Hello all,

I am looking for the output coupling flange for a Hurth kbw10
transmission. It came with my 2qm20 Yanmar. The nut got loose and the
inside is damaged. A source for a new one or a used one would be
great.

Thanks,
Jeannette

Hi:

If you strike out here try a yellow newspaper thing titled Boats and
Harbors. Lots of commercial marine stuff. But of help to your late 70s
QM Yanmar, every few months or so I have seen a complete QM
engine/tranny for sale. The last one was two months ago asking $1600
for a 3QM30 running take out including the Hurth. With all the
hurican/insurance boats there should be a few 2QMs around to part out.

While looking around the Boats and Harbor check out the price of the
running take outs. Lets see, rebuild a 30 year old 30 HP yanmar for
$7-8,000 or buy a nice used 900HP 12V71 for about the same price. Go
figure?!?!? Ya think I could break 8.3 knots if I pulled my old 3QM and
droped in a 12V71 replacement?
