    Default Surface drive build kits

    Though it isn't technically a canoe, my kaboat seems to fit into the canoe forum a little better than the powerboat forum.
    Background:
    I bought a 1852 lowe with a 35 hp go-devil surface drive this summer and fell in love with the speed, and range of the bigger motor and the ability to run super shallow.
    I have a 7.5 2 stroke mercury and a 2.5 4 stroke suzuki for my kaboat, and the speed is nowhere near where I want it to be, though I was happy with the speed until I got a faster boat
    Anyways, this past weekend, I punched a hole in my aluminum skiff and ended my hunting trip on day one. I barely made it back to the boat launch area, and decided to continue hunting much more locally with the kaboat. I just couldn't access my scouted area at all, unless I wanted to drag the kaboat many miles up a creek, after spending five hours to get to the creek

    So, I have decided that I want to build a surface drive for my kaboat. I bought a 6.5 predator off Amazon for $126 plus $25 shipping. I still need to get the long tail kit.

    Has anyone here built one? If so, who did you build with? Am I being stupid? I know I won't get a lot of speed with a 6.5, but the big boat will be used to get out there, and the kaboat will be used to get just a little farther up the creek (since it will be much easier to drag than the flat bottom with the 35 hp).

    I am looking at either the short long tail kit from mudskipper (ebay) or their surface drive kit. But I know I have seen some of these smaller ones advertised on craigslist.

    A surface drive may have issues on the kaboat with the tubes going further back then the transom.

    The above is a 7hp longtail kit (looks like a SwampRunner kit) on a boat that is very similar to a Kaboat. He takes it up some pretty decent water and doesn't look like any issues hitting the tubes sticking out the rear. Might want to turn down the volume, he's got some strange music in the background

    That is the kit I would go with on a Kaboat. I have a 6.5 Kohler new in the box that I will be ordering a small SwampRunner kit for. I dont think a surface drive (short tail) would work as mentioned above.

    Surface drive accompanies all surface drive for me. I am actually looking at the short long tail twister from mud skipper.

    I have used both a swamprunner long tail and a twister on a 15 foot kaboat. You need more power. I too am thinking about a short tail surface drive but need at least 12 hp. You will be disappointed with less hp

    What sort of speeds did you get? my application is going to be after I set up camp as far up the creek as I want to go in my flat bottom with surface drive. But I know i could go further, but not wanting to drag the bigger boat. If that makes sense. I'm kind of double dipping in the surface drive/long tail area, but I know the kaboat has the lighter weight for dragging and much easier to row for floating aspect.

    I was going less that 10mph. With the 15 outboard I went much faster. I did not actually measure the speed. Looking at maybe a 12-14. Would like a short tail surface drive

    With my 7.5 2 stroke I'm not blasting away. Solo I get 17 mph which is moving but loaded it with one other guy and weekend camp we get between 8-12 mph.

    I would be ok with less than 10 for what I'm using it for. I thought about the 16 hp mudskipper set up, but the weight is around 130 lbs. I'm afraid that would be too much weight in the transom.

    And in other news...project is on hold. Received a cancellation notice from Amazon. I put every motor I found in my cart, then deleted the ones that wouldn't ship. Apparently the ones that would ship, won't. Ahhhh...the joys of Alaska.

    AIH sells 7 and 15 horse motors, you can ask them if they'd ship. Home Depot and Lowes in ANC may carry motors as well, but they don't in Fairbanks and it would take 6 months last I asked.

    Thanks. I'll try that. I do have a list of motors that the kit will
    work with.

    I just seen these surface drive kits from Mud Skipper. Im not sure they are built too tough but definitely a bargin, and could be easily broken down for fly outs. See assembly instructions.

    If you could get one of these motor up here it would be kick ass on that kit.

    Or you could squeeze some extra HP out of the AIH motor by using one of these kits. Last week AIH Eagle River had a 15hp in stock.

    I've run a 10 hp copperhead and a 23 hp copperhead on my old kaboat. The 10 hp was just about right, the 23 hp was overkill. The 10 hp powered kaboat is pictured on my copperhead website.

    Go devils like your's weigh almost 300 lbs with battery and oil. gotta watch for stern digging too deep. When I ran a big go devil on a john boat, the key, was to just get it on step, and no more, or something was bound to break

    Just because you have the speed, doesn't mean you need to use all of it. How come you just didn't repair your boat, and head back out?
