Guys, I have a 1998 Nitro 700LX and need to replace the prop on it. Looks like the old one is a Black Diamond Quick Silver 12 3/4 21P. The part number is 2040 21P Quicksilver. The boat is slow coming out of the hole and sort of difficult to come up on plane because of it. I was thinking of going with a Mercury Black Max Sport Series 13 19P to get me out of the hole a little faster. I understand it will affect my overall performance speed wise. Any thoughts or suggestions would be appreciated.
