Linkage Rod

snapped gear linkage in lower outboard?

my gear linkage has snapped off in my lower outboard engine so now my engine is stuck in gear, my engine still starts easily but the prop obviously spins, can i plod on using my boat or will it damage my engine do i really need to take the top engine out and change a new gear rod? i've got spare engines but can't be bother to swap. do i really need to swap?

What make engine?? We might get mo specific.

Depending on the make they will run on just happy, or will totally destroy the gears.

For instance- the air-cooled Tecumsh,Clintons had a bendix wire that would break and it would just go in gear and stay there. The chrysler had a little square brass yoke which shifted the gears and if it broke and got tangled up in the gears, they were shot.

The merc had the most bullet proof shifter. Being a round shaft with a bullet nose that ran on ramps to move the clutch dog. They usually suffered bearing failure or rounded clutch dogs.

Many OMC engines had a Large yoke on a pivot that ran the clutch dog along the prop shaft splines. (not counting their foray into electrical shift or wire wound spools.) When this failed -it was usually the pivot pin on the yoke or the yoke itself where it ran in the groove of the clutch dog.

Steering is the term used to the collection of components, linkages and others which allow a vehicle to follow the desired course. The most common steering arrangement is to use a hand-operated steering wheel to turn the front wheels. The steering wheel is positioned in front of the driver thru the steering column. The steering wheel, piston gears, racks and the tie rods are the parts that guides the direction your vehicle.

The two most common types of steering systems are rack-and-pinion and recirculating ball steering. In the rack and pinion steering mechanism, the steering wheel turns the pinion gear which moves the rack from side to side. The rack is sort of a linear gear which meshes with the pinion. This movement applies steering torque to the pivots of the steered wheels thru the tie rods and the short lever steering arm. The recirculating ball mechanism is found in older vehicles and is a variation on the older worm and sector design; the steering column turns the screw which meshes with a gear causing it to rotate about its axis which also moves the pitman arm which is connected to the steering linkage. The rack-and-pinion steering is where the rack-and-pinion gear set is enclosed in a metal tube called the Pontiac Steering Rack and where each end of the rack protrudes from the tube. The tie rod connects to each end of the rack. The pinion gear, on the other hand, is attached to the steering shaft. The motion of turning the wheel is transmitted to the pinion gear which also transmits it to the steering rack. When you turn the steering wheel, the gear also spins, and moves the rack. The Pontiac Steering Rack then converts the steering wheel’s rotational motion into a linear motion needed to turn the wheels. It also supplies a gear reduction which makes it easier to turn the wheels. Normally, it takes about three to four complete revolutions of the steering wheel to make the wheels turn from far left to far right. Lower steering ration means you do not have to turn the steering wheel so much to get the wheels to turn a given distance so the steering gives a quicker response. In the power system, there is a slight difference in the design of the rack. Part of the rack contains a cylinder with a piston in the middle which is connected to the rack. On either side of the pistons are two fluid ports. The power system, though it makes turning the steering wheel easier, adds a new dimension and complexity to the system. To supply high-pressure hydraulic fluid to the steering rack an engine-driven pump is used by the power steering rack.

The Pontiac Steering Rack is not exempted from any damages. The constant wear and tear can cause the Pontiac Steering Rack to leak. In order to ensure that steering is made light and easy there is a need for fluid and if the steering rack has a leak then it will not be able to contain the much needed fluid. Definitely, significant leakage is a basic problem of your steering racks.
