Super Jet what is this on my hull?

[davy87nj]

So had my ski on the davit today, For some reason no matter how I ride this thing it still hops alot in the water. Maybe I weigh to much and im not doing it right. But I noticed this on my hull. Mounted very sadly with 3 screws and some cheapy auto sealer stuff. Im hopeing there isnt a hole or soft spot underneith it. Sorry for the bad pic, but it looks like a 'tubby' type deal underneith the hull right before the intake grate. Im wondering if this is causing my rocking and hopping, along with stability issues. Thanks

Just remove it. Then take a picture of it in the garbage.

will do tomorrow for sure. how could I seal up those holes from the screws? I was planning on stripping the hull down and painting it after this summer. Could I used 5200? or epoxy?

5200 will take a week to cure

That is what was known as a vortex bubble. They were popular on race skiis back in the early 90's
just remove it and fill the holes with marine-tex.....
I would say its probably the cause of your issues

I just bought the marine tex. Took it off. took for a quick ride and it rides much better. still hops at speed but i can turn so much better. Thanks for the info.
