    Prop suggestions for 2003 Triton 190FS with Yamaha 200 HPDI?

    Hello,

    I have recently purchased a 2003 Triton 190FS with a 200HP Yamaha HPDI. In my test drive earlier this week with no gear, light load of gas and myself and another guy in the boat I was able to top out at 59.6 MPH GPS at around 5300RPMs. The boat does NOT have a jackplate and was running a 23 pitch 3 blade stainless prop. I had the throttle wide open and it trimmed up as far as it would let me go. The boat jumped out of the hole really fast, but I was hoping to get her to around 62-63mph...

    So asking the experts out there if going to something like a 24 pitch 4 blade or maybe even a 25 pitch 3 blade would get me up to that speed? I would consider adding a jackplate also if it would make a significant difference, but not sure if it would? Wondering if a 24 or 25 pitch prop would be a better place to start, not wanting to spend the $$ on a jackplate since I just bought the boat?

    My recreational use on this boat will be more pulling kids on tubes far more than pulling skiiers. So at this point I'd sacrifice a bit of holeshot for a little more top end speed. I also realize this is a fish and ski and I'm probably not going to get much more out of it than low 60's, but was somewhat disappointed that I couldn't get it over 60mph in the test drive.

    Any setup suggestions or any other suggestions for that matter are welcomed and very much appreciated!

    Thanks!
    Jeff

    Jeff,

    Welcome to bbcboards.

    If you want more speed you definitely want to stick with a 3 blade as 4 blades are typically a few MPH slower due to having to drag a extra blade through the water. You also don't need more pitch as your not reaching your max WOT RPMs (5500 for the HPDI) with your current prop, add more pitch your boat is going to be slower up top and sluggish everywhere else due to your motor not having the power to turn it.

    I would recommend as 23P Tempest Plus. It has the bow lift your F&S will need to go faster and carries heavy loads really well. Your also going to want to add a jack plate to get it dialed in. A 6" manual will work nicely. I would expect you to pickup a few MPH with the combo.

    Jeff, Is that motor the 3.3L Vmax? If so, talk to the hydrotec guys on the Yamaha high performance board. The 200hp 3.3L block was only set to so it would reach 6 or 9 degrees timing at WOT (cant remember which one it was.) It is a simple swap of the ecu and throttle cam to turn it into a 225hp. Those two parts are the only differences between the two motors. Did it myself and it was a fast, relatively cheap way to pick up 5mph on my setup. The swap itself took maybe 20 minutes to do.
    You also never said what exact prop you are currently running? I agree with dan02gt on the tempest plus, just not positive on what pitch. If you can check out and say what model stainless 3 blade you are running, that would say quite a bit. Good luck and congrats on the new boat!

    Jeff, I just ran your numbers through my trusty prop slip calculator and came up with 7.98% prop slip. That's to good to be true especially for a fish and ski, 10% is doing good. That makes me suspect your tack is reading a little low and your really turning ~5450RPMs at WOT. That's really close to your max WOT RPMs. This is a good thing. It means with raising your motor a little with a jack plate you should be able to turn a little more prop than a 23P. A 24 may actually be your best bet, but you may want to have your tach checked first.

    Add the mods astrofx was talking about and you may be able to turn a 25P which would put you around 64MPH.

    Thank you for the replies dan02gt and astrofsx, the information is much appreciated! I think I'll start with the 23p Tempest Plus per your recommendation. During my test drive it had an unmarked, generic looking prop on it. The only markings I could see just said "23". I know the Tempest props have the word etched or molded into them, and this one clearly did not. So I really don't know what kind of prop it was beyond being a 23P stainless, 3 blade.

    Honestly, I really didn't pay very close attention to the tack during the test drive. I know it was around 5,300 to 5,400 RPM's at WOT. So if the max on the motor is 5,500, then I was close, probably close enough.

    I also don't know if it's the 3.3L motor or not. Thinking it's not. Did they make the 3.3L in 2003? I'll check and find out and if so, thanks for the suggestions to turn it into a 225!

    To start with I'll put the 23 Tempest Plus on it and see what that does. From there I'll look at a jackplate and then maybe see if it will handle a 24P.

    Again, many thanks for the suggestions guys!!
    Jeff.

    Sounds like a plan to me. A prop shop can re-pitch a prop 1" either way so if need be you could have the 23 turned to a 24 for significantly cheaper than buying a new one.

    Good luck and post your results! They did make the 3.3L in 2003. You can check for sure by posting your model number on the Yamaha performance board and just asking what can be done. They will be able to tell you what you have and are very helpful about offering info on what can be done and prices. They spent a bit of time with me on the phone explaining things before I did anything and that helped a ton. Don't forget to put some pics up of the new ride!

    What they said! The 23 Tempest and a 6in manual plate should get you where you wanna be. There are a couple 6in plates for sale over in the jackplate section. If you are leery about the plate, like I was, I can tell I picked up 4 mph when I added mine and another 2 when I had the prop worked. Boat road and drove way better too. Good luck.

    Thanks for the info!!

    dan02gt, thanks for the prop shop suggestion, will check that out when the time comes!! Thanks again for your suggestions!

    astrofsx, good to know on the 3.3L. I take delivery of the new boat this Thursday and will find out more then. If it is in fact a 3.3L I will definitely look into that! Thanks for the suggestion on the Yamaha board post on that. Here's the only pic I have of her so far! (attached)

    Gunny146, Thanks for the confirmation on the setup recommendations!

    Thanks for all the good wishes on the purchase guys! The motor has 339 hours on it, so hoping it has a lot of life left!

    Jeff.

