Try and hook up a water supply to the pickup tube-if there's no blockage you'll get a pee stream. Just make sure you keep the engine upright all the time the hose is connected and you'll be able to start it if you want-but you'll get a stream anyway even if it's not running.
Have you still got the sealing grommet in the impeller housing (if it has one) and if so is it worn enough to lower water pressure dramatically??
Assuming it's OK, go buy all the parts M Chappelow lists. It's a false economy doing anything else on outboards
Need spares,consoles,consumables,hire,training or even a new boat?
