Dyno Setup Checklist

1) Work Area and Safety

• Clear the test area of loose tools, containers, and trip hazards.
• Verify adequate ventilation and exhaust routing before startup.
• Confirm emergency stop access is unobstructed.
• Use eye and hearing protection during loaded test runs.
• Review communication signals between operator and observer.

2) Dyno System Inspection

• Check hydraulic fluid level and inspect for visible leaks.
• Confirm hose and fitting condition before loading the engine.
• Inspect couplers and shafts for wear, cracking, or burrs.
• Verify gauges are readable and zeroed before beginning.
• Confirm pump/drive components are securely mounted.

3) Model and Adapter Verification

Confirm the engine is matched to the correct dyno model and adapter type before coupling.

• Model 2000 typical range: most outboards 25-225 HP and most stern drives to 260 HP.
• Model 4000 typical range: most outboards 80 HP+ and most I/O up to 575 HP.
• Match adapter by connection style: splines or drive pin.
• If splined, verify exact spline count before final installation.
• Confirm full adapter engagement with no binding at coupler connection.

4) Engine Pre-Run Checks

• Confirm proper cooling-water supply to the engine.
• Check engine oil, fuel quality, and battery condition.
• Inspect throttle and shift linkage operation.
• Secure engine mounting and confirm alignment to dyno input.
• Run briefly at low speed and listen for abnormal vibration/noise.

Pro Tip

Keep a printed checklist at the dyno station and require sign-off before each loaded run. A consistent process significantly reduces setup errors.
