Hello,
Which is the best prop for RV 4 and RV 7A with O 320 engine 160hp
Looking for best cruising speed
Thanks
 
Prop for RV4

I have an RV4 160 hp Ive had 3 different props on it

Senesenich metal 81 in pitch great prop. Very good cruise speed but has a 2600 rpm restriction the weight up front really opens up how much you can carry in the back seat

Catto. Good prop for going very fast but not great at normal cruise power.


Sensenich. Ground adjustable. Best all around. I can tweek the pitch to best cruise pitch. And no 2600 rpm restriction. It performs like the metal prop without the rpm issue.

If you get the right catto prop it will be a good one but if it comes in at the wrong pitch you cant do very much about it ( I know They will make minor adjustments )

The very light props need heavy spacers or you will have cg issues
