DIY Yamaha Superjet Wide Tray - Jetski - RSKI RIDERS

[@willmsm1]

That is some impressive work on what looks to be quite a daunting project! This team has made an enormous contribution to the sport and to the generosity so celebrated in its culture. They are among the many who do not think twice about helping riders at the beach who are enthusiastic and eager to learn the surf. Much love, respect, and gratitude boys!

Thanks for the kind words! The freeride spirit lives on! 🤙

[@RSKI]

His name is Felix. He’s scared of most things. Good cat though. 🤣

[@frankdieber7090]

That was sweet. Iv been out of the game for over 10 years but now my kids are just getting old enough to start riding. I’m in the middle of putting one of my old race boats back together for them. Haha I’ll be buying stuff from you soon

[@RSKI]

Thanks for the encouragement Frank! Hope you can get back on the water ASAP! 😊

[@Superjet_360]

Great work! I doubt that I will ever have enough courage and patience to do something like that.

RSKI activities 😂

You have one of the coolest Jetskis on the planet! (In my humble opinion) 😆

[@fr2surfboat]

Awesome video guys!! Very informative and entertaining! Thanks for keeping the Superjet vibe alive!!

[@RSKI]

Thanks for the kind words Todd! We put a lot of hours into this one!

[@FloridaBoatRamps-88]

Greetings from Florida!!! Thanks for sharing!!! 😀😀

[@frodiesel0]

Excellent video here, incredibly informative. I’m impressed by all the small details you guys added. My brother from Kalamazoo hooked it up on my ski and we went just over 24 inches with our wide tray. However, it took over two years to complete as we move the edges out beyond the bond rail. I’m currently putting a fixed steer hood on it and once I am finished, I will make a video and share it here.. or in my channel

[@RSKI]

Thank you for the kind words!!! Best of luck on your project! Interested to see it.

[@davemikulski2593]

Great video and nice work. Were you concerned at all about changing the angle on the exhaust tube? Looks like the 3" drop was considerable, and was wondering if water can now backflow into the engine. Thanks

[@RSKI]

Hi Dave, with the engine off the ski does sit in the water differently since the exhaust tube fills with water more than normal. Haven’t had any issues at all though

[@davemikulski2593]

Glad to hear it. Thanks for the response.

[@waywardriley]

Stu (and his cat) made me cut my tray. No regrets.

[@RSKI]

Felix the cat should be in the next video.

[@henrytischbein155]

Could I use carbon fiber instead or of fiberglass

[@RSKI]

Ya, although I’d just use one layer of carbon on top to cover the glass for the look you want. Carbon Kevlar has the coolest look.

[@nicholasmendoza6384]

this looks like a sick upgrade!! im looking to get into my first superjet and also first stand up. any advice for riding/ buying the right ski?

[@RSKI]

Thanks Nicholas! For us the round nose Superjet has been amazing. 1996-2020 are all really awesome and you can do some mods if you want. Welcome to standups! I bought my first one in 2012, and it’s a 2000 Superjet. There are a bunch of videos here on our channel about it.

[@nicholasmendoza6384]

@@RSKI yeah i was looking at some of those just wasnt sure to pull the trigger. looks like you got a great chanel here. love watching the videos!! i think i got one left and ive seen them all :)

[@ivanburdin1401]

I was waiting for this video to come out! Great stuff. I am currently refoaming my waterlogged tray on my rockered super jet, totally new to the fiberglass world but have good friends who are helping out. Do you guys know how many cubic feet the widened tray is (for foam calc)? Also, can the 920FS Marine sealer be used on water lines iside/outside of the tray? Is that better than the 5200? Many thanks!

[@RSKI]

Hi Ivan, sorry it took so long for this video. It was filmed over a several month period and a bunch of different jetskis, some of the skis didn't even make it into this video. I think we finished four different wide trays during this time, and we're still finishing one more. This video edit was brutal! Happy you enjoyed it! As far as ft^3 of the tray, we just estimated it, and if you're short just mix up more. I think we had two pours to get the tray full on the black one, and I didn't write down the amounts for that unfortunately. We did use the 920FS to seal the water lines and everything, I think 5200 would probably work fine too. Cheers!

[@CaseyKilby]

Hey where do you buy the fiberglass and epoxy??

[@ryrystewy1]

Are there any types of low profile wide tray footholds that would work with this?

[@RSKI]

Possibly, I remember the BOB adjustable foothold kit I saw many years ago, that might work but we haven’t tried that. We really like the foot straps in the surf. I bet you could make your own kit though!

[@kellyrides429]

How did you seal up the holes were the rivets were for the exhaust?

[@RSKI]

You’ll want to use thickened epoxy and fiberglass from the inside. I usually do these at the same time that I fill the holes in the bulkhead.

[@kellyrides429]

@@RSKI I have another question, I just picked up another SJ and they installed front sponsons, how do fill the holes for those? The same way?

[@kellyrides429]

@@RSKI by the way thank you for your response. Would love to see some new content!

