Time to replace the prop on out dinghy's outboard
. I was wondering what pitch
you have on your outboard
To this end I am thinking along the lines of less pitch
for more push but less top speed. (9.25 x 9 vs 9.25 x 10 or 11)
Of course the details are important. Johnson 9.9 2 stroke
with a 2.4:1 reduction lower end mounted on a 3.1m Zodiac
Cadet 310-AL inflatable
So, what have you got?
From some rough calculations the top end is 15 Kt with the 9" and closer to 20 with the 11". Of course slip is a major unknown but factored in.
