21p Tempest Plus on Z7?

[zprice7]

Is anybody running a 21 pitch Tempest Plus on their 150 Optimax on 2011 Z7? I spoke to a prop guy and told him my situation of only running 5200 rpms and he said I should 100% be running a 21 pitch Tempest Plus. That sounds a little small to me but then again I could see it getting me around the max rpm range of my motor. He also mentioned that he hasn’t had any luck with any props other than a 21 pitch on the Z7s. He is the prop expert so I trust him but wanted to see if anyone else has had any luck with the 21 pitch on a Z7 with a 150 opti.

I had a 24 Tempest Plus re-pitched to 23 and it was better. Now run a 23 Power Tech 4 blade with jack plate, big difference!

Mine was best with 22 tempest so as long as you dont over rev it should be fine