[@slevinkelevra8696]

I'm about to buy one from 2013, what do you recommend to check before buying? I have no experience with jet skis but I have disassembled and reassembled some motocross engines especially the one on my k250, I hope for some useful advice here in chat. tnx

[@RSKI]

Check engine compression and check the hull for cracks or damage. Especially the bottom of the hull. 👍

[@WilliamMcFly]

What is the product you put on the tray on your urethane to "seal it" before install your 1st fiberglass sheet ? i review many time your video to catch it but not sure the product... i hear you take epoxy but want to no what kind of epoxy you take. thx a lot for your comeback !

[@RSKI]

We use the the same epoxy resin used in the fiberglass process to seal the foam. I like to add thickener to help fill the voids in the foam and make everything nice and smooth before the first layer of fiberglass goes down. I should also note that you do not need to wait for this to cure before you start fiberglass, but I do recommend an epoxy with a medium cure rate because it can get fairly thick in certain situations.

[@WilliamMcFly]

@@RSKI what thickener you use to add with the epoxy resin ?

[@nickdean8758]

any chance you can give me some product names/ information that you need/recommend for doing fibreglass work? I can never seem to find anything online about specific products and Ontario doesn't seem to have the same selection as the states. on another note, my SN has the top deck and bottom deck seam separating on both sides of the tray. I have tried to just seal it but water just peels it out. any chance you know where to find longer bolts (that look stock) for the black bumper/trim so I could try sealing it and through bolting the top and bottom decks together? kinda wanna solve this issue before I rip the tray out and re-foam it. (if I ever gain the will to cut up a virgin tray just to save some weight in waterlogged foam)

[@RSKI]

Hey Nick, there are some links in the description for you to get started. Does that help in Ontario? Most of the stuff can be purchased from Fiberglass Warehouse. As far as the top and bottom deck separating, I’d just completely separate them clean out all of the glue. I think the OEM glue is called Plexus. This would be a ton of work, and then reinforce everything and it’ll last a really long time. But a ton of work for sure.

[@nickdean8758]

@@RSKI I guess I should have looked at the description... definitely helps big time even just to know what I need to look for. from what I have read about separating usually the top or bottom deck will break in the process (if I'm remembering correctly) so ill probably just try to band-aid it until I end up cutting the tray out to refoam and add footholds. definitely not worth it (for me at least) right before the season starts lol. Thank you for all the info, appreciate it.

[@RSKI]

Breaking is definitely a possibility, I’ve never tried to separate them actually. But one of our friends has successfully done it. He actually put a round nose top deck on a square nose bottom deck and it worked perfectly. 🤣

[@nickdean8758]

@@RSKI yeah I know jetski brothers have done it, (SN top on RN bottom) but they seem to be wizards and make the craziest stuff work.

[@RSKI]

I think the bulkhead would be the main obstacle. I imagine you’d want to keep the bulkhead attached to the bottom deck, and disconnect the bulkhead connection to the top deck.

[@saltrocket1909]

So is the open space where you didn’t foam so the tray is wider? Why not foam it all?

[@RSKI]

Every place in the tray is foamed, I didn’t understand which part you’re talking about?

[@rentamonkey3911]

Do you guys offer these services at all?

[@RSKI]

We don’t have a ton of spare time so we use that time to make videos to teach people how to do it on their own 😊

[@Floatsorrolls1]

Hey was curious who you guys use for porting cylinders. Erickson Machining and performance has had my cylinder for 8 months. If I can ever get it back who would you guys recommend?

[@RSKI]

Yikes! Hopefully you can get it back soon! We have used Jetmaniac “Blue” ported cylinders in the past, but our current skis are oem stock cylinders with no additional porting work done to them. Highspeed industries has also been a great resource for us and they are usually very quick.

[@matthewrobert2888]

Thinking of doing this to my superjet that i just bought bought it not knowing it was water logged how much did your supplys cost for this?

[@RSKI]

Hard to say the exact price, I guess around $150. It’s more of a time commitment than a money commitment I think. Dive in and get it done!

[@saltrocket1909]

Also I see the build sheet data. I was wondering total cost of this job? Did you only buy 1 of each in description? Thanks!

[@RSKI]

I’d guess it will cost around $150.

[@henrytischbein155]

Do u still have the skis

[@RSKI]

We skill have skis and ride!

[@protorail7]

Great video! Can't wait to wide tray my square nose and this video helps a ton. How much resin would you guys recommend buying to do wide tray and foot holds on one ski?

[@RSKI]

A wide tray and foot straps can definitely be done with a one gallon kit and still have a lot left over. I don’t have exact amounts as we just buy it by the gallon.

[@9avedon]

After the SuperJet, Yamaha came out with the FX1 with a riding tray width of 12 inches. I have skilled riders win the world freestyle by flipping and rolling the FX1.........very challenging. Get your history correct !! A 21inch wide tray is much easier, no doubt about it.

[@RSKI]

Fx1s are super fun!
