I have a new merc 115 optimax with a 19 pitch, 13" aluminum merc prop. This is pushing a 2000 Crestliner sport fish. Since today was the start of the break in, I did a couple laps around waconia changing the throttle the whole time. I think I was out there for about an hour or so?
Anyways, On to my questions...
1.) The motor sounded nice when trimmed all the way down. When I trimmed it up a little, it sounded louder and the RPM's may have been up? It almost sounded like the prop was not completely under water? Like I said, I didnt trim it up alot. On my trim gauge if I brought it near middle trim, that's when it sounded odd?
2.) I ran the motor most of the time between 2000-3600 rpms. Near the end of the time, I pushed it to full throttle, but only for a very brief moment. At full throttle I only got about 4500 rpms and a top speed of 33mph. Since it was such a brief moment at WOT, I didnt get the speed. But when I got home, I checked my GPS and it stated the top speed reached was 33mph.
We went to the flats too. I dipped a tire on the rental car onto it just to say I’ve been there,but it was still pretty soft from winter melt. After seeing some moron in a BMW suv get dragged out of the muck I had no intention of repeating his stupidity.
