cross reference of props

[Reggie B]

I have a black max 150 and currently have a quicksilver laser 2 A41 with a 21 pitch. Need to replace and get a spare but do not know how to cross reference so that I may replace the current prop with another brand. Help?

right on this site you can find all you need - just stick with 21 pitch if that is working correctly for you. And just fill this page out and it will show you others.

Props are all not necessarily alike. May be of "like kind" but not necessary alike. In particular blade geometry (including rake and if so how much and where), ported or not, and cupped or not. Those three things can make a "generic" 14 1/4x21, a possible miss on satisfaction. Obviously you can distinguish SS from Alum, 3-4 blade type things. Best thing to do is replace with what you have and then you are sure.
