**Pro Tip – Speed Calibration:** Adding heavy stern ballast changes your boat’s running angle, which often causes factory paddlewheel speedometers (like Yamaha Connext) to read 1–2+ mph off your actual speed. For consistent surf waves, calibrate your speed using a phone GPS app or a GPS-enabled chartplotter. On Yamaha jet boats, the Connext screen will often read 13.4 to 13.7 for optimal wave conditions.
