What to use to smooth out a hook in the hull?

[Harpman]

I have a Nitro Z-7 the hull has a hook in it and I want to fill it in and straighten it up . What's going to be the best thing to fill it in with?

You never answered the questions over on the other forum you asked this question about....if you don't answer the questions that people ask they can not help you..

It has 1/4- 3/8 at the deepest part of the hook. It's around 24" long from start to finish. I had it at a service center and they confirmed that it's not supposed to be there. I'm the second owner and it was a few months out of there warranty transfer time or they would have gave me a new hull. They did off to split the cost with me but I'm not spending another $4000 on the boat that if it would have been a few months earlier would have been covered 100%. The boat is like brand new has less than 50 hrs.

3M marine premium filler or AdTech P-77. You may want to lay some glass down in the deepest part depending on how large the area is. A deep filler spot is not desireable on the running surface. If you do end up with much more than a skim coat of filler I would glass over the whole area. This will keep the filler from breaking out.

This is why it’s expensive to have done. Ideally the hull would be stripped and flipped. It’s no fun spending hours on your back working around the bunks and trailer axle!

[Harpman]

Great!! Thanks for the help, I hope to bring back the performance that it should have. It's like ur trimmed all the way in as ur running wide open.

Some Nitro owners in the same boat as you have "patched" the problem with a jack plate. Not nearly as labor intensive and give enogh leverage to pop up despite the hook. Usually about 8" will do it. You have to make sure your control cables and other rigging will reach and replace as necessary.

How many sq. feet are you going to have to correct?

[Bruce2]

Going to have to grind all the gelcoat off also before you start filling in the low spot.

If a set back plate would get the bow lift and the speed up I would much rather do that!!! I would love to talk with someone that has had results with this if ur out ther Orr know someone, hit me up. I have put a 6" set back on it and it made a tiny difference but if it takes a bigger one to get results I'm all for it!

I would get another boat honestly. Just my 2 cts....

Harpman, please share some photos. I have never seen a hook in the pad area of a new or semi-new boat. I've seen some bad hooks, but those were results of years and years of poor support on the trailer. Is it all in the pad or some of it at the lifting strakes and chine areas? Here is where a photo would be worth more than a thousand words.....Gordon

u cant do it right-side up. the faster u go the hook will have more negative effect. boats with hook bottom u find on the back 40.

I will get some pics when I get it back this week from the bps service center. U can see it easy even without a strait edge

Sounds like your bottom is in too bad a shape for the plate to patch it.

Gordon, do a google search for "Nitro Z7 hook" and you'll get enough hits that I'm surprised there isn't a class action lawsuit! Many of these hulls suffered a manufacturing defect related to the hulls being removed from the molds too soon causing a hook. Seems like Nitro did replace a few hulls but many guys got stiffed...

[Harpman]

Yeah it sucks!! The made me a offer that they would do it for $4000. I don't deal like it's fair a known poblem

[Will hedrick]

Sounds like you need an XD 20 bullet, or an 03 allison since you probably do fish out of it,you can get good prices on a used model in great shape, nitro does have wood in the hulls, so a bad pad could lead to bigger problems later down the road.

[Glastron1987]

Not sure why a new boat would have that issue, but stuff happens. I never had to fix anything like that, but it seems if you could get the boat upside-down you could do a great job fixing it with relative ease with some epoxy and fiberglass.

Something to do with the hulls being removed from the mold before they were fully cured, and possibly floatation foam still expanding during that time. There are a bumch of threads about them in the bass boat forums.

Seems like if the company wants to stay in business it may want to consider covering it regardless of the warantee period if it can be tied back to a manufacturing defect like that.

[nitro_rat]

Apparently many original owners that were dealing with uncooperative dealers traded off the boats. The second owners in many cases didn't jump through the appropriate hoops to transfer the warranties. I know a few hulls at least were replaced but many were not and are still on the market. Apparently Nitro is comfortable with their current market share.

Too bad.
