It has been successfully installed on many Yamaha, Mercury, Honda, Suzuki, and Tohatsu motors. However, because it is a drill-on application, we recommend checking your anti-ventilation plate dimensions against the stabilizer's dimensions (10-1\/4\" × 8-1\/4\") to ensure adequate space before ordering.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat are the main performance benefits?\u003c\/summary\u003e\u003cp\u003eThe primary benefits are faster planing (improved hole shot), reduced bow rise for better forward visibility, and the elimination of porpoising or bouncing.

Porpoising is often related to engine trim angle, so try adjusting your trim settings up or down to find the optimal position. Improper weight distribution in the boat can also be a factor, so consider adjusting your load before making further changes.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I maintain the hydrofoil?\u003c\/summary\u003e\u003cp\u003eThe unit is made from durable, marine-grade materials and requires minimal maintenance. We recommend periodically checking that the stainless steel mounting bolts are secure. It's also good practice to inspect the unit for any signs of damage after use, particularly in rough conditions, and to rinse it with fresh water after saltwater operation.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is an OEM part vs. an Aftermarket part?\u003c\/summary\u003e\u003cp\u003eThis listing is for an aftermarket replacement, not an Original Equipment Manufacturer (OEM) part.
