    K series hondas have sooo much potential. Even the vanilla 24a is good for something like 350hp without touching the head, even though everyone gets excited over the k20a(r). And there are fucking shitloads around, so not a major major if you kill a standard one (24, I'd cry if I killed a 20r hahaha). In an application like a boat, even better: more availability of bits that will work ex usa, and the yanks go mad for them. Not that it's a problem basing on a standard factory motor: Drown it, rev bash it, whatever.... So long as every second Auckland housewife has a crv/accord and can't drive for shit, there will be loads of spare engines available

    True in some points the k24a has a few negatives over the a2 if you are going to boost.What i have found in my real world testing is standard motors with boost dont last.I think all these claims on the net of 500hp on a s/h block straight out of a car may work in the short term but not for long.I think drag racing and jet boats place different demands on the motor for longer.Hopefully I wont need a spare motor after building this one for a very long time

    Went for a blast in a mini boat in the weekend. Bunch of guys in a few boats went out for a play up the Waimak.
    4 minis with ski motors/pumps and 1 4.6 with a big V8. Couple of the minis had the supercharged Kawasaki ultra motors with a few mods. 1 was over 350hp.Sounded amazing.
    The boat I went in was a 3.8 Hydro with a Kawasaki 15F. Even with 4 of us in, it went well.
    I'd love to give 1 of these minis a crack. Maybe use a Honda k series motor though with a Scott unit

    I saw some pix of that, a mate who was on the trip sent them to me. He had the Jetech with the supercharged Kawi in it.
