Help with Triton V186 Magnum top speed

[dary0362]

Hey guys,

Purchased a Triton v186 Magnum (aluminum hull) with a 4 stroke Suzuki 140 hp, had it out for the first time today. It has a top speed of 43 MPH, which seems a bit slow to me, based on posts here on BBC as some of these boats hit 60 MPH with 150 hp's. Here are the specs:

-5700 RPM WOT
-operating range is 5600-6200 RPM
-Marine Trophy Plus stainless steel prop, 24" pitch, 13 7/8" diameter, 4 blades
-Engine mounted in the second hole from bottom
-Appears to be a lot of water "spraying" when at WOT

Anyone have any prop recommendations for a faster top end speed? Thanks! Dan
