Lucky 13 adjustable pump cone

Just ordered Do you guys reuse the same oring or put a new one on there?

People here seem to reuse the o-ring without consequence. Just check it over to ensure it is uniformly round with no nicks or cuts, also pick up some o-ring lubricant (Parker Super O-Lube) if it is not lubricated well. Helps with install so you do not roll it during cone install.

Lucky13 on its way! Can't wait to get this puppy on my 190! My thanks goes out to Jerry @Green Hulk for a great deal.

I’m wondering the same. Lotta money to experiment with !

Any benefit to using the L13 comes in a 210 with the TR-1 engines? Everything I’ve seen is people running these with the 1.8L. Most interested in improving fuel efficiency at cruising speeds (~25-28mph) and top speed.

Is this discount still valid?

 

[Canuckjetboater]

Dammit!! I just bought one last week and installed it. Day late and a dollar short, lol. Its a great product for dam sure. Every yamaha boat should have these by default!!

@S1LV3R4D0 ......you've had your cone for awhile now. Do you still recommend it? What setting (ring mm) would you recommend if most of my RPMs fall in the 5200 range. My engine and hull are very similar, if not identical to yours, as I have a 2020 Yamaha SX195. Thanks!

 

[S1LV3R4D0]

As long as you are not at any high elevation, yes i still recommend all 3 rings @Canuckjetboater. Im not a speedster so the top end doesn't bother me much. But zero issues with cavitation getting wakeboarders up and pulling tubes.

@Canuckjetboater I'm on my 3rd season now. Been running all 3 spacers until a few outings ago. I dropped the red spacer.

99% certain I'll putting even MORE spacers back in there. Definitely going to put the red one back before my next outing as well. Cavitation on turns got worse with fewer spacers.

You have a larger pump (160mm) compared to my smaller pump (155mm), and my understanding is that the 160's don't cavitate as badly as the 155's do. SO, your mileage might vary. I would start with all 3, give it a few hours of usage, then start pulling them out again until you have unsatisfactory cavitation, and go back one step. Make sense?

 

[Canuckjetboater]

@S1LV3R4D0 and @2kwik4u .....thank you very much for the prompt informative responses. Very insightful and helpful! Cheers!

 

[jgourlie]

Has anybody thought to try 2 blue spacers and 1 yellow for 11mm of spacing instead of 12 with the red?

I am just wondering if 11mm instead of 9 (by dropping the yellow) might keep the rpms and the cavitation elimination?

or just 2 reds for 10mm even?

Hi guys, I wanted to introduce myself. My name is Jerry Gaddis and I own the PWC Performance Forum GreenHulk.net and the Performance store, GreenHulkStore.com

I am a retailer of the Lucky 13 adjustable pump cone and I wanted to tell you guys a little more about this product. One of the forum members here, Swatski, has done extensive testing on his boat with this cone and has shared lots of valuable information about it here on this thread

https://jetboaters.net/threads/lucky-13-l13-anti-cavitation-cone-install-2016-ar240.12099/

These cones work amazingly well on the Yamaha skis and of course the Yamaha Jet Boats. These cones work well to prevent cavitation, especially when at full ballast and pulling skiers. They are also tunable by simply adding or removing spacer washers this way you can fine tune the cone for your boats weight and normal capacity.

Here's a short video I made telling a little about the cone.

There is quite a bit of interest on this cone lately so I have agreed to give the Yamaha Jet Boaters members a $40 discount off of each cone. To get the discount, leave a note in the comments box of your order saying "$40 discount per cone, per Jerry" and we will immediately refund you the discounted price once the order comes through.

Those with Naturally aspirated boats will use this cone

What did it improve top speed? Lower rpm at top speed?

 

[Jerlane]

I have the lucky 13 cone installed with all three rings on my 195s. I'm still seeing a lot of cavitation when turning while pulling tubers. Has anyone tested them out with fewer rings on a 195? Results?

Thanks!

This is my first post here, we just purchased a 2024 ar195. We also own a 2011 seadoo speedster 255hp. In comparison the seadoo has none of the problems we have experienced with the yamaha. The speedster has like zero cavitation problems, it's literally hooked up all the time unless I spin the boat out or just do something stupid. The yamaha has cavitatated from day 1 and I've been trying to fix the issue. Replying to the previous post, I've resealed the pump tunnel and smoothed out all imperfections or anything that could effect air or water flow. I've checked the clean out port and it's seal; from what I can tell it's not leaking. I've filled it up with water and the water stays there for days until I pull out the port. I also looked for missing sealant around the transom and added sealant there. A whole day on the water there is zero water in my bilge or hull and I still have cavitation mainly trying to turn the boat at speed. Hole shot is good but definitely slippage there to. My impeller and gaps look spot on. So now I have a lucky 13 on the way....I can't think of anything else. Yamaha imo could do much better, should not have these issues with a brand new boat.

I have a 2023 AR195 and do not have any of the issues that you mention here.
Good Luck in finding the problem as it sounds like you have done the normal things.
I'm sure you will get more advice from the very knowledgable guys here!

Sounds like you got one that was built right. Unfortunately, the consensus is that these boats seem to have history of the issues I mentioned. Or maybe I might be more sensitive to how the boat is reacting since I have comparison to another boat. I've had jet boats since the 90s so I'm pretty in tune and have an expectation of performance. Top speed is not an issue, I hit 47-48 on average with another passenger and gear but if I try to turn the boat going anywhere near
40mph, I feel her loosing grip and pull back on the throttle considerably so the pump can load up.

I suggest getting Cobra Jet steering added. All aluminum and the fins stay in the water unlike ThrustVectors which rise up. I put they on our boat and they seemed to help some.

to clarify, they seemed to help with higher speed turning...

 

[birddogdaze]

I heard good things about the cobra fins; I'll likely go in that direction if I feel i need more. Having more control is always good thing. Thanks for the suggestion.
