I'd be more worried about what was done to the motor to "hop it up". Don't let the rpms scare you, Mercs like to twist up. 7000 rpm is about max for a ski boat/pleasure boat motor. I've spun "race" 2.5's to 9000. The race 2.0L motors will go 12000. They don't have too long of a TBO at that level. Something like 50-100 hours depending on the rings/type of cylinder wall and reeds
