1990 force 120 OB prop help

[capricuddy92]

hey everyone,

looking to to replace my prop, i have a 21 foot Baylonie Capri cuddy, with a 120 hp force outboard. It does have an exhaust above water and a spout above the prop. Was curious what you recommend. I have a 19 pitch on but it’s banged up so can’t tell the diameter for sure and there’s no markings. Anyone want to recommend a size for just rooting around our small 99 acre lake please?

You’re likely spot on at a 19”. To be sure really need more details around rpm, gear case and speed etc. But it’s likely the force 120 is on the border where they change gearbox size from small to big. This would determine the prop for it. I know that the merc gearcase changes around this HP and certainly above it.
