Got some time to play on the lake today for a few hours. We tried a couple of different props my buddy loaned me.
So we tried a Stainless 14 x 21p 3 blade and saw 37mph gps @ 5600rpm...if I tried to trim up the prop would let go. So we swapped that out for a Mercury Mirage Plus, which is a 14-3/4 x 21p 3 blade. Top speed was 44.9mph! Unfortunately my WOT RPM dropped to 5100-5200rpm. I think I need to raise the motor a bolt hole, I can't see the cavitation plate when running. This engine is a tad heavier than the 90hp Johnson
Hopefully with a few more props to try out and engine height adjustments I can get her to run a few more MPH's into the upper 40's with this 200hp Mercury!
I'll post pics on Monday, when I can shrink them down at he shop computer.
Cheers
