My engine over heated. Once it over heated with stream coming out of motor with looked like anti freeze substance seeping out as well. I turned the engine off so it could cool off. I started it up with the engine cover opened. it seemed to be running good with out over heating. The next day I started with the muffs on the lower intake with the water on. The water seemed to be flowing in and going through the motor. I thought everything was working correctly and normal, so I cleaned the engine off with engine cleaner and squirted the engine with a water hose and took the boat back out to the lake. It started alright and everything seemed fine. I cut the engine off once I tried to start it. It would not start. When I would turn the key, it sounded like a weak battery because the starter would attempt to start and make a clicking noise. Then eventually went down to only making the clicking noise. I called a towing service out to give me a boost. I found out that was an expensive decision. The tow service tried to give me a boost it did not work and the boat continued to make the clicking noise when I tried to start it with jumper cables attached. Maybe I wet something that was not suppose to be wet when it steamed up or when I wet it while cleaning the engine. What made it over heat.......should I replace that anti freeze substance that came out. I would appreciate if someone could tell me what might be going on and what I can do.

Re: Question for problem with Murcruiser 170 4.3

Do you have a Mercruiser serial number? Not sure what engine you have for sure. No year, a 4.3 isn't 170hp, there is a model 170, but it's not a 4.3.

4.3 = V6 Chevy
170 = 3.7 Mercruiser 4 cylinder.

I merged both of your posts together in the same forum. Please do not post the same question in two different forums.
