I have a 50hp 4cylinder merc that i'm going to run a jet on this spring. But i need help deciding what type of prop and pitch to run when i run the prop lower unit on it. my boat only weighes around 350ibs i'm trying to find a chopper syle prop to really make the boat scream up and down the river. I love playin and doing a little fishing after the whites run is over. i don't have a clue how to decide. I've only ran a 25merc on the boat. the 50 should need a high pitch prop to keep the rev's down and a chopper should keep it from blowing out in tight corners on the river.
 
really thought i'd need more prop i have a 25merc rightnow and run a 10.25x13p on the boat.which pushes it like 27 or 28 mph righnow
 
I think the main aim would be to get the motor running within the recommended rpms which is between 5000 - 5500rpm for a 1980 4cyl 50HP.So which ever prop takes you to that is the one you need.You'll need a tach to determine your rpms. Good luck.
