I have mine apart riight now from 38 #150 and am re-doing all of the shaft hardware, stuffing box and hose etc.   The shaft O.D is 1,250" and the I,D of the factory "Knobby" stuffing box is 1.750" which leaves a void of 1/2" to fill.  The correct size packing is 1/4" in my case. A quarter inch on each side of the shaft.
Best,
Brian

thanks Brian.

Just went through this process this Sun on my #67 1983. When originally unscrewed and removed the packing, I found 7 pieces of 1/8". Thinking this was not correct, I went and purchased 3/16" which I though I read somewhere on this board. Well putting in the Teflon Flax in on Sun, I had a real hard time getting the Nut to start back on after putting in the 1st out of three pieces, which is the norm. I put 1 piece in, then run the nut up on to seat it in, then unscrew to put in the second in. The second one would not go in, even with pushing in with a small screw drive. I took it all out, and found 2 more pieces of 1/8' in their. Once I finelly got them out, I was able to put three pieces of 3/16". One step closer to launch.......

Previous Owners!  I'm not sure which is worse, the work that the previous owner has done or the work done by the (cheapest) yard that the previous owner had done.  The "only" reason I would ever consider a new boat is to simply avoid the dreaded "P.O."

Well then you have the dreaded warrenty fight with the manufacturer which I have seen a number of friends go through.

..or buy a new boat that the manufacturer decides to go Chapter 11..

[Tom Fuhs]

You guys are absolutely correct on those points and I'm sure there are others.  I should have worded that better.  We'd never actually buy a new boat.  Lot's of reasons why, not the least of which (for us) is there is no way we'd afford the boat we'd want.  But there would be the benefit of no hidden skeletons courtesy of the PO.

Venteux has had 3 owners. The 2 prior to Darlene and I were engineers. Need I say more.

Ahhh!  There's my problem.  I'm an engineer, and my previous owners were decidedly not. ;)

Tom:
The way I learned to figure packing size for a stuffing box is to measure the Inside Diameter ( I.D ) of the stuffing box gland nut and measure the Outside Diameter (O.D.)of the shaft and then subtract the two and divide that number by two (  I/2 the difference equal the packing size needed on each side to take up the space)   Works for me and it makes sense.  On my C/R 138 # 150 with the original "Knobby" nutted stuffing box the packing I use is 1/4" .   They may have used a different stuffing box on other boats ? 
Best Regards,
Brian
