How To Adjust Jet Ski Impeller Pitch (on a 2005 GTX 185 Sea-Doo)

[@mjhmech4903]

After watching a few vids from RedRockat &3ft deep I removed the pump housing on my 08 215 RXP. The original impeller looked like it had sucked a bag of 6" roofing nails thru it at full throttle!! Mess does not come close to describing the carnage of the wear ring , impeller and pump casing vanes!! (How it performed as well as it did albeit lots of cavitation is a mystery!) Any hoo after a replacement wear ring (ref 3ft vids) this one (in my case to restore leading/trailing pitch) plus a few hours re profiling the bent and damaged leading edges on the impeller - hey presto it's like a totally different PWC!! Much better acceleration and top speed , no horrible noise when flushing (refer impeller bearing replacement vids) and a very happy albeit tired me!! Thanks guys - keep up the good work. PS and yes I have ordered a Solas replacement but for now the recond original is much much better than how it was!

[@nike12000haha]

Seems like bending that by hand without a dial indicator or something seems like you could end up with a vibration, no? I realize it's more money but isn't the best way to get a new impeller?

[@3ftDeepChannel]

nike12000 Actually, for the cost of shipping and about $80 bucks, Impros will adjust the pitch and make it like new. We didn't have the 4+ weeks to wait for the turnaround, and besides it's a lot more fun when you're screwing around with things you shouldn't be. At the end of the day it did make a difference (1 or 2 mph), and no extra vibration detected. Thanks for your comment.

[@AWDn0t2]

Excellent video, by the way! Keep up the great work!

[@bobhenderson7961]

My concern with this method is bending the blades will increase the gap between the impeller and wear ring

[@3ftDeepChannel]

Yes, but only a tiny bit. Thanks for your comment.

[@nanakofiaddo8478]

I have the 14/19 on a seadoo 215 with x charger and 42 injectors... runs great but I always hit the rev limit and it’s like advanced cavitation any advice..? I already pitched the pros

[@3ftDeepChannel]

Cavitation could be wear ring or carbon seal related, if hitting the rev limiter at full throttle. Check those, especially the wear ring. The impeller may also need more pitch to pull the rpms down and give more thrust, but more likely one of the other two possible issues. Good luck!

[@jeffreyverheij6745]

I am building a alu mini jet boat with 155 hp seadoo engine. The problem i am having is that it hits rev limiter, like you shown in the change the angle it you change the amount of rpm. But how does diameter and blade angle corolate to pitch number? Great videos it helped me a lot rebuilding the engine :))

Would love to know exactly wat lead vrs trail edge do at what rpm ect

[@3ftDeepChannel]

Thanks for your video suggestion. Until we make such a video, we suggest doing a Google search to answer your question.

[@warlordmel]

Doing it like you did, is that "added" pitch or other way around?

[@3ftDeepChannel]

We increased the pitch so that the impeller pushes more water. When you have excess power available you can "ask more" of your propulsion system by making it push more water out of the jet. More water out of the jet pump means faster machine (at least in theory). Thanks for your comment.

[@NZRFoster]

Excellent video!!

[@3ftDeepChannel]

Thanks!

[@michaelmcgowan764]

I understand people change the pitch to increase rpm and top speed, but does this affect acceleration?

[@3ftDeepChannel]

In theory it can, if you have the power behind it. Thanks for your comment.

[@mcoffroadinaz4075]

FYI, 1mm should be around 100rpms difference. Nice vice fix for quick redo.

4:01 you put loctite at the base of the bolt where the nut will never reach, dumb move. also who uses grease AND oil??? without a before and after this is completely useless because it doesnt tell us what this achieved.

Good catch! He put more Loctite on after, but for the sake of brevity I didn't include those clips in the final version. I think the point is made, though. To answer your question, Chris used both. Not recommended, but seemed to work fine. He also doesn't replace screws as required in the service manual ...also a “no-no”. Thanks for your comment.

[@Hiperf]

I have a 2007 155 na with a 11/19 recommended Solaris impeller. I noticed WOT i only see 6700 rpm. What i did find was topics on repitching the impeller to allow more RPM. Is this correct? My only other thought was it was a rental possible and turned down to a certain rpm but i can see 7500 out of the water on a garden hose. No its its not on a rental or learning key that i know of. I do know the speed spinner is broken. No speed shows but i don't think that plays into it. I did install new plugs when i got it. No service codes. Not sure what to try. Bought it with a bad wear ring so i don't know how it was previously. Only paid 1k for it with 77 hours.

