I decided that I need to take the cap off my BL Capri to redo transom and stringers. Now, what are the things I need to look after when taking it off. What are the steps and gotchas. Can somebody put it in bullet points?

If you follow some of the projects I'm sure you'll find one similar to yours,
don't saw through the hull.:)

Re: Taking the cap off

1.) Remove rubber bumber material
2.) Remove Screws or Rivets. (If rivets, you will need to drill them out. MAKE SURE to use the minimum size drill bit needed to remove the rivet. DO NOT drill the Holes over size. You will need to Re-Rivet the Cap so the Hole size needs to stay the same. You may need to utilize a punch and a Roto-Zip tool to grind the heads off and unch out the rivet shafts. Tedious work and Lots of em')
3.) Check to see if any type of sealant has been used to seal the cap to the hull. If you you will need to use putty knife, pry bar or some other type of implement of destruction to remove whatever was used to make this bond. Typically this is NOT much of an issue.
4.) Cap and Hull are now separated.
5.) Slide 2x4's under the cab and use man power or mechanical system to lift cap off the hull and set it aside until your project is completed.

Not to bad Just LOTS of Rivets to deal with.

Welcome to iBoats and Good Luck on your project!!!!!:)

Re: Taking the cap off

I was also very hesitant to take the cap off, but it turned out to be a pretty easy job. There was a lot of hidden rivets in the stern of the boat. Also, underneath the splash well where the cap and hull connected was a thick foam product. In the end it was what was holding the boat together after all the rivets were out. I had to chip it off and then use a small flat bar to try to break the seal.

Overall, it went ok.

Re: Taking the cap off

It is a piece of cake. There are about a million screws that are under the rub rail. Double check everywhere fro screws.

Re: Taking the cap off

Funny, I'm doing the same thing today and got it close to separation but still trying to get my back section separated...I had to remove some aluminum drain tubes that were installed by a custom tool that mushroomed the 2 together...then sawsall the joint under the engine at the transom...close but not separated yet...frustrated at this point...I believe my bass boat was built with care but only took an idiot to ruin it in a short few years...it's glad to see you figured yours out.

Re: Taking the cap off

My Capri has rivets, so if yours has screws you are all the better off. On with the list:

- Use a large flat blade screwdriver or chisel to pry out the rub rail from the housing. Do it a few inches at a time, as they are quite pricey to buy new, so you don't want to ruin it. Heating it up beforehand will made it more pliable. If you have a helper, use a heat gun a few inches ahead of the "pry man" as you work your way around.

- Using a drill, you will need to remove the crazy amount of rivets used to hold the housing in place. Be sure to use a drill bit as small as possible so you aren't enlarging the original hole. You simply plunge the bit through the rivet head and the head will stay on the drill bit and the rivet body will drop inside the boat. You need not remove the rivet heads from the bit until it becomes too clogged to use (this way saves time).

- Capris have a support in the back which go from the lower transom vertically to the swim deck. You will need to remove the stainless bolts where these verticals meet, as the upper portion is part of the cap. You Capri may be different, but be sure to check or your cap won't be going anywhere without damage.

- Using a razor blade, run along the length of the cap in order to cut the rubbery bead between the cap and hull. Your Capri may not have this, but probably will.

- It is easiest to lift the cap using some rope thrown over a branch or a rafter and tied to a cleat, as the cleats have pretty even balancing. If you don't have a rafter to help your lifting, just give the cap a strong heave ho upwards and it should break free from the hull.

IMPORTANT: When the cap breaks free from the hull, the hull will quickly spread much wider. This is normal and is not dangerous to the hull, but be sure you are ready for it, as it is not something you can just hold in place with one hand.

Feel free to check out my resto thread for a few images of how I lifted mine.

Hope that helps.

Re: Taking the cap off

If this weather would cooperate a little bit, I could have done it this weekend. I have rubber out, rivets out too. Now I need to remove the engine first. I don't know how to remove this cable that I am showing with my finger in the photo. I guess it is stearing cable. What is the procedure for removing it? Couple of pics of engine stand I built, and a rig to help me lifting the cap are attached too.

Re: Taking the cap off

Just bought a cherry picker from ebay. Figured, I might be better of just buying the darn thing for $100 then renting it for $40.

Re: Taking the cap off

This was supposed to be the easiest part, taking the hull off. Spent whoooole day trying to get it of. Started at the front and was able too pull it up some 1 inch. Then I moved to the back and this thing is not coming off. I am able to raise it again about an inch on both sides of transom, but middle section is not separating. I am afraid that it is too tight that it cannot come up. Anybody had a situation like this. All rivets are out, all screws are out, and the darn thing is not moving.

Re: Taking the cap off

I'm surprised you've been able to move to cap with just the fasteners for the rub rail out. My thunderbird had a whole set of rivets just for holding the cap down under the aluminum channel for the rub rail.

Re: Taking the cap off

I took all of the rivets out last week. There were hundreds of them. I can pull the hull all around with my hands and put a fingers under the cap with no problem. But I cannot take it off.

@rockyrude: I re-read your post and are you saying that I need to remove aluminun rail first?

Re: Taking the cap off

If you have removed the top half of the cap from the hull in the front, then my bet is that you dont need to remove the aluminum rail, however having said that my 'Twain did have screws under the rail. Furthermore, to remove the rear portion of the cap from my hull, I had to put a hydraulic jack under the splashwell and pop the cap from the hull that way.
Hope this helps!

Re: Taking the cap off

That's a good idea, I'll try that. I am just afraid not to crack anything. On some areas, when sun hits it, even through gell coat I can see the light.

Re: Taking the cap off

Just remember, if you do use the 'jack' method, be sure to put a piece of wood (large piece of ply) about a square foot between the top of the jack and the splashwell so that there is not too much stress on the point where the jack contacts the splashwell.
Hope this works for you!

Re: Taking the cap off

That did the trick. There was some glue I guess between the cap and the transom. It was pink and smelled like bubble gum. So no off to first taking the transom apart. Thanks for you help
