"OK, I pulled the boat out and power washed the OD and bottom. Now it doesn't over heat which is a good thing. But, it will not rev properly. I had a 14.5X 21 prop and the engine would only turn 2000 RPMs and then seem to bog down. We put a less pitched prop on and now it turns 2700 RPMs and then bogs down. The mechanic (supposed to be the best in Baltimore) showed up this morning and checked timing and timing advance and everything is good. The bottom line is he did not know or have any idea why it will not rev up. The mechanic said it idles perfectly and gas is not a problem. If anyone has an idea please post it. Thank you, Bob PS- Prior to all these problems, it would get up and plane with the 21 pitch prop without any problem."
