Title: prop shaft size
Post by: Mike Harry on May 16, 2011, 05:28:44 PM

1986 Advance, what is my prop shaft size? Im looking into getting the dripless shaft seal system......    I guess I need to know the size of the stuffing box hole as well (or whatever its is called)
 
Thanks for any help.

most were 1" use a caliper to measure it to be sure
also check the #s stamped on your prop most likely you will see 13x13 x1" LH
or 13 x 13 x 1 1/8" (if you see this you have an 1 1/8" shaft not 1")

10-4, how about the other size? Any idea on that? Do I need to take off what I already have to find out? I was wanting to get the new part in before I took the old part off........

I purchased a dripless system,  now lets see if its all its cracked up to be.

Where should I route the water injection from? Intake manifold?

When a customer insists on having one of these I prefer to tap into the pressure side of the raw water pump before it goes into the engine, the object is to cool & lubricate the seal, so using the coolest water is preferred.

Would pulling the threaded plug on the recirc pump work? I would hate to drill and tap the pump itself.......

Or should I cut the hose between the raw and the recirc and place a T with adapters as needed?

Didnt that damn thing come with instructions???  I'd go back to the manufacturer for assistance.  If they dont know (or are no help) I'd send it back for a refund...  Your stock packing gland will suffice for YEARS and they dont need to drip so much as to cause any issues in the bilge  :)

Yeah.... thats it!!!!    >:(   Leave me to run the whole thing by myself...    :'(   I mean, what is UP with that!!!!????!!!!????

Seriously, I was thinking you had it in your hands with no directions.   I'm sure all your questions will be answered upon arrival  :)  If not, send the damn thing back and get a refund...  Oops... must've been my inside voice sneaking out again...    ::)

Is there a set screw on the shaft to tranny coupling that I am not seeing? Just trying to cover all bases before the install next week. If there is one, I cant see it, i guess I would have to take the paint off.......

figure out this way
Or should I cut the hose between the raw and the recirc and place a T with adapters as needed?

or better yet study the water flow from the raw water pump to X
then to Y

I have seen these things installed several ways
the quickest but the least desirable is directly from an exhaust manifold drain

or read the instructions again  ;D

Ok, seal installed. Called company and they stated any water except exhaust was good, so I put a fitting in the recirc pump because there was easy access where a plug was.

We shall see what happens. The job was much easier than I expected. With 2 people,  1 outside the boat and 1 in it was a breeze.

Seal worked perfectly, and so did the engine oil leak fix.  ;D

Happy Day! Happy Day!

Almost no water in the bilge now, found some drips coming from the rudder shaft base (hoping I can loosen the bolts enough to lift it, clean out from under it and 5200 under) then re tighten.......
