Help with 4 blade prop

[tx_swordguy]

Have a four winns 200 horizon 5.0 gl-f with SX lower unit ratio 1.60 current prop is 14.3x21 3 blade at WOT rpm is 4600 range is 4400-4800 . I was looking at 14.3 x19 4 blade props what performance should I expect or should I look at a different size or pitch? Thanks

I think you are in the right place with the 4 blade . . . as you add blades you generally need to give up a bit on pitch. Since your RPM is right within spec, your 3-blade 21" pitch is the perfect reference point.

Expect: a better whole shot, lower planing speed, better cruise economy, beer for life, and a slightly lower WOT speed.

I'll second that.
