[C320-list] Changing the prop in cold weather

[fred.lecuyer@live.com]

We pulled ours in September also but didn't get the new prop until December.

Just curious.  When do you prop pullers take your boats out for the winter?  Ours come out in October and prop pulling is a little warmer then.

When we used the MAP torch, we were changing out the cutlass at the same time so I can't answer that potential concern.  My memory is that we were heating the hub of the prop and simultaneously applying pressure with the prop puller. Maybe Jeff Hare can weigh in on this as I believe it was Jeff who gave me the MAP torch idea.

Thanks Allen. Any need to worry about heat deforming the cutlass bearing?

Fred - More heat should work.  My experience is that it generally will take a MAP torch to get enough heat on the prop to break it loose.  The MAP applies about 3 times the heat of a propane torch.  The Association prop puller tool also would be very helpful and we supply an adjustable crescent wrench with the tool!  The prop puller is out on loan currently but should be available soon.  The form for requesting the puller is on the website.  I obviously can't ship a MAP cylinder however.

Maybe one of you has done this before and has some words of wisdom.

I've gotten a three blade prop to replace the original two blade and decided that, as the weather was about 38 degrees F here, today would be a good day to do a job on the boat ;>)

Here's what I did:
STEP 1.     Sprayed PB Blaster in the area of concern and let it sit for
about 10 minutes. 
STEP 2.     Fiddled with the wrenches that I had and found only the vise
grip was large enough to get around the first nut.
STEP 3.    Heated the first nut with a propane torch for a few minutes.....
not enough to make it glow and Rudolph was on vacation anyway, so no help there.
STEP 4.   Applied the vise grip on the outer nut and (yes, I admit it) a
pipe wrench on the inner nut.
STEP 5.  Tapped the vise grips with a hammer while holding the pipe wrench as steady as possible.
STEP 6.   Grimaced. (Did I mention that I had shoulder 12 months ago and now
the other shoulder is jealous?)
STEP 7.   Cursed and told myself I either need better wrenches, more heat or
...... a yet bigger yard bill.


At this point I like to hear from anyone about what size wrenches I need and any other tips on doing what I thought was going to be a simple job.

Many thanks for your thoughts.
