Clogged water system!!
One door opens and another slams in your face!!!
Tomorrow is my last day for testing before our trip to the IOM, I borrowed my father in laws Yamaha 4hp 4stroke to use as an aux engine. I cleaned the carb, jets, tank and fuel lines. The engine started first pull and selects gears fine! Not surprising as the engine has only ever been used as a backup.
BUT, no stream of water from the tell tale!!! I checked the impeller and all good! Nice and pliable with no signs of cracking. Checked the thermostat and it opens as it should in a pot of water in the hob.
I left the stat cover off and started the engine in a barrel, NO water reaching the engine!! I can only assume a blockage in the system. I suspect the engine hasn't been flushed after use and corrosion is causing the obstruction, have any of you guys had the same problem and any tips for clearing?? Thanks in advance, Tim.
Sometimes a little knowledge is worse than none at all....
