Reinstalling Prop, HELP

Post by Mark Begg » Tue, 21 Mar 2000 04:00:00


I need some advise on reinstalling a prop on a Malibu.  As some of you
might remember, at the end of the season last year I experienced a 4
mph loss from my top end.  In anticipation of having the prop sent off
and checked, I had my dealer not reinstall the prop after removing it
during the winterization process.  After posting my problem of the
loss of speed from my top end, the overwhelming advise from the ng was
to put the prop back on and check the calibration of the speedos
before sending the prop off.

So here I am,  start of the season.  I pulled the boat out of storage
and performed all the usual dewinterization.  When I went to reinstall
the prop I ran into a problem.  During the removal process last year,
the shop put the nylock nut back on the shaft.  I tried to remove it,
(although not for very long because it was raining and cold).  My
immediate problem was the drive shaft turns when I put a wrench and
try to turn the nylock nut.  I tried putting the boat in gear in hopes
the transmission would engage and keep the drive shaft from turning.
Didn't work.  I thought about putting a pipe wrench on the drive shaft
but decided against that because no matter how careful I was, I am
sure to mar the drive shaft.

Is there a tool that slips into the key slot to that allows you to
hold the drive shaft still while trying to get the nut off?  I'm sure
there's a simple way to do this.  Anyone got any words of wisdom?

TIA...Mark

Two Ideas come to mind.

1. Have someone inside the engine compartment use a couple of wrenchs to
hold on to the nuts that hold the shaft to the transmission while you
turn the nut.

2. Purchase a plumber's "strap wrench" . It's used to prevent marring of
chrome on plumbing fixtures. There pretty cheap.

This is a great way to ruin your prop. You really don't want to warp your
prop with a piece of wood.

I like that plumbers strap suggestion in another response. I never thought
of that one. It should work.

better consider another prop manufacture. Props withstand torques of
excess 300 + Lbs. Far more the you can torque with a 1 1/16 wrench. I
quess you are saying the blades go straight when in motion,(right).

If you consider this safe, take your chances. Sometimes you will win
sometimes you will lose. As long as you have a good prop shop nearby to fix
and explain why you shouldn't do that you will be fine.

When a prop is in motion the torque is distributed across all the blades
fairly evenly. The issue you run into here is that you are sticking a piece
of wood between the blade and the hull of the boat ?  At anyrate, you are
localizing the stress on a thin piece of nibral.  Nibral is soft and can be
disorted.

I've used the wood block dozens and dozens of times.
Just engage the torque on the wrench smoothly.

Or use an impact wrench if you can get it on the nut.

Why would the nut be on that tight to begin with? Every time I have ever
taken my prop off I just hold the prop with one hand and turn the wrench
with the other. Should I tighten the nut more?  Alan Neeper

I just had to replace my prop today.  The nut was not a problem, took
the cotter pin out, removed nut, and attached puller.  Now there is
where I had to put a block of softer than nibral pine wood between the
prop and ground to be able to apply enough pressure on the tool to
remove the prop.  I don't think an impact would 've been a good idea
here and not to mention there is no way I could get it on with the
rudder being right there.

That should work !
Seconded, get a helper to hold onto the coupler flange with "something".
On mine I could probably slide a bar down between a coupler bolt head and
the main body of the coupler half.

Another possibility is an impact wrench, or  "rattle gun".  That should
shake it off and barely turn the shaft.

I snipped the original question. "Mark Beggs said that the dealer had
put the prop nut back on AFTER they had removed the prop"

His question was how to get the nut off with out the prop !
Thanks, Mark

Strap wrench worked.  Thanks to everyone for your suggestions.

Just enough to snug it up...
Sometimes they are a little tougher to get off than on.
