SR4.7 with yamaha50hp what pitch???

[jpn]

I am getting a new 4stroke 50HP outboard yamaha for a 4.7m rib. My problem is the engine dealer in my country doesnt know what pitch prop to send with the motor....and I also have no idea....

Hope someone can help out here...I will have 80liters of fuel and 3-4persons on board regularly....

Also do you have any idea what speeds should I expect????