    Hey guys, I picked up the boat last Thursday and fished a local club tournament out of it on Saturday. Got some interesting info to share with you on it and hoping to get your opinions on this...

    First, the motor is a 2002, it's the 2.6 L HPDI. So no luck on the 3.3L suggestion to take it up to a 225HP.

    OK, so I now have all my gear in the boat, most of which is in the front compartments. Tackle boxes fill up the port side, about a dozen rods in the center rod locker and the rest of my random stuff in the starbord side. I had at the time prob 3/4 of a tank of gas and a full livewell. I was the only person in the boat. I asked for a 23p Tempest per dan02gt's suggestion but the dealer didn't have one in stock. It has a Yamaha (I think) prop on it, the markings on the hub are "23-M", 3 blade stainless. I put my foot in it for a bit running uplake in the afternoon and was able to hit 5,900 - 6,000 RPM and 61 MPH on the GPS... ???? I didn't really stay there long as being over 5,500 RPM made me nervous...but I think I could have gotten more out of it if I'd stayed on it, but being near 6,000 RPM I thought I better not push it. Per my earlier post, during my test drive with me and the salesman in the boat and no gear, and not more than 1/4 tank of gas I was only able to get this boat to around 5,400 RPM and 59.6MPH GPS.... So what the heck changed?? I think this is the same prop that was on it during my test drive. There are only 2 things I can think of to explain the change...but hoping you experts out there might confirm or know more?

    1) With the extra weight in the back with the gas and full livewell it allowed more bow lift so I was able to get the nose up more giving me more RPM's and speed??
    2) The dealer put some kind of rev limiter or governor on it for my test drive to keep someone like me from blowing the motor during a test drive, a limiter they have since removed??? Is there even such a thing???

    What do you guys think?? This really surprised me. But it now makes me wonder if I should put a 24P on it to bring the RPMs down just a bit and to pick up some speed? Hole shot is less than 2 seconds (guessing, but it's really quick) to plane with the 23p prop. Thoughts?

    As always, any comments or suggestions are greatly appreciated!
    Thanks!
    Jeff.

    Hey Jeff, Good to hear back with some testing results. The absolute first thing that I would do if you aren't sure is go to this site and download the owners manual for your particular model.

    Owners Manuals | Yamaha Outboards

    Figure out what your max operating range is. If it is model VZ200A which says it's a 2002 2.6L V-Max HPDI, the max operating range says 4500-5500. I would be very hesitant to be running 5900-6000 if it is, and you should look for a prop to bring your RPM's down to the very top of that range. I know there will probably be some guys on here that will tell you they run to that rpm all of the time, but I would rather trust the manual rather than some guy on the internet (me included.) You know they can't put anything on the internet that isn't true! lol
    On the prop, a Yamaha "M" prop is actually a very good prop and similar to a Merc Tempest Plus, so it actually is a close comparison to what a 23 tempest plus would run. For every pitch you go up, in theory you bring the rpm's down about 200rpm. A 24p SHOULD run about 5700-5800, a 25p again SHOULD run about 5500-5600.
    On the speed difference. There could be a few reasons, or a combination of them. My boat loses about 1 to 2 mph with the addition of another person. Having as much weight as a person sitting so far forward as in a fish/ski hurts the prop's ability to lift the bow. Motor runs a bit faster in cooler weather than warmer weather, so just a temperature difference can be the reason. Or a simple answer is just some water in the hull. My setup will vary about 2mph just based on the above reasons, so I wouldn't look too far into it.
    Sorry for the long-winded post. Based on your numbers and ASSUMING that your max rpms are 5500, I would be looking to test out a 25p Tempest plus. Would mean your max rpms(in theory) would be around 5500-5600 running with one person in the boat in cooler weather. Should bring your rpms down a little from that with a partner or in the heat of summer. Again, it's not a perfect science, so all you can do is test one and then see how it runs. I would buy used ones off the prop board (that have not been worked,) test them, sell them for the same amount or a little less if it doesn't work out. You can test quite a few props and just be out the shipping for each one you try. Good luck and post back with what you decide to try and your results!

    Hey Steve! Thanks for the info, as always, much appreciated!

    Great suggestion on downloading the owners manual, I actually did that last week. It is the VZ200A and the max is 5,500 like you have said. I was concerned about exactly the same thing, didn't want to run it too high and blow it. So I talked to my guy at the dealership where I bought it. He is their salesman and head mechanic. When I mentioned the 5,500 RPM max he told me that his factory contacts at Yamaha said it was OK to run this motor up to 6,000 RPM, but not over that. The rev limiter on this motor shuts it down at 6,450 RPMs he said. He said his factory guy felt it was better to run these closer to 6,000 RPM's than lower... ??? So I'm not attempting here to say who's right and who's wrong as I am sure it's never a bad idea to go with the owners manual recommendations. But I also believe that sometimes big manufactureres who could be the target of lawsuits from time to time tend to err on the side of caution in their printed materials also. I also believe that insurance companies will pay claims based on those printed materials too..... So I'm just trying to absorb all this information and opinions and trying to get at the real truth and the reality of what the real range is here in order to get this thing set up appropriately....

    Since I just bought the boat the dealership is letting me try different props until I settle on one and will trade me when I decide. So I think I'm going to try a 24P next and see how I like that one. If it gets me into the 5,700-5,800 RPM range like you have stated above, that might just do nicely! Keep the RPMs below 6,000 and get me to maybe 62-63 MPH... I'd be pretty happy with that, especially without having a jackplate on this thing.

    I sincerely appreciate the info and the reply Steve!
    Thanks!
    Jeff.
