PROP CLEAN UP

Shaft before sanding

After clean up

As it is now, I have to loosen the shaft collar to get the prop off.  Not a good situation.

The 16 x 12, 3 blade prop cleaned up and ready to go back on.  You can have a 2 blade or a 3 blade prop on a P35 but not a folding prop.

 

 

 

 

 

 

 

 

SHAFT CLEAN UP

The 1" x 32" shaft is a little pitted in places but it cleaned up nicely

 

COUPLING LOOSE & PYI OFF

Don't event think about doing this with the fuel tank in place.  Save a year on your life and pull the tank.  I have about 3/4" to play with on the shaft length.  I had to re-drill the collar shaft set screw holes.

Why aligning the shaft to 0.002" makes no since

Haul Out 2000

When I pulled the engine I removed the prop and had it cleaned and balanced.  I removed the 24 year old shaft and cleaned and inspected it also. While everything was apart I replaced the Cutlass Bearing. Listed below are the details.

The Stainless Steel Shaft

The propeller was removed and the shaft was pulled out through the stern tube.  It had some wear rings on it due to the old stuffing box. Once cleaned up, it was in good shape.

The shaft was SS, 32" x 1.0."

The Shaft Coupling was 4" in diameter, 4 hole pattern with 2 each 1¼" x /16" set screws. The coupling end keys were /16" x 1⅞"  long.

The Bronze Propeller

As can be seen in the first picture, the zinc was gone but the prop was not really in bad shape.  It didn't have any barnacles on it.  The SS cotter pin was removed and the SS nuts were unscrewed.  The rudder was placed full to port and the prop was worked off.

The 16 x 12, 3 blade, right hand propeller was reconditioned by Bobby Soles of West Palm Beach, FL.

It was stamped with 16-12, #BSS22227.

Prop end keys 5/16" x 2 ⅛" long,   SS Nuts (2 ea) were ¾". The zinc was a P 3 & 4 from CAMP COMPANY, St Petersburg, FL.
