hello i have just bought a 1986 17 foot glasstream with a 1986 Suzuki dt 140 still doing some restoration work on it i was just curious if anyone had an idea how how fast this boat should or could run. its rated for a 150 and i had a friend who years ago had the same year model glasstream with a 150 xr6 on it that would run in the low 70's. i understand the xr6 is a v6 and mine is a 4 cylinder but i was thinking it wouldn't be super far off of that. anyone know?
