    Default right prop???

    Need a little advice on a prop. Running a Bravo one 48-831914 26P 4 blade stainless prop on a bravo one outdrive powered by a Raylar 525. All this awesomeness is in a 28 foot Nordic Heat. I normally run on Lake Coeur' Dalene in Idaho, at an elevation of 2125. I can usually run about 64 to 66 mph, at 5300 RPM sometimes a little better in rougher water since i have a step hull. Wondering if this is the right prop or not. I can get out of the hole pretty quick, but wondering if i can get some more top end with a different prop, or if i need to go back to my Bravo XR outdrive with a 1.51 to 1 gear ratio. Any help would be appreciated.

    Too bad you're not closer, I have a 22P B-1 as my spare / big load prop. You would be welcome to try it.

    Do you know what they set your rev-limiter at? Stock HO was 5150. Obviously it's higher, since you are occasionally hitting 5300. I would see 5500 being fine for your motor. A 24P would put you right there. Standard loss is 3%hp per 1000 feet. Any warm day at all, you can figure your density altitude is at least 3000 feet. So, you're down 10% on HP on any given day. I think a 24P would be fine for you, but if you try a 22 and decide that's the prop for you, I would be interested in trading you my perfect 22P for your 26P (in similar shape). I am ready for a 26P but don't want to get rid of my 24P.

    If you're still running a 40wt oil in the motor and 90w in the drive, you are losing some more there, especially as cool as it is there. It's not like it gets to 110+ ambient there like the rest of us boat in. Plus, you have superior cooling with engine oil cooler and closed engine cooler. So, you can run a good synthetic anything-30w and a thinner synthetic drive lube. I would actually try this first, if you haven't already, as you will pick up a bit of speed. Every boat is different, but I picked up a solid 3-4 mph on the top end.

    I run Mobil-1 10/30 in the motor and TORCO RTF in the drive. The RTF is a ~30wt gear lube that treats parts BETTER than a 75/90 gear lube. So, you can treat your outdrive better AND free up some lost HP. AMSOIL makes another good lube that is specific for drives as well. RedLine probably does as well.

    Which exhaust did you end up with after the Raylar package?

    First of all we need to know if you currently have a 1.5:1 g.r.<br>
    If you do have that gear ratio, your slip % is over 23%. This is unexceptable and would prompt other questions. Your current propeller would be out of wack and correcting that would be the first step.<br>
    <br>
    We have a test propeller program that could help you. Let us know any other questions you may have.<br>

    Welcome to the boards. I have a nordic as well and have found that the p5x works the best for me. BBlades has had there hands on it and did a very nice job with it. I have found that my boat works the best all around with the 5 blade. I do run a little more power that you but you should give BBlades a call and let them work with you to get you to where you want to go. Remember you normally can't have the best of all worlds you usually have to give up top speed for hole shot or a fast cruise speed for top speed ...... You get the point. I have just had the best luck with my p5x and my setup to get good hole shot, nice cruise, and still the fastest top speed out of my boat. Do you know your x dimension of you boat? And do you run any drive spacers? Things to think about. If there is any thing that I could do to help pm me and I try to point you in the right direction. I have had 3 different power plants in my boat and all of them had a different setups to run there best. I have learned a few things about the Heats over the last 5+ years. Get a hold of me I would love to talk.

    Thanks. Brayden

    Brayden, i actually looked at your boat when i was looking at purchasing my Nordic! Saw it on powerboatlistings i think and one other. i do have a 1" drive spacer and an XR lower. I had my upper drive replaced after i got the boat and the cone clutches seized once i let my wife drive it, long story (lesson learned!!). H and S marine is spokane worked on it and said i had different gears in my upper than normal. I see that you can get 1:36 to 1 gears instead of the Bravo One XR gears. I ran 73 on lake mead with that set up, but had to replace and cant get my speed back. might try gears and bravo XR upper and lowers. I will give BBlades a call. i spoke to precision propellor in spokane and they said i am right on with that prop, but i figured i could try some other things. I will pm you as well. Did you ever sell your boat and buy a cat like you were thinking? Thanks man! Counting the days to summer!!

    NO, YOU DON'T WANT GEARS. You actually need to confirm that you have 1.50 gears NOW. If you have 1.36, you want 1.50s.

    IF you have 1.36s, you could try a 22P, but I don't think that would be enough reduction in prop to get your R's where you want them. Hard to tell without being in the boat. These prop guys should be able to get you dialed.

    No gears? ...ok well i will confirm, but the bravo one i have on is factory, so i am guessing that they haven't been swapped. I have all the receipts from the previous owner, and he had a bunch of work done at Absolute speed and marine in Havasu. I called them and they are looking into what they exactly did. It had a Max Machine Worx Drive upgrade, and i dont know what that consists of. It sounds like i just need to try a few different props. Would anyone recommend going back to the bravo one XR for any reason? The motor was supposed to put out 525 hp, but the bravo one should handle that. It also has a 1" IMCO drive spacer. Should this come off? I don't know too much about this so i am learning as much as i can!!

    Well, 1.36 is a HIGHER gear than 1.50. Peeps change to 1.36 gears when they run out of prop on 1.50 gears. Say you hit the wall with 1.50s and a 34 or 36P prop. Spinning that to 6000 rpm would make a person switch to 1.36 gears and go back to / say / a 28P and start going up in prop again until they get their RPM stabilized. So, you want 1.50s at this point.

    I would still be looking at the simple stuff first - is your throttle cable opening the TB all the way?

    I still have my boat, and prolly have it awhile longer due to the fact that I do not want to move on the price to much. I would really like to have a cat someday but just need to find the right buyer for mine first. I hope that you are having fun with your nordic and if there is anything that I can do to help with things let me know. It would be fun to get them side by side this next summer and run down the lake.

    We still need to find out what gear ratio you have. This is first on the list.
    Second, I don't think at this point that removing the spacer is a good idea but, we can look into that further as we move along.
    We may need to look at your prop too, to see if it has had work done to it.

    Ok! BBlades, finally got a chance to look at my boat and gear ratio. I am running a bravo one upper and a bravo XR lower. The upper outdrive has a 1:50 to 1 gear ration. The bravo XR outdrive i had to pull off had a 1:36 to 1 ratio i believe. I am no expert, so i am wondering if this is where i lost 5 mph or so in my top end. My hole shot is great, but if i can switch back and get more top end thats what i am looking for. With the trim tabs and trim all the way down, i got out of the water just fine with the XR. i usually dont let a lot of people on my boat, so no need for an awesome hole shot. The prop has had no work done. i spoke with the previous owner and it is just a 26P four blade stainless. Thats the prop he always ran, although he ran on lake mead and i run on lake Coeur D' Alene ID. with 525 hp, i should be able to push more than 62mph at this elevation!!
