Thread: Ultra 21' Deck

    How much HP are you pushing to get those speeds? 57 MPH just seems slow. How much HP do you think it would take to run about 70-75 with that boat?The Motor puts out 365 HP. I think it would need around 500 HP to get those speeds. John at Ultra said that this motor may have a bolt on Factory Super Charger that would put it at those speeds and HP soon. Currently it would void the Warranty if it was put on, or so I have been told

    This months ***boat mag has an article on an Ultra 27 Shadow...The last paragraph states Ultra may be building both a 22 and 25 foot deckboat with the shadow bottom...May be worth waiting for...

    If you want one of the 21' deck boats that Ultra is making call John at Inland Ultra 909-734-6000.
    He has one in the showroom right now for sale. Around $42,000 I think.
    Also, there have been at least 2 of those deckboats rigged with an outboard and both hang out at Lake Martinez. One is white/yellow/blue and was rigged up by DCB. The other is white/red/black checkers with a 2.5 or 3.0 wacka. That one was built by Tom Papp. The boat also comes in an outdrive version. Tom recently built one with a 460 BBC that did @80 mph.
    The 21' Phantom, as far as I know, is still available at Ultra.
    Nova guy, I have a ton of pics of the deckboat. Go to the media center and search "kwicherbichen" also try at Hot Boat Pics . I have some there too. From what i was told,my nieghbors21 phantom was a one and only built from ultra...Johns not going to build any more.

    I looked at the 21' Deck last week in Norco. Like it a lot, could be my next boat. How do you like the vortec motor? (Out of the hole, top speed etc.) One thing I was wondering about, is how it sits in the water. It looks low profile at the bow. If you are just sitting and floating, it looks like a fair size wave might get you wet.
    We only had water come over the bow once, and it was because I wasnt paying close enough attention when I was idling in to the sand bar. I was turned the wrong way and got caught with a wake that I could have body surfed. After one day, I figured out how the boat needs to be positioned when anchored at the Sand bar to avoid any water from coming in the boat. As far as power outta the hole, its great. It planes out quick. The top speed so far isnt what I thought it would be, but I did notice after the last trip, I did get 150-200 more RPM than the last trip. I think we hit close to 50 MPH up river, with 6 people, cooler, and half tank of gas. I think once broken in in Ideal conditions (2 people, down river, tanks half full, we will be getting 57 mph.. How much HP are you pushing to get those speeds? 57 MPH just seems slow. How much HP do you think it would take to run about 70-75 with that boat? The Ultra deckboat runs low to mid 70s with a stock 502.

    Low to mid 70's with a jet and stock 502? Wow jawdrop I really love the boat. I'll have to wait a few years though. Who knows, the length of time it's taking D&S to do my interior, I may buy that before my boat is complete .

    The Ultra deckboat will run 65 with a 450hp 502. The boat will run 70+ with a 502 502hp motor. The boat with a 502 502hp motor headers setback jet and a divertor runs around $54900. Sorry for the confusion
