Thanks for the replies. My FX it has a rubber dampener of some kind that fills the void between the motor mounts. So I’d have to hit it with water from the side. Luckily I was finally able to get an...

So I dropped my bov fitting in the hull. And I’ve tried off and on for a week now to find it and have been unable. This isn’t the first thing that’s fallen down there, but it is the first object I...

Nice to hear Yamaha got you all fixed up. Any idea what’s gonna happen to the broken ski? I’d purchase it for extra parts at the very least.

Agreed. I find the FX to be nimble for how big it is. I like to slalom through the bridge pylons around here and the FX does well enough that I feel like I will fly off before I need to slow down...

My FX has zero cavitation from a dig or turning hard. It hooks and goes. No water in the hull either. I haven’t touched anything other than doing the ribbon delete. My GP with the solas impeller does...

Mine is a 22 and has done it since day 1.

My FX also does this, my GP does not. You can’t keep the alarm silenced. It will beep, you have to stop driving, press ok, but as soon as you start moving again it goes back off. It’s very annoying. ...

The winterization is typically more directed to skis that will be stored outside or will see sustained below freezing temperatures. Any water that ‘MAY’ be trapped has the potential to expand and...

I’m fairly certain he meant traces of fuel in the oil. Outside of someone putting oil in the fuel tank, oil isn’t going to go backwards through the fuel system.

It’s on the vertical surface and shielded by the cover panel. We have 11hrs on the ski and I haven’t seen any indication of water ever getting behind there. Riding strictly in salt water it would be...

Got around to installing.

Thanks for that info! I’ve been looking into the retainers recently. Probably have a few more weeks of riding weather before it gets too cold. Still mid 80’s during the day.

My 22 FX with breather, ribbon delete, and stage 1 on gets 72. I don’t have the riva ride plate, but I don’t think it would get me to mid 70s.

I used this because nowhere local had the 4200.

No problem at all. Did you get everything apart? Do you still need a picture of where I used for prying?

I was able to take my ski out last weekend and not one drop of water was in the hull. So I...

Have you checked the timing? Who rebuilt the engine? Are you sure all valves are in good shape and seating properly? Do you hear any air blowing out while it’s spinning over?

I was glancing earlier. I see a few made for overhead valves that look like they would work with the head on. If I have to break the head loose I’m going to be pulling a lot more while I’m in there....

Any recommendation on what spring compressor will work?

A turbochargers boost can be manipulated using a boost controller. A supercharger makes boost based on engine rpm. So you kind of get what you get with a supercharger. Turbo you can use a boost...

On the two bottom holes I used a flathead screwdriver to gently pry between the transom and pump housing. You’ll hear the silicone starting to peel off. Just keep your pressure even and you’ll be...

I already have a maptuner. I know with the higher compression ration I’m looking at lower overall boost pressure, so I would be looking for a turbo that spools quickly as opposed to one that makes a...

No one? :(

Valve stem, like for your tires. Works the same as a pinstripe removal wheel.

Im in SW Louisiana, I have the same weather as you. Haha

I fully agree 100%, no ski under 10 years should even...

You can use 3m black silicone to reseal the nozzle. I don’t think it would be a problem using 4200 other than it might be more difficult to remove if you need to disassemble in the future.

I...

So I’m considering a winter project of turbocharging my GP HO. As the title suggests, how do I go about doing this and keep some semblance of reliability? My goal is to get above 80mph, but I don’t...
