I am not a boat mechanic, but your 200 should be spinning that 21 close to max RPM. Your Tach could be bad also. I would get it in to a good mech, Bret Halstrom in Lehi is who I use, but have your motor checked. If you were turning only 3000 at Mead, you have something wrong with the motor !!! My 21 Turbo, on a 175 Merc spins at about 4200 on Utah Lake !! That is on a 18 ft. Skeeter Walleye boat. Have your motor checked !!!
