Ultra 28 Stealth
 

I have a 01 28’ ultra stealth with 625hp. Was trying to see what prop size and speed should I see. Thanks ahead for any info.

I have never been in a Stealth, but I have been in lots of similar West Coast boats. Assuming it has a 1.5 ratio drive, most likely a 28P Bravo 1 and around 70mph

Thanks. Yes 1.5 drive. Do you think of going with an imco lower unit would it help, make a difference and pick up mph. I feel the boat needs more lift so it has less drag

Need more info. What prop are you running now? What speed and RPM @ WOT? How does the boat respond to trim? Is it a MCOB which is very bow heavy? How far below the hull is the current propshaft?

I appreciate the help. However boat is in storage. When I get it out and get the info I will get back to you. Thanks

Quick search i saw one for sale with 525efi 1.5 bravo and stated had a 28” bravo prop. That's all i have for you. Maybe cruise the west / midwest boat sites ?

Aye, hit up River Daves Place.

K thanks for the info

G502,

Absolutely no experience with your hull, and I have no idea of any similarities, other than size and similar HP....

I'm in a PowerQuest 280 Silencer (4800lb, single step), powered by a 496HO w/ an M1 Procharger and Whipple stage 2 tune. ProCharger advertises their 496HO kit at 615HP, so I figure we're in the same ballpark. With a 1.5 ratio B1 outdrive, we are turning a Bravo28P prop and running about 76 MPH GPS, right at 5K RPM.

Offered as a point of reference.

Thanks. Brad.
