I did a search and didn't find anything that matched my situation.
I have a 21' XRD with a 250 Pro XS 2-Stroke. I'm replacing the engine with a 250 Pro XS 4-Stroke. I've been running a 28" Bravo 1 for 10 years set 3/4" below pad. I have great hole shot and very good bow lift. Top speed w/ fishing load = 83 mph (only ran at that speed once, when I was propping out the boat 10 years ago).
I've been told (a) a 28" Bravo XS would work well, (b) "just plug 6 of the 8 holes in old prop," and (c) "get the Bravo XS but go up one size in pitch."
This will be a fishing prop. I don't race and no longer tournament fish.
Looking for advice from 21' Bullet owners who have made the same engine change. TIA
