prop removal

[fakeplay]

I have a 1975 johnson 2 hp (r 2 75 d ) and am trying to get the prop off. Do I have to drain the oil and disassemble everything ? Right now I'm looking at a cotter pin though the prop. Is this what holds the prop on ? I tried taking out the cotter pin and lightly tapping around the prop. I want to remove the prop so I can run the motor in a bucket of water so I can adjust the slow speed , high speed needle valves. Thanks for any info in advance.
p.s. I do have a repair manual but it doesn't address how to remove the prop on this particular model.

Re: prop removal

Forget the bucket, Run it on muffs, they clamp around the sides of the motor, around the water intakes. They are really cheap, and you hook a garden hose up to it.

Walmart sells them.

Once you take the cotter pin off, there is a nut, that the pin went thru, and you twist that off.

then the prop should slide off.

this is it:

Re: prop removal

There has to be a nut, what is the pin running thru?
just a shaft?

How does the pin hold on the prop?

The set up on my engine is, there is basically a bolt running thru the middle of the prop, and the prop slides on, and there is a treaded bolt sticking out, anf you put a plate on the bolt, like a washer, then screw a nut on the bolt, then put a cotter pin in to prevent the bolt from spining.

But a 2 HP may be different.

I have heard of props getting stuck, from not being removed.

Re: prop removal

I am sorry that I can't help you with prop removal. The reason for my post is to suggest that to make the mixture adjustments you are wanting you need to have the prop on and in the water. A bucket won't do. The prop loads the engine and being in the water makes a difference in exhaust back pressure. Mixture adjustments are affected by both of these conditions. A shop manual should have the correct information on removing the prop, and correct procedure for mixture adjustments. You could damage the engine doing it otherwise.

Re: prop removal

Agreed. You cannot possibly do these adjustments correctly running without a prop and in a bucket.
