The R&D Cavitation Fighter Pump Sleeve eliminates the “square edge” transition between the transom plate (155mm id.) and the pump liner (160mm id).

The Cav-Fighter Sleeve installs between the two stock parts to blueprint a ramp transition from the transom to the pump liner. When water gets pulled into the pump, the water boils (cavitates) as the impellor is only a half inch (.500”) from the square edge.

Field testing confirmed by eliminating the square edge the Cav-Fighter Sleeve reduced cavitation on holeshot acceleration and in hard turns.

The sleeve is machined from billet aluminum and anodized for corrosion resistance. Picture shows red anodized Cav-Fighter Sleeve and sleeve installed in the stock SVHO pump liner.

NOTE: Do not use with stock Solas prop Part # YV-CD 13/18. This prop requires setback modifications of .120" to clear sleeve.
