1988 V20 with 225 Honda

the back of ur boat is floating in water and when you pull out it changes the yaw of ur boat. as the stern goes down, the bow comes up. if you cant hop on the trailer further out the water you should raise the bunks in the rear, or lower the nose roller. wich ever is easier on ur rig. also, are you absolutely positive you are reading mph and not knots? the throttle stop on the motor you were talkin bout, is it adjustable? ur second trip was 315 pounds lighter, same rpm, gained 2 mph. sounds like ur not at wide open throttle. and with only 100 hours on that motor, should you be?
