Hi John,
I have recently replaced a shaft and have the dimensions of the taper. Obviously I can’t guarantee it’s the same as yours but my boat is a Corniche 1991 with TAMD41B, also with 20x26 props. As far as it all looks it’s all standard as was supplied new.
If you PM me your email address I can email the drawing over.
Regards,
Lee

Hi John, I have this year removed both my props. I used a hydraulic prop puller and blow torch, they both came of in a couple of minutes. Regards Richard.

Where will you go for the new props?
I had mine redone and the previous owner had removed the “cupping” and I couldn’t get expected speed. I’ve had the cupping added this winter (another £400!) and look forward to trying later this month after launch.

I’d be interested if you could share the taper sizes as I’m looking for a spare set of props. I’m currently running 20x26 four blades and have acheived 27.2 knots at 3900rpm on gps
If you could forward the taper sizes to gwatt20000@yahoo.co.uk i would appreciate it.
Thanks
