hey fellas took my rig out today test run as follows started 2.5 below no good prop would'nt bite had no bow lift 2nd run 3.0 below prop bit alot better 3rd run 3.5 prop bit almost the same as 3.0 below water pressur never dropped below 12.5 psi water pressure is not an issuse top speed 58.5 was the best. keep hitting rev limiter. am i over trimming . rooster tail is no higher than the cowl . boat run flat out and seems like it wants to go. should i have gone w/ 25p instead of 24p coming from the 23p which i was running
