Installing a new prop?

I got a new prop from Eric at OJ props. I have never installed one before so. What do I need to know? Thanks

First thing you need to know is whether you have a tapered shaft or splined shaft.

Here is the procedure in an older owner's manual. To be honest, I have not checked the contact area between my prop hub and the shaft (didn't know about this until after I had been running the current prop for a few years). But I know others who do. May tackle it as a small winter project.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.

Once you remove the cotter pin and nut, i take a 2 x4 and use it as the buffer/pressure distributer behind the base of the prop as i tap it with a hammer. It usually pops off after a few firm taps.

Tight fit between rudder and the shaft so it will take some maneuvering but you'll find that angle where the prop will come right out.

Slide on new prop, tighten nut firmly, and replace with a new STAINLESS steel cotter pin.

You'll likely want a puller to facilitate getting the prop off.

Inboard Propeller installation procedureInboard propeller installation procedure

Push propeller snugly onto shaft taper WITHOUT key in either keyway (propeller or shaft)
Make sure the propeller is snug and there is no side to side movement by gently moving propeller back and forth.
Make a line on the shaft with a non-graphite marker at the forward end of the propeller where it stops up against the shaft taper.
Remove propeller.
Put key into keyway on shaft taper with radiused or chamfered corners (down) in shaft keyway (if propeller shaft keyway has radiused corners).
Put propeller onto shaft taper.
Check to see that the propeller moves back to the forward line made in Step 3. If it does, skip down to Step 8. If not, perform the following:
A: Remove propeller from shaft.
B: Place a file on a flat surface area or work bench.
C: Run opposite end of chamfered key back and forth over file (to remove any burs) with a downward pressure on key until side being filed is clean.
D: Install cleaned key in shaft keyway with chamfered corner side down in shaft (the cleaned, filed side up in keyway).
E: Replace the propeller on the shaft and fit snugly on taper. Check to see if it reaches the line make as in Step 7. If it does not line up than repeat "Steps a. through e".
NOTE: A vice can be used to hold key and then filed, but care must be taken not to tighten too much, causing burrs and irregularities on key.

8. When propeller hub moves to correct position, install propeller nut on shaft and torque to seat the propeller. Install the torque jam nut also, if your shaft is so equipped. Install cotter pin at end of the shaft.

Correct Nut Instaltation Procedure: Install Jam Nut (thin) first than the Full nut (thick) goes on second.

Thanks
I bought the spare prop kit that comes with the puller at the same time that I bought the prop.

Can't get my prop off

I tried to get mine off the other day (keyed) with a prop puller and it still wouldn't budge. I'll try heat like mentioned above. Any other pointers? Thanks.
