Hello;
This is for information only in case someone is interested
I changed out a Michigan Wheel 48 66450A4 17P wheel for a Solas Amita 4 1513-148-15 14.75" x 15P on a 1975 Apollo 19-foot Ford 302 / 888 package.
I installed old style trim / plane tabs to help out the time to initial plane and to keep the bow down. I tried many times to trim the boat while underway and on plane at different speeds with the Michigan Wheel --- results were very little difference if any until finally losing speed and steering control.
After installing the Solas Amita 4 ---> planes much quicker, raises stern / pushes bow down, I can trim 300 to 400 rpm increase and speed increases.
I was never quite sure about the old prop ---- WOT rpm 3600 with Michigan Wheel.
Solas Amita 4 --- WOT rpm about 3900 ---- need to work on power trim skills now that it will trim.
I am also considering removing the trim / plane tabs. I will at least try it with them removed for reduced drag..
I am very happy with the change ---- thank you all for the great information in these posts to help me with my decision to change props and what to look for.
Best Regards
OFM
