1997 190 pro v, 200 mercury carb’d. New to this boat go sure, not sure exactly how the boat should run, has 12” setback at 1.5” below pad. If I get any positive trim during WOT, my WP drops to around 8-10 psi and have to trim down. Top speed i saw all day was 65 that was running directly into a 10-15 mph wind with good chop on the water, the bow lifted well. Otherwise with calm water I was ruining 59-62. Was running a 23p Solas scorpion, 15 1/4 diameter. Only prop I have at the moment and it is borrowed. Previous owner said he ran a 26 trophy plus to a top speed of 64. I’ve read the 190 is a difficult boat to prop with a mercury having a low RPM range. Any help would be appreciated.
