On my Kenner18v the livewell pump seems to get a vapor lock or
something very often. I've heard this mentioned before. What's the
solution for this? A stronger pump? Not sure what's really
happening. A slug of water caught in line that makes it hard for the
pump to get rolling again or what? Do I need bigger diameter hoses?
The pickup screen is not clogged.

Usually this is caused by a "loop" in the hose trapping air between
the pump and the tank. The hose needs to have a steady rise from the
intake to the outflow into the tank. Also ensure that the pump intake
is "always" underwater and not exposed to turburlance while underway,
esp. at high speed. Without seeing your boat it's hard to pinpoint
the trouble, did the system EVER work right? Any recent changes? New
system? Follow the pump installation instructions?
