Your friend with the 3GM30 made a poor choice of gear ratio/prop pitch if he has that problem...

Sounds like he has too much prop pitch for the gear ratio. You can normally repitch a prop by +/-2" with no trouble and sometimes by as much as +/-3". Decreasing his prop pitch will let the boat run more slowly at a given rpms and will also improve torque availability.
