Wow, we have a twin out there. We thought we were the only one ourselves. Just gave the boat to my youngest son, has been a fun and inexpensive boat for the past 6 years. With just me and a standard aluminum (M) E 3x15x17r prop we have always had on it will do 41 on calm day trimmed out. The wild thing is My wife, a friend, Myself, 40lb dog, and medium size cooler will always top out at 37mph on the gauge (We are all 200lb plus people too). We even gps'd it a couple times and it's the only boat I have that the dash speedo is dead on. The Rpms are perfect with that prop. Will miss her like I am sure Dorsel will miss his, but that leaves new adventures open in the Glastron family. If you want to see his better our oldest son put on a couple videos of it under the name Glastron Fever at youtube. Would love to see photos of yours and see if anything is different that ours or other Metrics.
