My mercury 150 XR2 Black Max had sit for about 6 months, when I cranked it I had no stream coming from the little tell-tail port. I replaced the impeller and it seemed ok. Well it sat for about another 6 months, so really maybe an hour of running during that time, and now I started it a couple of days ago, it was running very rough and would not run at idle for any period of time. I put sea-foam additive in the tank, started it. I had to choke it to keep it running for several minutes and I let it set overnight. The next day it started right up, it would idle but a little rough. I cleaned the plugs and it is running much better now but the tell-tail stream quit spraying. I removed one of the thermostats and there was no debris. I pour some water into the tstat hole, put the tstat back in, had a good stream for a few minutes then it stopped spraying again. Do I need to replace the impeller again or what?<br />Thanks
