proper propeller pitch?

[jrmiah]

Hi, I need to replace the props on a set of twin counter rotating 1998 Johnson Ocean Runners - 200hp - 2 Stroke models J200TXECM / J200CXECM.

I will be pushing a 29 foot C-Hawk 6-Pack SCUBA Dive charter. What would the best prop pitch for this heavy load (people,gear, tanks, etc)? and should I get 3 blade or 4 blade.. thoughts?

Re: proper propeller pitch?

Well, if your talking heavy load 4 blade is usually better. What props do you have now, what is the rated max rpm, and what rpm do you reach when running wide open throttle with full load? That is the minimum information to get any kind of intellegent prop recommendation from. Let us know and a bunch of people will do their best to advise you.
