Top Speed 200hp Mercury

I just spoke to the guy who I bought it from and he said that he did change the prop to a heavier prop.

I have to check the RPM's I didn't take notice when I had it out Saturday.

Also Franco, when ever I start it the engine I have to hit it in gear as soon as the engine kicks in otherwise the engine will shut off. In other words it doesn't idle well. When I run the engine for a while and stop the engine will idle for about a minute then shut off??? What gives??

I'm new to boating, and appreciate the help.

Thanks

ps. How do you post images in your messages??
