Hey guys thought I'de ask the Evinrude guys this also, I have a 96 four winns 170 with a 96 rude 115. I am running a 19p Michigan wheel ss prop. I can only get to 5100-5200 rpms about 42mph gps, If I bump my pitch down to a 17 aluminum I run at 5600 rpm 38 mph. I am stumped as to why my 19p won't turn more rpms, I am thinking about raising the motor and trying that out. Just curious if any of you guys run this motor on a fiberglass boat and what your getting. These number were with me by myself with about 6-7 gallons of fuel on a mildly windy day. Thanks
