GreenHulk GP1800 / VXR Intake Grate Shootout

[K447]

Any of the intake grates will install the exact same way!!!! Two bolts in the front/Four bolts in the back and they all fit the same hull

I wanted to see what they said about sealing.

I wanted to see what they said about sealing.

They say to put a bead of "The Right Stuff Sealant" around each of the bolt holes, just like the RIVA instructions.

Those of us that know better will want to run a bead of silicone along all of the grate surfaces that mate up to the hull, not just around the bolt holes.

Just received my Riva Intake Grate from Jerry and all I can say is wow. It is a very solid well built grate compared to the stock. Can't wait to try it after snowmobile season along with my other winter Mods.

Damm I just tested my R&D grate and seal kit, cavitation is horrible, really bad. Should have bought Riva.

Is the intake grate actually and fully sealed to the transom plate and to the entire width of the front edge of the ride plate?

Ventilation may be the problem, if there is an air leak path (even a small one) from anywhere below/behind the intake grate, up into the water flow path through the transom plate.

yes my friend.

I ride offshore and I'll likely just be adding a tune and handling components to my stock ski (the conditions don't really lend themselves to speeds over 80 mph). I definitely want to swap out the ride plate (haven't picked one yet), however I'm struggling on the intake grate, as there's a healthy amount of seaweed and other debris in my area. I'd like to improve hookup, but worried about sucking in a bunch of junk. Thoughts?

Without a doubt go with the Riva intake grate. The RIVA grate will not, nor will any other grate cause you to suck up anymore seaweed than normal!

For offshore riding the WORX ride plate is hard to beat!

WORX Ride Plate for GP1800 and 2015+ VXR Worx has created a ride plate that is more predictable on turn in, letting you enter the turn with more speed. It sets the ski up, keeps the back of...

I thought going with a top loader grate increases the chance of sucking up more debris. There is a larger opening that can now allow larger objects in? On Riva's website they state that the probability of pulling something in is greater?

No, there is not a greater chance of sucking in more debris. Below is the product description of the Riva intake grate. Nowhere does it say anything about pulling something in is greater.

Our revolutionary new intake grate for GP1800, VXR and VXS delivers the ultimate in speed, hook up & strength. All new design features oversized top loader wing and optimized inlet ramp for closed course and offshore racing. Bulletproof stainless steel construction makes this grate virtually indestructible and eliminates the need for additional restrictive support bars. Race bred design significantly reduces cavitation and provides superior handling along with unmatched durability in extreme conditions. Key Features:Dramatic increase in hook up due to new top-loader wing design & inlet ramp
Improved top speed in rough water conditions
No top speed loss on smooth water
Race bred design provides excellent handling
Significantly reduces cavitation
Bulletproof stainless steel construction tested at 90mph

It is under the review/questions for the grate. I just don't see how a wider opening would not have greater chances of pulling something in? Things that could not fit in before now can instead of being deflected away?

Q: I like to ride in areas with higher possibilities of debris (sticks and vegetation). Will this design make the possibility of pulling something in greater?

Well, they gave you a stupid answer. ANYONE with any experience using any of the scoop type grates will tell you they do NOT have any issues with sucking in any more debris then normal. The scoop grates simply channel the water that's already coming into the pump anyway towards the top of the pump increasing pump efficiency.

I may have missed it but what were the numbers on the stock grate? That’ll help me decide more on buying another one ��

[fx160]

It probably does let more debris go through the pump
But a stock great grate will clog with debris and you will have to get into the water to clear it
