    Default Outboard to jet conversion?

    So Im thinkin of converting a 21' Daytona, it was a wacker, and I want a jet... How hard or complicated is setting a intake? Is it something Im best letting the pros do? what would something like that cost to have done? any suggestions would be great, its a rounded keel also...

    I was going to do the same thing to an open 21 bow Kachina and from what I found out it's pretty easy to do. I was going to have somebody else set the intake though.

    My 21' rolled out of the factory as an IO, the guy I bought it from was atempting to hang a wacker on it. Now it's a jet. I had Tom at JBP cut and set the intake. If I can help or shoot you any pics or measures let me know.

    My 21 was an I/O previously, now a set back Dominator pump, so it must be pretty common. My transom is about 3 inches thick
    Love the boat as a jet and wouldn't have it any other way.

    Yup... Im the one... It was listed a hour when I called... I had to pay more, the price was up a grand from his asking when I called, and he said he was offered $4K to hold it... But I was first there with hund'ys in hand... Im still not sure Im gonna do it, but since I have a engine, Im thinkin it couldnt be too costly to jet it, or so I hope...

    I'll be the one that says...DON'T DO IT!
    Why give up a lot of interior room, make you boat heaver in the ass and, unless your talking a LOT of V8 HP >sloooower.

    I've seen a few 21' tunnels with a wacker on the back simply float ontop of the water(effortlessly) while I was still plowing and making a lot of noise > and we were just crusing.

    Cutting the hole, setting the intake isn't all that difficult...HOWEVER...measure several times, cut once

    PS I didn't purchase my 21 Daytona because it was a "Jet" (if) it had a wacker on the back I still would have bought it > > > just faster lol
