Expert Johnson Advice

Hi Joe,

I wasn't having a shot at you about your name just a bit upset people thought I was fake.

Not convinced it is the drive shaft as there is no crunching or grinding. I will check the prop after this mornings effort and see if it has slipped ie the line I made has moved.

I will drop the gear oil also to check for metal shavings.

And yes it churned up water in forward and reverse with no movement or drive at all. I then disconnected the two wires to the lower leg which with no current made it stuck in fwd. Again it revved and churned up the water but again to my total frustration have no movement or drive at all.

I don't think it is the way the engine is mounted as it has never been moved even when my grandfather owned it and it went quite well for him.

I also just want to say thankyou to everyone on this forum very much there help and ideas.
 
The sheared driveshaft encounter is a common one but thankfully not a everyday one in the marine repair trade line of work. Even on the mechanical shift models, one will show up as.....

In Neutral = Free wheeling propeller, turning only the prop-shaft. Very light resistance.

In Either Gear = Added to the resistance... Either gear plus the pinion and lower portion of the driveshaft. Difficult to tell the added resistance.

A sheared shaft would NOT result in any added noise of any kind. The break would look like the shaft was somehow sliced in two by a razor, normally just below the top driveshaft splines OR directly under the water pump plate.
 
I agree it is never a bad idea to have a spare prop anyways. Get another prop and hardware and see what it does. If you still have the problem you need to pull the gearbox and give it a complete service.
 
Joe I have heard of just what you are suggesting. It would have to be under the pump, in post #27 he said he pulled lower and saw splines.....
