Do I go with the same dimensions ? My aluminum prop is 15x19 and seemed to do fine but I bent a blade . Dude on Craigslist has a stainless for $150 that will fit but it is 14x19 . I gotta admit it's hard to know if I should stick with a 3 blade aluminum , a four blade aluminum , or a stainless . It seems there's no definitive answer . Any help is appreciated . |

How did your last prop perform? Were you hitting the maximum recommended RPM range at WOT? If so, going from a 15x19 AL to the 14x19 SS prop will slightly increase the RPM. Going down in diameter increases the RPM but going from AL to SS typically decreases RPM slightly. |
