2006 Sweetwater 2186 with Yamaha 60hp 4 stroke

[lakegeorge]

I just bought a 2006 Sweetwater 2186 with 60hp Yamaha 4 stroke and I was wondering who else has one out there and what prop you swing?
My GPS shows 21 mph at WOT at around 5,800 rpm's
I love the boat and the way it handles but like most people I am always looking for a few more MPH.

Thanks,
