Hi there,
My mercury 2 stroke 3 cyl. 80 HP needs a new prop, it has a current SS prop 3 blades 13,5" 19p. He's doing 5000 RPM at about 38-39 miles on my fletcher arrowstreak GTO 161. So I was searching on mercury marine on their "prop calculator". My goal here is to have good allround performance. I found this prop: Trophy plus 13,75" 19P 48-825932A46, I like the idea of having 4 blades and therefore better acceleration and less fuel consumption. This prop seems to get good scores on all available choices (acc., top speed, handling, overall performance, mid handling) but I',m a little bit scared, my RPM will drop too much... Would this be a good choice for me? Perhaps anyone knows a better choice for me? thanks, Foppe |

what's the max rpm for your present engine according to the manual? usually
going from a 3 to 4 blade the diameter is 1/4" less when keeping the same pitch. But it's a gamble. wrote in message oups.com...
