Prop ?

[TAKIN IT EZ]

I have a 2001 Mercury 5hp. 4-stroke,long shaft on my 1800 Lund Fisherman I use as a kicker.The motor came with 2 props. 1 is a 3 bladed 8 3/8" dia. with 3 1/2" wide blades.Stamped on the prop is R6. The other prop is 8" dia. with 2 1/4" wide blades,it also is 3 bladed. Both props are alumn. The second one is stamped 8. My question is which prop would be best for trolling? Thanks for any sugestions. Rudey

I'd help you if I had an answer. My guess would be the smaller prop you could run at higher rpm's and you'd go slower. The bigger prop should move more water at lower rpm's. So the smaller one would be better for trolling.
