Martec Folding Prop

[jpmarshall]

Greetings All,

I removed my 28 year old Martec folding prop and sent it in for a rebuild as I was having problems with vibration and slipping out of gear in forward. The blade size was 13 X 8 RH and they replied that this was oversize for the A4 and are recommending a 12 X 6 RH. I have read throught he other posts and I am still not clear on whether this is suitable or not for a 1979 C&C 27 Mk III.

Comments???

Thanks

My Martec folding prop is 12 X 6. It's on a Tartan 34 & pushes her to hull speed at about 1750 RPM. It tops out at just under 2000 RPM.
