I'm looking for the original size of prop for this motor. Currently running a 21 pitch that only allows 4300 Rpms at WOT at 43 mph. The hole shot is very slow and I know it due to the 21. I'm thinking a 17 or 19 might get the Rpms in the 4500 to 5500 as the manual says is optimal for this motor. Any suggestions?
 
There are no specific propellers that are supplied with the larger motors. Either a boat builder or a dealer picks and chooses the propeller they want to use.

You can go to www.yamahaoutboards.com and then go to the performance bulletins section. Try and find a boat similar to yours with a V4 115 Yam on the back and you can see what propeller was used for the PB.
