Seal of Approval
Nothing ruins a cruise like a trip to the engine compartment, especially if it's tighter than Dad's pants after Thanksgiving dinner. If you're trying to reach the impeller, there's an easier way to remove or replace it. Speedseal is an impeller replacement cover that's removed simply by unscrewing two of its four bolts. Rising above the seal's surface, the bolts are located by touch and screw off with just your forefinger and thumb. The inset O-ring seals onto the pump flange, and the recessed area fits over the impeller, leaving space for the impeller rotation. Price: $59. Contact Speedseal at 800/675-1105, www.speedseal.com.

WAAS the Diff?
It can place a boat within five meters of a waypoint anywhere in United States waters and 200 miles offshore and eliminates the need for a beacon receiver and antenna. What is it? WAAS-and Si-Tex incorporated it into its GPK-10, an 18-channel GPS receiver. The GPS signal won't be interrupted by most nearby electronics, so the unit can be mounted almost anywhere. Its antenna and receiver are housed in a single waterproof unit. The GPK-10 interfaces with charting systems, track plotters, autopilots, and other NMEA 0183 systems. Price: $299.
