"So last year I had a small overheating problem, if I was stopped or went slow too long, it would heat up to 220-230, and when I accelerated, it would go back to 160.
This year, first time in, it overheated after 10 minutes warmup at the dock ! So I went out figureing it would cool down. Then blue smoke started coming out ! So I shut down and got towed and went home. Then after it was cooled off, and I added 2 quarts oil, I fired it up, and it might be OK. The I went to work to try and figure out the problem. First water pump, removed, seems fine. Then thermostat housing, looks OK, was going to replace anyway, but I wanted to check water flow.
Here is where it gets interesting. If I disconnect the hose going to the stern drive, and put my house water hose in it, and turn on the water, it comes out the water inlet by the prop pretty good. If I put the adapter on the engine for normal out of the water running (where the water was just coming out), and turn on the hose, nothing comes out the other end where I just had the hose ! Then I remove the little plates on the water intake, and a bunch of hard rubber pieces fall out. So I remove them and think I solved the water flow (even though now I need to figure out where that rubber came from) and still same water flow problem.
HELP ! BTW, this is my first year of boating, last summer I bought it, used it for 8 weeks, winterized it myself (may have done it wrong) and now this ! Any advice is appreciated.
