flyin! picking up my gp tomorrow and already ordered my maptuner from you guys!

[@GreenHulkGarage]

Thanks so much

[@Beastboy03]

Man that thing is sick 😍thx for the vids

[@jimwinn8064]

Awesome job on the videos! I pickup my 2021 GP1800R SVHO & 2021 Yamha EX. Thanks for the tips/videos, I plan on installing these parts myself.

[@GreenHulkGarage]

Thanks! these parts definitely turn the GP into a whole new animal

[@thomasdamiano8260]

Thanks for making these vids, I just ordered a last of the 21 run models from riva. Plan on ordering a stage 1+ kit from you.

[@GreenHulkGarage]

Thanks for the support!

[@LifeBeginsOnTheWater]

Like always Greg, great job. Some good content for everyone as well. That ski is flying bro. Now we just need to get y’all on the water for a few rides with us. Billy D

[@GreenHulkGarage]

Don"t hesitate to let me know when y'all go ride. I would be happy to tag along.

[@aceofspades6667]

For me this would be the sweet spot in price to performance ratio along with the amount of wrenching on the ski. I wouldn't want to go stage 2 and the stage 1+ is a nice upgrade over stage 1.

Picking up my GP next week, just ordered the Stage 1 kit from you guys as well! After these mods and fine tuning for top speed, can the speed limiter be set ~80MPH to avoid hitting the rev limiter?

[@johncunningham1183]

I have the only blue 21 gp1800r in Nova scotia . Why would you not use the Solas 13/20 impeller instead of re pitching, only asking because I don't know

[@Breakitjake]

Another great video. One thing and correct me if I'm wrong, but on yamaha 1.8 supercharger engines. The breather hose sucks air in. Unlike any other crankcase vent I have ever dealt with which would expell the oily fumes into the intake. Like you said.

[@GreenHulkGarage]

The breather hose is expelling crank case fumes into the intake tube! This is not good for engine performance which is why it is important to add the engine breather kit.

[@R1Kyle]

@@GreenHulkGarage Why is it not using a catch can, I know they do not pump oil like a seadoo but there must be some.

[@cpoggiolo68]

How about a link to repitch impellers vid. Currently running 14 FZR Ribbon delete and Torx Stage 1 8400 . What pitch do you recommend? Tia.

[@PTRRanger951]

I’m not finding the video you did on how to repitch. What’s the title of it?

[@R1Kyle]

Have there been any / many cases of these impellers failing prematurely?

[@bernardmcnamara]

What did you end up repitching the 13/18 impeller too?

[@evostigti]

Great video. Question: The stock filter isn’t that cotton too just like auto filter ? The marine filter looks like it’s gonna suck water in like a straw, better off running no filter from the supercharger...

[@GreenHulkGarage]

The stock filter is similar to an auto filter. The marine filter is better than running no filter at all, it will prevent any solid particles from entering the intake. The chances of it "sucking water like a straw" is slim to none because it is high in the engine bay. However if it gets wet, it will dry almost instantly. A filter using a paper or gauze element will get wet and stay wet for extended periods of time causing problems.

Did you have to do the Engine Cooling upgrade kit on this too? My Stage one plus kit came with everything you had just installed plus the Engine Cooling upgrade kit.

[@GreenHulkGarage]

No, I will do the Riva Pro Series cooling kit when I install the Riva intercooler and go stage 2 👍

[@henrythompson5624]

So if I go with the stage 1+ wit the 13/18 Impeller but don’t know how to Re-pitch the impeller that means I can’t ten the 88 tune because of rpm to high. If yes can I add on another bolt on part that will leave that out

[@GreenHulkGarage]

It depends on a few different things. Engine RPM varies depending on your location of the world and weather conditions. Higher altitudes will have lower RPMs and hotter temperatures will have lower RPMs. Repitching an impeller is surprisingly easy, I have a whole video on how to do it! Here is a link to that video: kzbin.info/www/bejne/opnTiYGEg52phMU

[@Vince-jj8qs]

Do you lose the software choices for driver assist. Auto Trim and Drive modes when you load the new tune???

[@GreenHulkGarage]

You do not

[@Charles-rn4li]

what kind of tuning do you think is available for a 1998 seadoo gtx? i feel its got a lot more to give im just not sure what direction to go....

[@GreenHulkGarage]

There’s no tuning or performance parts available for it unfortunately.

[@skipmidgett6189]

Any suggestions on how to get the pipe into the hull? Did you go thru the front? It looks like there isn't much room with the wires and big vent pipes. Thanks

[@GreenHulkGarage]

I go through the engine bay. I turn it upside down to get the front in first and twist it through

[@jasonmekush5280]

Today, I have a race mechanic , custom pitching my prop solas starting at 13/20, hitting 8050 rpm at the moment stage 1 plus + kit. 94 degree heat in fl. Having it repitched as a specific rpm target 8500, Ill let you guys know how it turned out even the cavitation level. Btw the solas 13/20 just roasted cavitation all the way to 20 mph, skii makes too much power

[@GreenHulkGarage]

Sweet! Do not pin the throttle from a dead stop. You have to modulate the throttle to limit the cavitation to get the best acceleration

[@jasonmekush5280]

@@GreenHulkGarage You will like the bottom end on ur hulk green gp when u do the intake manifold upgrade - aka ribbon delete. I used to race I J S B A expert class 785 runabout from 96--98 . I am pretty well versed with holeshot and cavitation mitigation. Keep up the great work on your vids, looking forward to your store offering new products for this machine.

