    So you ran the T500 motor, but which Kv specifically? You mean T600 also fits?
    135* is good!

    No I have not run any of them yet, I see what stock does first.
    And then I see what I can mod to make it work better and handle better.
    Then more motor may be.
    And the t600 is a monster, That my go in my 36" shockwave.

    Ok up date, Water was 45f and ran on a 3s1p 30c 4500mah pack and got 8 minutes run GPS AT 28 MPH.
    All temps were good and temp at the motor mount clamp was 115 f getting better.
    So if modded with a water cooled mount it should be a really cool running setup.

    That sounds great! The temp is really good now, 115 at motor mount clamp is nothing!

    Joe, did you look at post #31? Lenny posted them when he made the mod a month ago.

    Yes, I gave him links to hear when he first got the P1 hull on 3/22/12 to make it easy for him,

    I do not think he sees or reads to well.

    Lenny I did not look though all the links, sorry did so tonite. I like how your boat handles with the off set rudder. I will be putting my boat together soon waiting on a stock out drive to get here. I am going to add some fiberglass to strengthen the hull. I bought some turn fins off of ebay.

    Hi Lenny, how is everything? I got so hopelessly side tracked with my Pursuit which has a stubborn water problem coming up the stuffing tube. I am just about to give up today since I tried every imaginary ways, it's jinxed like there is a pump sucking water up. I miss my P1!

    It could be better, But it could be worse.
    The Pursuit you have, Was that Blackjacks ?
    Love my p1, But still need to work on a stronger hatch and better seal for it.

    Yes, I got it from him, at first it was running bone dry, no problem after I put a silicone fuel tube, but then I needed to use Kintec flex cable, and the problem started. It has a 2.25 inch shaft, standard I was told, since the boat has a stinger. Original shaft was shorter and was told it was an AQ product. Had to change since it was no longer holding up. Anyway, I put all kinds of tubing to seal it but water still comes in. The boat runs well, I used m545 prop and I get 47mph. Leo 4082, 2200 Kv, Seaking 180 a ESC, 4s2p . Temp is all good. I suppose I could run the boat a bit drier still, but now it is very stable and doesn't mind chops. I guess it was a good learning experience as I learned to adjust tirm tabs and stinger angles. I am reluctant to post anything because it is so silly.
    P1 is really a pleasure, will run again when time permits.

    Hi Lenny I am getting ready to mount my turn fins on my Kos, how much of an angle do I need of them and how much of the fin goes into the water? The fins are 67mm in length. I bought the carbon fiber one's. Also I just bought the speedmaster stinger from Steve I will be getting it next week. I should have neve bought the stock stinger for it. But you learn by your mistakes ( I think).

    You want the turn fin angle to match the hull bottom at the transom,
    And ideally have it touch the water only in a turn for less drag in the straights.
    Hears some pictures of mine.

    Ok,
    I have done some more testing,
    With the modding of the inside setup,
    The boat is very stable in the chop at high and low speeds.
    Also I move the timing to 26.25*and temps went down and speed went up.
    On a 3s I was getting 28 to 30mph, Now on same pack 35mph.
    Not sure if run times are any better yet,
    I will be testing 4s again and see what run time and speeds are next.

    Lenny, I forgot, are you still running with the stock out-runner? If so this is great, I also had temp issue, guess we talked about it. Eagerly wating for your 4s results.
    Cheers!

    Yes, Still stock motor.
    And I got to run it in the big lake yesterday,
    With a 1970 jet bout with a 454 big block for lot of chop and some tubing and knee boarding,
    First time for me on a knee boarding and had a blast.

    More money for more boat and stuff,
    Yes, But I am feeling it to day.
    When I got to the lake it was almost glass for 1/2 hour,
    Then the jet boat rolled in and one jet ski and some hooter, Now were having fun.

    2012-06-10_23-43-19_258_edited-1-1.jpgLenny here is a picture of my boat. I just made the extension block of my rudder arm to extend the rudder back because of the longer stinger. The extension I made out of wood. Will show a picture of it mounted in the next couple of days. I am painting and clear coating it. Sent my props out fo sharpening and balancing to dasboata a member here on OSE.

    I would not use the extension,
    If you leave the rudder closer to the transom it will be out of the prop thrust cone.
    And give more speed and more control of turns,
    Plus If it back to far you have more torque on the transom bolts and hardware.
    That could rip the transom out, Witch would not be good.
    Look at it as a breaker bar for lug nut,
    The longer the bar the more torque you have to break the nut loose.

    The one you saw in past post did not work good,
    But look cool.
    That was Member Jesse J P1 kos mod.

    I talked to him about that mod later.
