Inboard Issues

[Mike Goodwin]

You need a prop puller , looks like a gear puller .
You can make your own if you cant find one to borrow.
2 pieces of 1/2" all thread rod about a foot long , 4 nuts and washers .
2 pieces of heavy metal , one with a U shaped hole cut out of the side and holes drilled for the all thread near the ends .
I draw it for you after dinner .
The size and pitch of the prop are embossd on the hub , something like 9x9 or 8x7 , look for it .

Figures aren't on top of my head , nothing is anymore , but the math is simple enough and I'm good at simple math and I know a knot is 6080' , but where are my car keys?

OK, quickie sketch .

Put all thread through small holes , notch goes behind prop and plate with no notch goes against end of shaft. Tighten evenly on nuts until you have a good strain then whack it with a wood/leather or rubber mallet ,tighten some more and whack , repeat till it comes off .

any ?

Whack the puller , not the prop !

Mike, many thanks! I get the concept methinks. And it looks like I may be able to borrow a real prop puller...

I finally found the coupler.
It is a Vetus Uniflex model 1225 for a 25mm ( 1") shaft .
Allows 2 degrees of mis-alignment .

Sells for $431 , I'll take $ 250 . In the box with instructions .

with a 4" connection for Hurth, Velvet, TD, ZF, PRM and other transmission makes.

If you need an adapter flange, they are listed here and run $110 - $149 ;
