Climb Prop
Can anyone tell me what pitch a climb prop should be for a 150HP tri-pacer?

58” is best in my opinion. 56 or 54 will climb a lttte better but cruise and fuel consumption really suffer.

Re: Climb Prop
I've got a 56" on my 150HP tri-pacer, I cruise at 123 burning 9GPH, but also can get off the ground loaded to around 1560#s at high DA from Wilson Bar USFS (1500 ft) without a problem. When I read/researched, it sounded like a 58" for the 160hp, and 56" for the 150hp were ideal, so I went with 56...never tried the 58 though so don't have much comparison, just glad I can still cruise at book numbers without a problem, and I certainly have a shorter ground roll than book numbers.

Re: Climb Prop
What do you have on it now and how much time with that prop on the airframe?

Re: Climb Prop
The prop i am putting on is M74DM-0-56 and the logbook says it was overhaul/ reconditioned, blades re-contour and refinished. that was in Aug/93 and the plane was taken out of service about 100hrs later. I want to install on my PA-22-150.

I will second what Gilbert stated. I have a 58” pitch on my 150hp PA-20, and find it to be a great all-around prop. Your profile does not give any info on you location, and mission. You get off the ground sooner for sure! However, you may not like the speed. Please do report back with your findings!

Re: Climb Prop
Having flown with the 56” and settled on the 58” you will be happy with the climb on the 56” which is slightly better than the 58. My Clipper is probably 150 lbs. lighter than the average PA20 or 22/20 so it climbs better with than heavier aircraft with the extra pitch. Empty wt. 1035 lbs.

Re: Climb Prop
The prop that was on it was a 74DM6-0-50, which i don't believe belonged on the PA-22-150, according to what i can find in the Sensenich prop application chart. The absents of a 6 on my M74DM-0-56 was perplexing me until i found the cross reference indicating it was produce in a different time frame. How am i doing so far, please give me you thoughts.
Thanks
