5.8l rpm limit?

[sw33ttooth]

i have an omc 5.8l 351 ford with cobra outdrive year being around 91

wondering what the aproximent rpm should be at on wot. currently its about 4100-4200 if i trim up which puts top speed nearly 40, 1 person full tank of gas.

currently running a 15x19 i believe? michigan wheel 3 blade wondering what a good prop would be to get to 4400 or 4800 depending on my max wot currently running aluminum and my spare is aluminum id like to go to ss and maybe a 4 blade any thoughts would be much appretiated.

4000 - 4400 is spec, you are right in the middle of it.
