Brief Summary
Ranger has replaced the Z521 which we have tested with the new Z521C, but both boats were designed to handle a 250-outboard, so our test data for the old model should still be relevant for the new model. The Ranger Z521C Comanche was designed to bring a pro level bass boat to the masses, and Ranger outfitted this boat with virtually everything needed to compete on that level. During our test we recorded a top speed of 75.1 mph with the 250 OptiMax Pro XS outboard.
