I have overlooked this thread for several days, I recently idled through a shallow water canal and noticed later that the tell-tale water stream had about half of its normal volume; I dismissed it as a failing impeller. Everone I talked to about it couldn't agree that my 200HPDI with only 44 hours could have a bad pump. A few days ago I disconnected the flush tube and several small gravels and some really nasty looking water came out of the tube. I can't wait to get home today to check the poppet, hopefully that is the problem with mine as well.
Thanks for the info!
