke from the outdrive slides into the female splines of the drive coupler. The position of the engine must be just right to allow the shaft to fit the coupler properly. Proper alignment is achieved by adjusting the motor mounts.

Who invented the stern drive?

During the 1950s, he and fellow engineer Jim Wynne worked at Mercury under founder Carl Kiekhaefer, who was initially dismissive of and opposed to a technology that would later capture 80% of the market. In 1959 Wynne left Kiekhaefer and in less than 90 days developed his own stern drive, which he subsequently patented.

How do you do a proper alignment on an engine?

Proper alignment is achieved by adjusting the motor mounts. The mounts allow the engine to be lowered or raised. The position of the engine tends to change with time. Stringers settle and mounts get soft and sag.

Are the engine compartments of a stern drive boat cramped?

Sterndrive engine compartments may be cramped; however components are neither as tightly engineered nor physically as compressed and densely packed as outboards, which all must fit under a streamlined integrated cover. With both inboards and stern drives there is a fire and explosion hazard from gasoline fuel vapors within the engine compartment.
