What is the effect on propulsion when the size of a propeller is increased or decreased? Also, what is the effect on the same with an increase or decrease in pitch on a prop? In addition, what does the "+" mean?
Here's my prop history -
14.5" x 17 michigan wheel painted aluminum (on boat now)
14.25" x 21 + viper for omc cobra ss (now gone)
14.75" x 21 viper for omc cobra ss (now gone)
15.25" x 19 mercury mirage (ordered)
13.75" x 21 mercury vengeance (on production donzi 16 classics, recomended by Donzi Corp)
Also, how does your outdrive upper gearset ratio affect propulsion, as a factor of prop size and pitch - Looking for general rules here.
Help me understand and I will reward you with cigars. Just PM me your addy, and a package will arrive soon.
Kind Regards,
Eric