[@3ftDeepChannel]

You should see over 6700 RPM on the water. It’s hard to say what the issue is, but I would suggest running for stock OEM impeller. If you can pick up a used one that would be the best next step, in my opinion. You should also pull your pump and check the grease inside and make sure the oil seal is still good and no water is getting in. There could also be some worn parts in your pump that are limiting your RPMs. Good luck.

[@Hiperf]

@@3ftDeepChannel I have had the pump off and the grease looks great year after year. I changed it last spring also. Bearing feels good. New wear ring with no cavitation. Ski runs great. Good hole shot just can't seem to see over that 6600-6700. Perfect no wind glass conditions it might hit 6750. Bought the ski with a broken wear ring actually spinning so i don't have anything to compare too. Specs on pump and wear ring to impeller are good. Nothing out of wack there.

[@3ftDeepChannel]

Okay, then. Seems to me you're losing power somewhere. Have you checked the compression of your cylinders?

[@Hiperf]

@@3ftDeepChannel i did when i first got it. They were a little low but i did it cold and they said that would cause lower readings. Never checked warm. The most i have found was wrong pitch. 11/19 should of been more like 10/18. 10/18 would allow more engine rpm. Roughly 400+

Solas 15/21 too steep for stock 215RXP ? Intake and exhaust mods planned shortly inc Riva upgraded intercooler. thoughts?

[@3ftDeepChannel]

I'd do the mods first and see if you have more power at the high revs to spare before changing the impeller. If so, it may be okay but it still may be too steep. Here's a thread on a forum on the topic: www.seadooforum.com/showthread.php?41344-RXT-215hp-impeller-pitch. Good luck.

[@literbikedoc]

Thanks. Repaired stock impeller for now and replaced wear ring. With stock 215hp engine I'm pulling 7900rpm @ 113km/hr indicated (70mph appr)so I think we have a long way to go before we can spin a 15/21. PS thanks for link. Pitch gauge ordered via Greenhulk PWC. keep up the great work !

[@Redrockat]

obtain from greenhulk

[@Redrockat]

Awesome video ,how did the ski perform after re pitching ?

[@3ftDeepChannel]

We gained 1 or 2 mph. The key is that it's only useful if you have more power that the steeper pitch of the impeller can work with. We got more power by adding the intercooler. Without adding the intercooler to get more power, increasing the pitch will only make the impeller work sub-optimally, and you may lose performance at certain speeds.

[@Redrockat]

+3ftDeep thanks ,that's awesome . I have a stage 4 seadoo rxtx 260 RS with 400 hp . gonna do the 300 stage 4 supercharger upgrade . Ime currently running 77 mph at 8600 rpm ,in "play" setup . got 90 mph on 10500 rpm but that's taking strain on the motor . hoping to get 77 mph faster with the 300 Hp stage 4 charger for better play . Ime using a 15/19 on the ski now and probably gonna take out a shim from the cone or pitch the prop again ,

[@AWDn0t2]

you applied the loctite too far back on the pump assembly studs. put the lock tight on the first few threads, that way you run the nut over the Loctite and carry the Loctite down the threads as you torque the nut.

[@3ftDeepChannel]

Good point, and thanks!

[@findvoltage]

You responded to that is almost as stupid as my comment whining about it ! haha.

Never Ever put loctite on impeller if you plan to take it off again.

[@3ftDeepChannel]

Nope. It’s that newfangled metric thang.

[@AlekBoo]

What about a cavitation after this "tuning"? I think the impeller don't like this.

[@3ftDeepChannel]

That can happen, but the main issue can be increasing the pitch too much so that you can't reach the maximum RPMs. You've got to go in small increments to make sure that doesn't happen. The "tuning" should only happen when you've increased the power of your machine (e.g. added an intercooler), and you can now afford to create more resistance for the impeller to give more thrust.

Yes Jack , when high speed spinning part are to be balanced, the tolerance is in that resolution. I know this from practice , but you can check internet and read about it.

[@jackfrost2146]

If that was true, model jet turbines spinning upwards of 200,000 rpm would need to be balanced within 1/1,000,000 of a gram. I have made my own marine jet impellers which run at 6,000 rpm and not balanced them at all, with no noticeable vibration at all.
