RIVA Free Flow Exhaust Kit is installed. Kit replaces restrictive sound suppression system located between waterbox and hull exit reducing backpressure and engine operating temperatures.

RIVA Pump Seal Kit is installed. Location specific molded inserts are siliconed in to the voids of the OE transom plate and RIVA Top-Loader Intake Grate significantly reducing cavitation.

Solas DynaFly Impeller is installed. After extensive im peller testing we found the Solas DynaFly to be the best all around impeller.Billet impeller nose cone included.
