86 Starcraft SS 160

Re: 86 Starcraft SS 160

I know it's been a long time since I last posted. Lost a month with Christmas and vacation, but I've been working on her some lately. The hull is sealed, plywood is cut and sealed and my Nautolex will be here Thursday. Complete update with pictures soon. My problem is floatations. I cut and fit blue foam board, but it squeaks like crazy. I was planning on glueing it in place with spray adhesive. I don't know if I should scrap the foam board and go with pour in foam. Squeaking foam under my new floor would drive me mad.
Most of what I've read talked about how much water different foam absorbs. Anyone who has experience with squeaking foam, I would welcome any suggestions. Thanks, eddy622611

Nice looking rig! Prob one of the cleanest during a gut job I've seen! I went foam board in my Sea Nymph resto but the SCs have a different stringer set up. That link shows my foam set up. I cut my pieces over sized slightly then shoved them into place. I also used beads of hot glue to stick them together. Haven't had an issue with squeaking. Bummer about the motor but when all said in done you'll have a great rig to make some memories in!

What about a hybrid sheet foam/pourable foam solution? Basically use the pourable to secure the sheet.

Re: 86 Starcraft SS 160

I believe Lakelover put a sheet of plastic down between the deck and sheet foam and said it stopped the squeaking....

Re: 86 Starcraft SS 160

I used the same method as Piece715 and have never heard a squeak. I used the pink stuff, but that shouldn't matter.

Since you already have it cut, maybe you should use try a little more on top. Enough that you have to force the flooring down a little.

Re: 86 Starcraft SS 160

eddy, when I put foam slabs in my 21 footer, I didn't know there could be a squeaking problem, but I haven't had any squeaks. I didn't force the foam to fit though; it just nests between the stringers and isn't thick enough to press against the floor. It may be that when you try to support the floor with slabs as opposed to pour-in foam, the foam moves against the stringers and adjacent slabs as it takes your weight as you step.

I re-used the original 1/2" floor as it was in decent shape. I think that in 1972, 1/2" was still 1/2" and not 7/16" like today's plywood. I would think that 5/8" would be plenty strong enough in your boat. My 1/2" does have some spring in it, but the centres of my stringers are likely wider than yours. - Grandad

Re: 86 Starcraft SS 160

I didn't have the floor in place. I was just placing the foam. The squeaking was a result of dragging the foam pieces against the bare aluminum. I think once I glue it place it should be okay. Just wanted to ask to make sure that no one had a bad experience with sheet foam and squeaking.
Too often in the past when I would do something and end up with poor results, I learned if I would have asked someone that has done it before. I would have saved myself a lot of trouble. There are a lot of knowable people willing to help, if you just ask. Thanks,Everyone for all your help. Eddy622611

Re: 86 Starcraft SS 160

Here are some pictures of the boat going back together. First I made full size carboard templates. Once I was happy with the fit, I cut the floor out of 1/2" marine grade fir plywood.

Re: 86 Starcraft SS 160

After I had the plywood for the floor cut and sealed. I wanted to mock up the casting deck and trim pieces that I needed to reproduce.

Re: 86 Starcraft SS 160

Looking good!

You sure 1/2" is going to be strong enough? I used 3/4" on my SS....and I'm very happy with the sturdiness of my deck.

Re: 86 Starcraft SS 160

That ski pylon looks great I have one I'm looking at mounting but need some creativity for it to work.

Is there a mounting plan - backer plate or additional plywood?

Nice work on the template and floor. Looks like it fits perfectly.

Re: 86 Starcraft SS 160

Looking real nice, you have a real good fit on the ply.

Re: 86 Starcraft SS 160

Bonairll, The factory floor was only 1/2". I have the floor doubled on the seams and where the seats and the ski pylon mount. Brian

Re: 86 Starcraft SS 160

64osby, The ski pylon was in the boat when I bought it. The floor is doubled where the base mounts, and I am going to make a backing plate out of stainless steel with captive nuts. I'm thinking about moving the pylon back toward the splash well.
Right now it is about 8" foward. Real ski boats have their pylon mounted close to the center of the boat, so moving it back might not be a good idea. What do you think? Brian

Re: 86 Starcraft SS 160

This afternoon, I cut the plywood for the casting deck. Now I need to deal with with some dents on the bow caused by the rubber stop on the winch stand. I'm pretty sure I can pop the the dents out easy enough. The problem is I need to reconfigure the winch stand so it dosen"t happen again.

Re: 86 Starcraft SS 160

Looks like you need one of these to stop that from happening after fixing it. Stoltz V Bow Stops - iboats

Re: 86 Starcraft SS 160

That's exactly what I need. Thanks Glen. When I bought the boat it hardly had a tongue weight. The bow bonced up and down on rough roads. I moved the axle back a couple inches. Now it pulls a lot smoother. I want to use the trailer some, and make sure I like before I restore it. Brian

 

[eddy622611]

Back in 2013 I fell at work and was laid up for awhile, nothing serious, just when I was healed I was behind at work and at home. Needless to say the boat project was moved to my barn and covered up. It is sitting right where I left it. I have been lurking on I-boats lately trying to get some motivation to start on it again.
I will take some photos and show everyone how it sits today.
Thanks, Brian

Welcome back, looking forward to the pics

Once again I am thinking of starting back on my Starcraft project. I work as a facilities manager at a summer camp. While I am still working making sure that we will be able to open whenever this pandemic passes and we can safely care for 800 children. It looks like I might possibly have a less hectic schedule for awhile. Fortunately I have another boat so we have been able to enjoy the water, but unfortunately That has removed the need to finish this project. Here are some photos of where it sits right now.
I had the engine completely rebuilt and every one and awhile I remove the spark plugs, squirt in some oil and turn it over. I have a lot of what I need to reassemble the boat with the exception of seats and a trailer. The original trailer needed some work and was kinda small. I figured it would better just to buy a new one, besides I’ve rebuilt boat trailers before and it ends up being a lot of work and if you count up all of your time it is probably less expensive to just buy one. That said hopefully trailer prices hasn’t gone up that much since I bought the last one.
