Hey guys,
Boat is a restored 1978 Cruisers Rally 174 with a 170hp Merc 470. With the current 14x25 3 blade merc prop the boat runs 45MPH (GPS) at 3850 RPM with one person and a light load. I need to get my light load WOT RPM closer to 4200 and get better out of the hole power for heavy loads. I was looking for a 14x23 as a replacement.
I found a 13.5x23 locally that has been remanufactured for about $80. Is the .5" reduction in diameter going to hurt me? Does this sound like a good option to try or am I way off?
Thanks,
-Eli
