So far I have always used Yamaha OEM oil filter 5GH-13440-61-00 and Yamaha OEM WaveRunner Boat Oil 10W-40 4W. This is more expensive than compatible filters and alternative oils, but given the investment in the machine and believing in the importance of high quality lubrication for modern...

A female flush connector came stock on my 2022 superjet (see first pic below with cap off) and similar is on an 2009 FZR. I have a flush kit and you can see the male / connector adapter that plugs into the skis pictured below: I am in the process of adding a flush capability to my '96...

Hello, i have a single mikuni sbn 44 carb, 61x case and 61x cylinders, i have a factory b-pipe. idk for sure but i think the head and domes are like stock. I guess also i should mention that i have a lowered hood and so I think maybe the ski still has the stock air intake filter and cover /...

Hello, I have 701 with 61x case and 61x cylinders (and so single mikuni 44 carb) with factory b-pipe. I would like to install a connector / adapter for an external water hose so that i can try to tune the carburetor settings while on a stand. I have looked but cannot see where there is any...

In October I will be staying in Fort Lauderdale area for a few vacation days before boarding a cruise ship. Does anyone know of anywhere that has stand-up ski rentals thereabouts? Or is this just not a thing there is?

Hi, I have a 1996 RN with 701 61x/61x engine with a b-pipe, and so a single carb. I am replacing the carb with a Mikuni SBN 44 that I bought from a guy who said he had bought it new and set it up for use in a super chicken which I think had a kawi 750 engine. Apparently, it was used for this...

Don't know why but just watched this installation video for rrp ninja flow guard: Rickter-RRP Flow Guard Installation Guide for 144mm and 155mm What is the purpose of the guard?

My SJ4 is taking on water. If i ride it for about 20 mins it can have as much as 3 inches depth in engine compartment, so we are talking about many liters in just that time. I secured it to a jet ski lift and let it sit for half an hour or so, and there was barely any water at the low point...

A few weeks back I swapped SJ4 stock impeller for a Solas Concord to go with a stage 1 type tune (using maptuner nano). I have been doing some other things with it as well and so today was first time I ran it to warm it up to do an oil / filter change. I noticed what seemed like a metal...

I am embarrassed to say but as of this moment I have misplaced the 4 bolts that fasten the reduction nozzle to the back of the pump case. I am hoping someone can please tell me the exact specifications for these in case I need to replace them tomorrow?

Trying to upgrade the stock impeller on my 4-stroke SJ, and have removed the 5 bolts that fasten the pump casing to the rear of the shoe, but the casing is sealed on there super tight. I have wacked it with a rubber mallet and tried to pry it loose but so far no joy. Any tips for how to get...

what do you figure is best way to connect electrical wires for say connecting up bilge pump switch? not meaning for multi-pin type applications. i have always soldered and shrink wrap, but do you figure there is a better way?

I am changing the impeller on 4-stroke superjet. 1.a) When i re-install the reduction nozzle to the pump body casing it looks like i should use silicon or something to make seal; is that right and if so what is best to use? 1.b) Similarly, when i re-install the entire pump body back onto the...

Besides either the Riva intake kit or VK Composites plate, does anyone know of any other alternatives for a mount plate for ECU and electronics that allows for elimination of air box, that doesn’t include filter or breather?

I would like to change the color of my 2022 superjet hood. What material are those hoods made of? Could this be painted in a way that would work out well over time and stand up to the elements? If so, what type of paint should i use; would i need a primer, what application method, and what...

I have been looking at the Riva Stage 1 upgrades for the 4-stroke Superjet. I have a Kommander intake grate. 1)Any performance benefits to installing just the Riva intake and exhaust upgrade kits without getting the ECU map flashed with RIVA Stage 1 using Map Tuner? Any numbers for such...

I was hoping that y'all could help me identify my superjet. I always thought it was a round nose around 1996 but i recently read on wikipedia that all the round nose superjets came with 701 engine and 61X cylinder, 62T cases, and so then dual Mikuni Super BN38 carbs. Mine has a 701 engine but...

I would like to try destroyer front sponsons on my 1996 701 superjet. It has dual exhaust and so to do sponsons I guess I would have to eliminate the front exhaust. I have a B-pipe and 701 engine with a single mikuni 44 carb. Are there any issues with regard to getting rid of this front...

Launched my ‘96 SJ701 yesterday and rode it not too far from launch to my place and messed around there a while. I was off it once or twice and so had reinserted kill switch key and restarted a couple of times no problems. I put it on the lift thinking to adjust carb a bit as this was first time...
