I have a 4.3 liter Mercruiser Alpha One I/O and upon throttle up, at 1700 rpm, i lose "thrust" and the boat slows back down while the RPMs continue to climb. There's no clunk or any other sound that I can hear other than the engine revving up. When I bring the throttle back down, the prop seems to reengage and continue along, just as long as it stays below 1700.
On the advice of a local mechanic, I removed the prop and didn't notice anything out of the ordinary as far as I could tell. Don't see any metal pieces or shavings, and it doesn't look stripped or damaged. I assume any damage in there would be obvious.
This first happened at the end of a day on the lake while I had the throttle wide open for about 5-7 minutes. Engine temp was fine, oil pressure had been running higher than normal as a trend and all fluids are normal.
On a side note, my blower stopped working as well. Most likely unrelated I think but it happened just about the same time.
Thanks in advance for any help!
