SOURCE: I have a Mariner outboard

In order to disconnect the gearshift linkage from the gearshift operating handle, a safety clip was rotated about 90 degrees clockwise. Once in this position, if you pull the safety clip towards you, it comes completely out, which then permits the gearshift rod to seperate from the operating lever.

SOURCE: gear shifter for 40 h. p. mariner outboard

With your lower unit off have someone shift the engine into forward while watching the gear shift select shaft's rotation,let gearshift remain in forward,now place your lower unit in forward and reinstall. In the future just put engine in forward when installing a water pump as there won't be a need to move gearshift

SOURCE: diagnostic code P1336

It means both cam sensors are outIf you get this code, the first thing to check is your distributor especially if you have an imported vehicle. Look for signs of oil in the distributor which can contaminate the signals being monitored by the ecm (engine computer).Check also the wiring leading to the distributor and see if the wires are properly insulated away from hot exhaust which could burn the wires. Do these checks also on the crank sensor itself whether it is located in the front of the engine or at the flywheel at the rear of the engine. Ditto for the cam sensor of syc.

SOURCE: Mariner outboard motor starts runs, then fuel

If you have carburetors your float is stuck. It can happen more than it should and if it is a smaller engine, laying it on its side can cause it.
You would have to look at the float and imagine which way to lay the engine down in the future. The float could also be bad. You would take it out and float it in Gas, not water to see if it sinks.

If this is a big HP outboard and injected your fuel regulator is bad.

I have a late 70s 28hp Mariner Outboard, appears shift linkage has broken just below the motor where it connects to the rod that goes to the foot. How do I repair it with out moving the motor?


talk with a mariner service center
get a workshop manual for the outboard
with many outboards the selection rod comes apart with the bottom section as if you were replacing a water pump
see if you can undo the top section and let it fall out the bottom or lift the broken section out past the motor
talk wit a service center first and get some ideas

I have a 1986 115 mariner outboard motor. it idles well but wen exellerating it seems like apower failer. You do smell lots of petrol fumes


Since a lot of these question go unanswered I'll just tell you in my very amature opinion that these old engines use rubber diaphragms to get the pressure to move fuel and air. Rubber gets old and cracks and will pass fumes. My guess is therefore the "fuel pump" or similar. When was the last time the motor was worked on? If you google hard sometimes you can find a rebuild kit for a popular engine. It is not by accident that marine mechanics can be sought after and a little spendy.

I have a Kohler 12.5 KW marine generator on my houseboat that has a problem I was hoping you could help me with. Specs: Kohler 12.5 KW 79 CID 23HP Mfg date 9-10-96 Gen Engine Serial # 06919 L-29-R


there are some magnets behind the flywheel to cause the battery charging system to recharge the batt. sometimes they come unbonded/loose from the flywheel and cause the engine to become hard to turn. I would start there first.

1979 mariner 80 hp outboard engine carburator flooding over with fuel


It sounds like maybe the float is sticking open on the carburetor. Check the bowl and needle for debris. The float may be worn out and needs replaced, or another part is bad. if nothing else, put a shut-off valve in the fuel line to stem the flow when the motor is not running.

Mariner 4hp outboard can't get engine off casing


the drive shaft goes down through the water pump impeller and I suspect that the problem will be in the pump
the impeller is rubber and if run dry will melt the rubber into the housing and bind up the shaft
Brute force is a last resort so get all the information you can from a service dealer mechanic
