I have been looking around at different propellers for my force 50 because i cant seem to get on plane with my fishing gearand 3 guys unless 1 or 2 guys go in front to get the bow down. It has an 11 1/2 inch prop and the biggest prop i found was a 13 1/2 inch prop going to a bigger prop would this help me get on plane faster or go faster? Also any suggestions on prop manufacturers?

89/50 hp.Guessing you have a 15/16ft.
Need to know what RPM's your running at WOT.
1-2 people 8-12 gal gas (built in tank)small cooler and some fishing gear.
3 people and gear is probably too much weight.
You probably need to go down in pitch not up.
The motor has a pin in the back that adjusts from front to the back.Moves the motor in and out.Try moving this pin.
How fast does it go when it gets going?
Do a compression/spark test.

the boat is a 17 1/2 ft aluminum(bluefin spectrum). I dont know what the rpms are at right now but it is the stock propeller. With just me it runs 26 mph with 2 people in the boat it runs about 23mph and with 3 people in the boat it will go 20 mph. In the spring i tested compression and i think it was like 135 psi in each cylinder.
