Please tell me what you recommend
 

I have a 1989 Baja 270 with the 454 mag I am looking to buy a four blade prop what would you buy

Without knowing current speed. I would say 24p bravo one to start. What speed do you run now?

The boat is now running 53mph 454mag 365 hp

what prop is on it now?

I would need to climb on the back of hydro hoist to take a look I will take a peek next saturday hang tight guys

3 blade I run a 23p Mirage + and I just ran a 21p rev4 yesterday from Bblades that I decided to buy. Boat is a 25 OL with a 502 Mag mpi. With 3 people, half tank, gear I was able to hit 5100 rpm @ 64 MPH gps. Acceleration is awesome from 30-60 and it hops right on plane, also I didn't gain any speed at cruise. I still run about 40 mph @ 3500 rpm. The rev4 should be an awesome prop when the boat is loaded down.

What RPM are you running at to get that 53 mph?

If you don't already have a 4 blade on now, I'd definitely look into the rev4 21p or a 22p bravo 1. I think 24p will be too much prop for the boat, especially with a load.

Ok took a quick look and its a 23p mirage 3 blade the engine is sitting at 5200 rpm

23 Revolution 4 will give you great cruise speed.
Labbed Bravo props are always the ultimate option.
