Mercruiser aluminum 3. 14.25x19 4. 5300 rpm (verified) 41-43 mph (gps verified) 5. Mercruiser Chevy 305 2bbl 210hp 1995 alpha 1 6. 1995 conquest 202 23' 3300 lbs l for meaningful response to most questions. 1) Performance issue you are trying to correct. 2) Current prop manufacturer, model, aluminum or stainless as a minimum. 3) Current prop diameter and pitch (required). 4) Wide open throttle RPM and speed with an average load (very helpful) 5) Engine/drive make, model, year, and HP 6) Boat make model, year, length and weight
