2005 Mercury Prop advice

[TLB2]

Hello Im new here, I have a 2005 Mercury 115 ELPTO on a G3 1966 CC boat. The boat came with a 4 stroke but the previous owner bought the boat for the Yamaha. I bought the boat . I installed the Mercury with a CMC jackplate. I have a 13 1/4X17 Stiletto on it now. Im running at 36-38mph 5600 Rpms. It seems to be hitting a rev limiter. Do I need a 19 or 21 pitch? The boat will be used on the flats inshore fishing. Thanks

I have a Stiletto 11317, will a Stiletto Y1319 off a Yamaha work on my 05 115 Merc 2 stroke?

Re: 2005 Mercury Prop advice

Since the prop charts in the iboats prop section list the same props for the MERC and Yamaha, and both have 15 tooth splines, I would consider that a clue.

But, since I've not tried putting a Yamaha prop on my Merc, I couldn't say for certain.
