    That engine would likely sink a Flightcraft.

    Also $80k!

    I saw that Seven Marine was shutting down after being acquired by Volvo!

    It only turns from the lower unit. The powerhead doesn't move. And twin counter rotating props. Very interesting motor. Reportedly $77K. You could get a basic Prostar for the price of that outboard!

    Good grief. My dad put the biggest outboard he could buy on a 18 foot Glastron in 1977, a 175HP Mercury Black Max. That motor was amazing. The ski wake - not so much. Wide, low and hard as a rock.

    We put a 140 hp 'Rude on a 13.5 ft Switzer rated for 115. She flew.

    Yeah...that would sink a Flightcraft.

    Super expensive...yikes.

    Cool rotating lower unit.

    Two speed transmission as well.

    Might make sense for an outboard surf boat. Overkill for skiing unless you were going for a 100 barefooters behind one boat. Hang 3 of those on the back of a Dyna-ski?
  • chrislandychrislandy Posts: 188 Solid Baller
    Surfing that close to the prop?..... sorry, my mistake... carry on

    Rope pylon will need to be 12 to 15" taller to clear the motor. Not to mention the wake. The weight alone will rip the transom off the back of the boat.

    Show ski teams already put three big outboards on their rigs.


  • ReallyGottaSkiReallyGottaSki Posts: 218 Baller
    yes, the 600 is reported to weigh #1260


    Consider new in box GenV LT5 Crate Engine – 755HP is like 19k plus some grands more for an ecm and harness
  • VONMANVONMAN Posts: 235 Crazy Baller
    Holy Mother of Acceleration! That rig has got to weight over 1400 lbs in motors alone!

    @chrislandy I am surprised no one has built an outboard surf boat with an extended platform. Make a larger platform to make an engine well for the outboard and use one of those power brackets with a limited trim and voile.

    @BraceMaker I'm not, my understanding is that an outboard prop is limited in size and thus water displacement at low RPM is therefore it's inefficient i.e. low speed + high load = large diameter + low pitch

    hence why when dock starting with an inboard, you can start with no or one loop and an outboard needs 2 or more loops
  • skiinxsskiinxs Posts: 627 ★★★Triple Panda Award Recipient ★★★
    @chrislandy I'm not following your "outboard prop is limited in size" statement. Large outboards can accommodate up to 16" diameter props and pitches up to 36". A 450hp 6.2Nautique standard prop is a 12.5" (diameter) x 15.5" (pitch). Seems to me the opposite of what you said.
  • BraceMakerBraceMaker Posts: 4,569 Mega Baller
    They can be just about anything you want them to be these days.

    If you had to take all recreational boats sold today and pick only one type of drive configuration I think outboard would be the clear winner as there are certainly a lot of disadvantages to inboards be it DD or VD outside of a very narrow margin.

    More so I think that what you are seeing is that waterskiing and boat engines had somewhat different development paths where it was clearly an advantage to have a large 4 stroke engine making 150+ HP when the merc 60 ho outboards were new.
  • chrislandychrislandy Posts: 188 Solid Baller
    @skiinxs I've only seen small props on outboards, so I stand corrected on that point.

    BUT, I've also never seen a smallish, slow, semi planing hulled boat that needs a lot of low speed power to use an outboard. Everything I've seen is inboard - but again, that's only what I've seen.

    How about this?

    Take out the powerhead and put it in an inboard.

    That prop made by Dyson?
    slow
  • BraceMakerBraceMaker Posts: 4,569 Mega Baller
    @chrislandy I'll put it another way. Surf boats uniquely are well suited for a V-Drive inboard configuration including for safety however they are also limited by that drive format when it comes to spending the rest of the day on the water.

    That prop is cool but sharrow quoted me 6 grand for one for an inboard.
  • chrislandychrislandy Posts: 188 Solid Baller
    @BraceMaker you could say that about any of our types of boat though
  • BraceMakerBraceMaker Posts: 4,569 Mega Baller
    @chrislandy right I'm just saying as outboards have gotten bigger during the "tritoon" craze of the past say 8 years there are now powerplants that could power an outboard boat that you could surf if it had a platform that extended beyond the prop - said platform could also be a ballast tank.

    Imagine a tritoon with an engine well behind the toons but the outer 2 toons extend rearwards and support a tank/platform with wakeshapers. I don't surf but IMO that's a better product than a large V-drive boat - would hold 30 people in my state where pontoons really don't have capacity labels.

    To just goes to your comment of surfing near a prop is all - I think the engines are there such that you can now have an outboard surf boat - I think all around it could be more capable than many V-drive surf boats. And if the only risk is prop injury an extended platform would solve for that.

    Similarly and to avoid too much surf commentary which will get this thread buried to avoid google optimized hits - such an external/expanded platform would solve my big gripe with outboard ski boats which is getting a ski on while balancing on a 2x2 platform with an engine poking out and a handrail to sit on.

    Volvo and MerCruiser make I/O “forward drive” lower units for boats marketed to wave sports. I suppose someone is already thinking about outboard application.
