Hi, basically it depends on the control box you have. On some you can fit the shift cable in 2 different positions, each one alters whether the cable pushes or pulls when you shift the gear lever. On others it cant be changed(not common). Regards Phil.

SOURCE: Bravo one water on tiller arm

Assuming "tiller arm" is the steering arm (connects to steering actuator and disappears into transom plate, lay on top of engine - not running - and have a friend turn steering wheel, black arm that is coming out of transom and moving is steering arm), problem is most likely the seal on the vertical steering shaft. This shaft connects the steering arm to the gimble ring. Problem can be confirmed by visually checking for water coming from just below the steering arm with boat in water, or residue starting in same area with boat out of water. If this is confirmed to be the problem, repair is quite extensive. Entire transom assembly needs to be taken apart - sometimes requires removal of engine - then the seal can be replaced and the transom assembly put back together. Other items to check in the area would be the wiring for trim sender and limit switch and through hull gear lube fitting (if boat is new enough).

SOURCE: how to install a throttle cable on a 40hp mercury

Depending on the year you will have to open either an access panel on the control box or the complete control box. The rest is just a matter of fishing the cable from the motor to the console. Connecting the ends is relativaly easy, once you open the control box and remove the engine hood the rest will be easy.

Please take a moment and rate my answer............. Thanks

We purchased a near brand new 20Hp Mercury 4 stroke outboard motor (3hr use, the motor is pristine). The tiller will not shift into forward or reverse from neutral. What am I doing wrong?


check that there is not a shift lock to prevent accidental movement and engagement of gears
could be a button to press first or a lever to move
ring a mercury service center and ask them

Are the controls for a 1998 15 HP 2 stroke Mercury outboard compatible with a 2011 30 HP 4 stroke Mercury outboard


If your old engine/control has the same 'options' as the30hp, yes everything is compatible... (Electric start or trim )
The throttle and shift cables are allways compatible...

How do i replace a shift lever on a mercury 6 hp 4 stroke outboard 2006


Hello, is it the external shift handle you want to replace?

Then you'll have to remove the engine block from the driveshaft housing.
To do so: Drain the engine oil.
Disconnect the throttle cable from the carburettor.
Disconnect the start-in-gear cable from the recoil starter housing.
Disconnect the fuel lead at the fuel connector
Disconnect the choke puller at the carburettor.
Disconnect the white and black wire from the stop button at the engine-block and engine wires.
Remove 6 bolts holding the engine-block to the driveshaft housing.
Lift the engineblock.
The shift lever is fixed with a M6 bolt in the front-top of the driveshaft housing. You'll need a new gasket, Part Num 803508-9

Good luck!

How difficult is it to change the shifter cable


1

Take the rubber boot off the gear shift inside the vehicle and lift it up, exposing the area where the gear shift and the transmission connect.
2

Look for the shift cable and the shifting arm. A single bolt and nut connect the shift cable and shift arm.

3

Twist the nut connecting the gear shift and the transmission. Use a socket wrench and remove the gear shift. Use an open-end wrench to loosen the nut holding the shift cable and the shift arm together.
4

Slide off the sleeve on the shift cable and loosen the shift cable at the other end with an open-end wrench. Both ends of the shifting cable attach to the shifting arm in different locations.
5

Hitch the new shift cable to the 2 anchor points on the shift arm using the same bolts and nuts. Reconnect the gear shift to the transmission and push the rubber boot back into place around the gear shift inside the car.
6

Test the functionality of the shifting cable by moving the gear shift in and out of gear.

It will not go into reverse but will go into forward. what should i do first? 1986 mercury outboard


You did not tell us if you have a small outboard or if you have remote shift controls. If you do have remote shift controls you can try reversing the cable ends if it is a 2 cable system or disconnect the cable at the engine. By disconnecting the cable at the engine you isolate the problem to the motor. Then you can grab the shift lever manually at the motor and see if it will now go into reverse. Some remote levers lock out reverse if the choke is engaged or if you are new to this boat there may be a button to push on the throttle to allow reverse to engage.