[@bernardmcnamara]

🤔 cavitation of the start. Change the leading curvature edge of the impeller to a straight edge impeller thus improving the hole shot cutting down on the cavitation.

[@UHCohort2]

If I order this kit from you guys am I going to have to repitch the prop that comes in the kit or can we substitute the correct prop?

[@GreenHulkGarage]

The kit comes with the correct pitched impeller for the modifications and tune. Riding environments do vary so you can always optimize performance by fine tuning pitch for you riding area. More about this here greenhulk.net/forums/showthread.php?t=249244

[@warlordmel]

Exactly how much did you pitch the impeller? Did you do all the blades, and did you Pitch em up or down? Thanks for answers from Sweden! :)

[@GreenHulkGarage]

I pitched them 1.5mm (added pitch) You must always pitch all blades and make them identical.

[@warlordmel]

@@GreenHulkGarage Thanks 👍

[@markthompson5934]

What about engine cooling upgrade kit is it necessary to install or just helps out. Is the 1 plus kit in stock?

[@GreenHulkGarage]

It is not necessary, but it definitely helps and I do plan to install it. During the speed testing performance was lost due to heat fade. The 1 plus kit is currently not in stock but should be very soon.

[@David-dg3kb]

Do you prefer not to run the impeller boot on all skis or just specifically the gp? Just wondering if my Rxp would benefit from removing the boot.

[@GreenHulkGarage]

Don’t run them on any skis. They are problematic, they come unscrewed, walk up the shaft and cause cavitation issues.

[@AftrBurNr]

@@GreenHulkGarage That happened to me on my sea douche

What is the advantage of the 13/18 impeller vs the 13/20? The riva kit has a 13/20, what makes you choose the 13/18?

[@GreenHulkGarage]

No advantage, the 13/20 is the correct impeller for these mods, but it was on back order from Solas. So I pitched up my 13/18 to a 13/20

[@tuckerm8089]

@@GreenHulkGarage I have a 2021 GP1800 also with the same mods only a 13/20 solas and I am only seeing 75mph at about 7800rpm. Riva 8500rpm tune. With the stock impeller I saw 78mph at about 8000rpm. Full tank, 90 Air, 80 water temp. I have a Riva intercooler and cooling upgrade on the way to hopefully add a little more power and a ribbon delete kit. Im sure a 13/18 would get my speed up but my question is with the new parts on the way do you think I should order a 13/18? I don't plan on doing valve retainers so 8600rpm or less is where I'd like to be at. Also should I be running the 8800 stock class tune? Thanks for you advice and info!

[@rickperez428]

With this upgrade is it still under warranty compliance?

[@GreenHulkGarage]

The Stage 1 8000 rpm tune is not detectible by the dealer 👍

[@GreenHulkGarage]

Also, 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 👍

[@GreenHulkGarage]

@@costasgeorgiou5015 absolutely slow it down! The Skat is a good rough water impeller, but slower on top end than the Solas. You’re misinformed on the Solas impellers coming apart so let me enlighten you.... Most of the “Solas” impellers that come apart were Chinese knock off’s.... not real Solas impellers. These knockoffs even come in “Solas” boxes and look legit! Solas had a bad run of Sea Doo 300 13/18 impellers that were folding over and failing. Panic spread throughout the internet making everyone think that all Solas impellers were bad and would blow apart. Not the case!! Solas corrected this issue with the new SXX series 13/18. Yes, there have been some failures of real Solas impellers fail for other model skis, but Solas stands behind their product and if there was a failure they replaced the impeller. Solas offers the best and fastest impellers for our skis, I run them on my skis and never had an issue. If you are in the market for a Solas impeller be sure to buy from a reputable vendor that sells genuine Solas impellers. The GreenHulkStore.com, Riva and Impros all sell genuine Solas products 👍

[@GreenHulkGarage]

@@costasgeorgiou5015 and FYI, I have been using genuine Solas impellers for nearly two decades on extremely highly modified skis and have not had any Solas impellers come apart on me, not a single one! I also sell Skat Trak impellers and use them on some of my builds and I have had two of them come apart on me, but this was on a very high power 100 mph turbo FZR build. You can check out any of my builds on my forum GreenHulk.net

@@GreenHulkGarage not goin lie a lot to read brother. But Solas is still having issues and I won't go back. Glad you got luck with them I don't and mine were also legit props. I have 2 skis well over 100mph (108 to be exact on GPS) and the quality of the skat its unrivaled in my book. I know your greenhulk mainstream thing but us fast back woods boys go with skat to be fast. Let me make clear not knocking what you do by no means I just don't do "mainstream" out yonder. But let me ask you this I'd you can get polished or brushed in skat or Solas and have the same pitch (true pitch with skat) what would be the dif in the same ski for speed. All my skats aren't off the shelf there made to my specs when I call them.
