There is the g/box bolts to remove.On the side of the leg will be a plate that gives access to the gearchange rod.It also has to be unbolted.The rod is a 2 piece item with bolts joining the top and lower part.Undo them.The gearbox should now drop off.If it doesn't the driveshaft may be seized in the bottom of the crankshaft.If this is the case,it could turn into a major fix.Hopefully it isn't.Hope this helps.

I have a short shaft Johnson 6hp outboard, the Jon boat I mounted it on is too deep, and motor doesn't reach water. Is there a way to lower motor? A bracket to lower motor to reach water?


outboard motor manufacturers supply a long shaft leg for just this problem
Talk with your Johnson dealer and check used outboards on e bay
Lowering the whole motor may affect the boat and floatation aspects besides making it harder to steer and start

No water flowing out my 40hp envenrude outboard water exaust port


Plossibly clogged intakes (grim in intakes) or thermostats not opening. I would suggest pulling the lower unit and then your thermostat housing and use a water hose to back-flush it out. Also check the thermostats in boiling water to make certain opening.

Take the cowling off. Also drop the foot. There wil be a stainless linkage rod that runs the length of the motor that you will have undo to drop the foot. The water impeller will be inside a stainless casing that you will have to disassemble.

Water pump not working on Johnson 3.3 outboard 2 stroke.


sounds like you need a new water pump impeller.
to access the impeller the bottom of the motor needs to be unbolted and the impeller is fitted to the shaft, it is keyed so it only goes on one way. ( impeller kits will come with new gaskets,grease.O-rings and a new key ). re-bolt the lower unit and test.

1997 Evinrude 50 HP SPL. I have removed all the bolts holding the lower rnd to the engine, it seems to be hanging up on the shify shaft, and I can't find a way to drop the unit. It drops down about...


Okay this is on total memory. The shift shaft for a lot of those engines goes right up through the pilot shaft and exits just in front of the block under the carburetor(s). You will see the **** linkage arm connected to this shaft sometimes it's double nutted. See if you can slide the lower unit back up to the housing and put a bolt in it to hold then undue the shift shaft linkage, Remove the bolt and drop the lower unit. Be careful of the water tubes and check make sure the rubber grommets are in place in the pump housing not on the tubes. Clean up the pump housing and install the new impeller kit.
Put the impeller down the shaft on top of the impeller plate, lightly grease the inside of the housing the impeller plate and impeller. Then lower the pump housing down to the impeller while turning the drive shaft clockwise lightly push down on the impeller housing. This will fold the impeller blades all in the correct position and provide lubrication to the pump until the water gets into the pump. To make life easier re-grease the drive shaft spline and the water tube grommets this will ad ease in reinstalling the lower unit. be careful to make sure you thread the drive shaft, water tubes and shift shaft all in at the same time. After installation you may find you need to adjust the **** linkage.
