almost like a defective original base under the paint. Frequent beaching would not look like that, would it?

This is what I'm thinking as well. The rest of the hull is spotless, including the port side.

You can clearly see that there's layer on the actual hull material gone. No amount of paint alone is going to fix that.

I disagree. A couple of coats of a high build high quality marine epoxy will work well.

Yikes! That looks terrible! I hope that the SMC hull will avoid such problems moving forward...

That pic shows a crazy amount of peeling, almost like a defective original base under the paint. Frequent beaching would not look like that, would it?

Looks repairable to me. Hard to say from the photos, but I think a couple of coats of a quality high-build epoxy-based marine primer/undercoat would seal it well, followed by a couple of coats of your desired basecoat on top. Maybe even a couple of clearcoats on top to finish it up if you feel so inclined. You said you're fairly handy so you might even be able to do it yourself. It's the hull anyway so it's not as if it's going to be particularly visible.

Thanks. I should be able to get this at a very large discount. Where even if it ends up being a 2-3k repair it will be worth it. Good idea to check with a dealer, I wasn't sure if it's something they would work on. I'm not familiar with these hulls, so as long as it can be repaired somehow i'm OK.

One of my ski's is Nano with 230 hours and the hull looks great. Hard to believe that one has only 71 hours and it peeled like that.

Seems like the top layer of the hull is gone. It could be fixable, however there is no telling how far the damage extends to. Anyway it requires a lot of work, if I would touch that I would pull the engine and flip the ski upside down. I woudn't buy that unless I got it for really really cheap, like the price of the engine and pump.

Thanks! That's the goal, should be able to get it pretty cheap.

There are other hull materials, used by other brands, that also need epoxy type repairs. Not just Yamaha with NanoXcel

I have posted NanoXcel repair notes in several threads on GH.

I presume you cannot water test it before purchase, so it is possible the PWC has other issues. You really want someone who really knows these machines mechanically to inspect it with you, or for you.

Thank you, this gives me enough to go on now. If this one doesn't work out, this will be helpful regardless

I have a lot of experience with the 2 stroke GPs and GPRs, and a lot of experience with other 4 strokes (drag bikes, SxS, motorcycles, etc) but have not worked with these before.

This would make the most sense based on what I'm seeing. This appears to be more than just paint peeling.

I'm going to assume right now it will need this epoxy layer.
Are there shops that do this work?
Or is it a "stay away" type thing?

Search GH for references to the web site

In addition to the above web site there is a related PDF with hull repair info from Yamaha.

Clearly the hull needs to be properly repaired.

One possible alternative is to purchase a good hull that has a blown engine.
Or no engine

Then transfer the mechanical stuff from this damaged hull into the good hull.

If that layer is gone then the repair will require coating the surface with a layer of epoxy to bond to the fibre reinforced core material.

Have you seen this hull in person?

it may not be just paint that is peeled away. NanoXcel hull material has the thick inner core material, but underneath the paint is a hard smooth layer. Kinda like gel coat, but not actual gel coat. If that layer is gone then the repair will require coating the surface with a layer of epoxy to bond to the fibre reinforced core material.

Also note that NanoXcel 2 material differs from NanoXcel original, and both differ from traditional fiberglass and from traditional SMC. Different repair methods and materials.

I have not seen this in person, it's a several hour drive. Right now I only have this picture to go off from. These NanoXcel 1 and 2 hulls are new to me, trying to do my research before I commit.

As long as it can be repaired somehow is my main concern. Most posts I have seen in my research don't cover this type of issue.

idk if the paint seals the hull if it dosent id run it all summer as is then send it to a shop to get redone this winter. i know my local dealer has a paint shop that they use so you may want to ask your local dealer who they use

oh forgot to add that looks to be a 1500 repair btw- so id take 1500 off their price!! also if they are adding the riva stuff to the price id make them subtract that as well plus another 1000.00 the riva stuff devalues the ski UNLESS they had it installed by WFO / butter or GH Jr (LOL the newest on the scene) that you can call and talk to
