I had an old 2003 gp1300r stock was about 65mph I put a lot of money in it from a upgraded water box to a new ride plate and intake grate and new prop and it gained maybe a mph or two but I raced a new gp1800 even thought it I’d bigger it was quicker and had a higher top speed of 70 I was impressed with the stock performance and even with just the speed limiter removed it gained another 5mph I think 75 is plenty fast for someone who doesn’t do it for a sport just to have fun on the weekend 75 is plenty.

Just got our 13/18 and intake in yesterday, will have results for that soon. Your local dealer should be able to get the 160mm transom plate taken care of for you
What pitch would you say you pitched it to? 13/18? 13/20? Very impressed with those pitching skills btw. I have a 2021 GP1800R on order and already have a box of parts in the basement waiting!
Hey there, how do you gain on both, top end speed and acceleration with a re-pitch of the impeller, don’t you always gain on one and lose on the other?
A general rule of thumb is that higher RPMs bring higher top speed. Re-pitching the impeller to get higher RPMs will allow the engine to spin faster more easily which brings harder acceleration. Top speed and acceleration will typically increase or decrease together, not one or the other.
@@GreenHulkGarage I’m sorry but that is wrong. It’s true, re-pitching will increase or decrease RPMs but whenever you re-pitch you will either get better top speed or better hole shot, not both. When one improves, the other suffers. www.impellers.com/impellers-101.html
Getting your information from a company that has a bad reputation and is known for selling knockoff impellers is not the wisest thing to do. We’ve been in business for over 15 years and have an excellent reputation behind us. Every watercraft has a set rev-limiter, depending on the tune you are running it will vary. I typically pitch my impellers to run 150-200 RPMs less than the rev-limiter to avoid hitting the rev-limiter. In this case that meant re-pitching my impeller to reach a peak RPM of 8500. If I were to run 8000 RPMs instead my engine would be working harder and not be able to accelerate as fast. Less RPMs also mean less pump pressure creating less thrust. This was proven in a previous video when I had a slower top speed and acceleration when turning 8000 RPMs. impellers.com’s analogy to a motorcycle transmission does not apply to personal watercraft in any way shape or form. The information on their website is simply incorrect. Any time RPMs are increased, you will gain acceleration and potential top speed. Jet pump impellers cannot be compared to motorcycle transmissions or boat propellers where the logic of gaining top speed but losing bottom end acceleration holds true.
@@ShutterMAX In a straight gearing relationship on a normally aspirated engine, your statement would most likely be true. On these SC engines, you decrease the pitch for bottom end and the increase in RPM creates more boost and allows the engine to run a higher RPM overcoming the lower gearing. You do in fact get more acceleration and higher speed.
I watched video you posted on the mods you guys did on 2017 gpr and the guy in video said ski runs faster without the billet nose cone thst came with the 13/18 solas impeller????? I ordered the 13/18 just wondering if you still did not install with 2021 gp

@@GreenHulkGarage how difficult will it be to modify my 13/18 I’m thinking I should have just ordered the 13/20 I’m afraid of running too many rpm and hitting limiter ??
I really don’t have a favorite. I ride them both and enjoy them equally. watch my comparison video between the two where i go over pros and cons of both the Yamaha and Seadoo!
It is definitely a fun ski. I can’t say if it will do a 180 or a 360 because that is just not my riding style and I have never tried. The intake grate design does keep it hooked up to the water extremely well.
I have a 300 RXT and it pretty hard to do on that ski. I enjoy riding as well but like to cut up and have some fun. Maybe your next ride you could give it a try? Your feedback would be appreciated. Enjoy your video as well. Thanks
I know this is a a Yamaha video. But I put a SCOM, intake, free flow and catch can and I’m only running 75. I only have 5.5 hours on it. Does it not completely unlock until 10 or am I just slow
That is the correct speed. You may notice a slight gain once the engine is fully broken in, but it is no longer limited by the computer. The SCOM isn’t a tune, it just removes the speed limiter. To notice a significant increase in acceleration and top speed you would have to tune it. With a tune you can take more advantage of the air intake and get close to 80 mph if not over 80 mph. I personally use the MaptunerX tunes and have outstanding results with them. www.4-tecperformance.com/index.php?main_page=product_info&cPath=316&products_id=4243
They cannot “void” your entire skis warranty for doing a mod to your ski. They can “deny coverage” on a failed item if the modification is proven to have caused the failure, but your entire skis warranty is not VOID!! For example, let’s say you reflash your ecu with a performance tune. If your steering breaks, instrument cluster goes bad, a sensor goes bad, etc, then the reflash could not have caused one of those items to fail so they cannot deny coverage. Now, if you have some sort of engine failure then they could absolutely deny coverage on the motor repair. Point i’m trying to make, is your entire skis warranty is not VOID if you mod your ski. Research Magnusson Moss Warranty Act. It protects us consumers when modding our skis 👍
I would love to help you out but can you further elaborate on your question? On a jet drive there is a pump that sucks water through an inlet, pressurizes the water flow, and pushes it out of the back of the ski to create propulsion.
If you guys wanna make some real money contract with a marine upholstery place and sell a rear seat cover . that warning sticker is the stupidest thing yamahammer ever made. Ill put an order for a blue n white one.
Yep, exactly...it cost me $10,000 twelve years ago to get those numbers on my FZR.

Does Maptuner Bundle include the Yamaha license or is that extra?
It includes the tuning license
Is that license per ski or does the Maptuner do multiple skis? Just got the same identical ski as your 2021 GP1800R, same colour and all.
The license is per ski. You can use the Maptuner to tune multiple skis, you will just have to buy an additional license for each ski
Could u go more in depth as to why not to tweak leading edge?
Because pitching the trailing edge has more of an impact on dialing in your top RPM.
@@GreenHulkGarage is there a situation where you would adjust leading edge?
Thanks, I gotta adjust my prop. Only turning 8150 to 8200.
