The engines using pistons within the 4.750"–5.000" diameter range. Because the tool is selected by piston diameter rather than engine manufacturer alone, always verify the bore/piston size of your exact engine configuration.

For Airboat Solutions customers, one of the most important applications is:

Continental 470-Series

• O-470 Series
• IO-470 Series
• E-165 Series
