Well, somehow this old girl kinda just landed in my lap. Think I'll keep it but where to start is the question.

Start what? A total gut & refit?

How do you plan to use it once you rehab it?

Does the I/O driveline work 100%?

Congrats on having a lap big enough to let the big ole girl land on it.....

Re: '87 Islander 221 Restoration

Well I think I want to totally rehab the whole thing. Everything i there as far as I can see. The motor runs well with the compression within 14 psi on all four and the lower unit was full of oil with no water as far as i could see. The floors are junk as well as the transom but not too worried about that. I've seen it done on this site quite a few times and as far as i can tell the folks on this forum are great when it comes to advise so I think its time to start the tear down! You agree?

Re: '87 Islander 221 Restoration

You agree?

Agreed!:thumb:

Yup, I think the first spot to start is to give the driveline a thorough check to be sure everything is aok, good to go. Sounds like you've already done that, so, next step is to pull it out. Then, pull everything else out!

A great spot to get your bearings on these kinds of projects is the "Starcraft Rebuilds" thread - you can find that right in my signature there.

You found a great spot to be here on iboats MT, well done!

Welcome to the drydock and welcome to the Starcraft brohood:welcome:

Re: '87 Islander 221 Restoration

Ok so I found that the extent of the rot is close to 100 percent of the floor and transom. Not to worry though, I was expecting that when I started this. The engine was properly winterized and and I found the paperwork to prove it so that makes me feel a little bit better. I pulled up some of the floor above the center mounted fuel tank and I cant believe how dirty it is under there. Also, I wonder how big the fuel tank is? It's huge, about ten inches deep, twenty wide or so and all of three feet long! Guess I'll have to replace all of the foam too. I wonder if the big cans of expanding foam an menards is the same as whats in there? Anyway, saturday the engine and drive will be out and hopefully most of the floor, I'll get some pictures for you guys. Oh, it will be used mostly for fishing some of the bigger lakes around southwest Michigan including the big one so I think I would like to finish the floor with epoxy paint with silica sand for traction. Any thoughts?

Re: '87 Islander 221 Restoration

Not aerosole spray foam. There are a few good choices, spray foam isn't 1 of them.

Go thru a few of the rebuild threads in Jas' link he referenced earlier, lots of good tin boat building tips.

Re: '87 Islander 221 Restoration

Ok, gotcha, no spray foam. Yeah, ive got quite a lot of work ahead but I'm not worried. I have wanted this for a long time so I'm willing to do everything I need too. Sooo looking forward to this project and all that goes with it. I plan on using this boat for fishing and a lot of cruising with the family but I still want a nice clean interior that is not carpeted so its easy to clean the fish guts out. I used an epoxy paint with silica sand on my bowfishing boat about three years ago and it is tuff stuff. Never gets covered in the winter and not a scratch or peel in it anywhere.
Anyway thanks for the info and I'll be putting up more pics this weekend, thanks!

Re: '87 Islander 221 Restoration


Well, got a little bit done. took the engine out, lower unit is off, and some of the foam out. I'm glad to see its got a big fuel tank which is fifty-two gallons. Hopefully going to get the old transom out today if I can figure out the wiring back there. wish me luck!

Re: '87 Islander 221 Restoration

Motor Tech,

You have a nice boat there. I have been working on getting my old Starcraft in the water also. I just did the transom. These projects are a lot of work to say the least. However, it should be worth it. One thing is for sure, you will learn a ton. I don't know much, but already a lot more than some of the non DIY boat owners. I hate running into frustrating hurdles; but it seems there is always a decent solution, you just have to have patience, and ask the right questions. There is as ton of info, experience, and knowledge on these forums. Good luck and have fun.

I tried to take lots of pictures with the digital camera before taking things apart. It is nice to see how it was; especially after long breaks between work.

Re: '87 Islander 221 Restoration

Welcome to the Tin Drydock, MT. You got a good start on the demo work. They get loaded with all kinds of stuff under the deck. Watch out for rusty fish hooks. Is the foam dry or wet? Jason just tried some Behr deck treatment, the name escapes me, and he likes it. I just looked at it in Home Depot and think I'm going to try it too.

Just remembered - Behr Deckover.

Re: '87 Islander 221 Restoration

Well GA Boater, yes the foam was wet and the mice have made it into a cool little maze that smells of a high school locker room urinal. I guess they liked nuts too, cause there are hundreds of shells underneath the floor. So, does anyone know how far one gallon of pour in foam will go? Also, is the two pound can of Gluvit enough for a twenty two footer? I can't believe how much those two items cost but I'm willing to pay for the peace of mind they both bring. I also went to the mall trying to find an inexpensive digital camera so I can take better pics for you guys but then I realized money spent on a camera is money NOT spent on the boat so sorry for the poor quality pics. Talk at you later!

Re: '87 Islander 221 Restoration

I think the 2lb Gluvit is not going to be enough, only covers 25-35 SqFt. Coat-it hasn't been used nearly as much, but has been used.

You're working the wrong way w/ the foam calcs. You need to estimate the weight of your boat & motor, plus any gear/equipment/stuff that won't float free if things go wrong.

That weight divided by 60 (the amount of weight a fully expanded 2lb kit will float) is the # of 2lb foam units you need to 'float your boat'.

Ex: 1500lbs of boat/gear & etc

1500/60 = 25
You need 25 units of 2lb foam to float a 1500lb boat

That's 3 16lb kits (8cubic ft each) and 1 4lb kit (2cu ft each) which runs @ $224 + shipping. Total of 20lbs of foam, total of 26cu ft, which would float 1560lbs...

For $40+/- & a bit more shipping you'd get an 80lb kit (40cu ft each) which in theory would float 2400lb of boat & etc.

Those figures are all based on maximum expansion in ideal conditions, w/ little waste, which may be more then a little......

[SIZE=+1]2 LB [/SIZE]Density Urethane Foam (U.S. Coast Guard Compliant Marine Foam)
[SIZE=-2]Common Applications: Our 2LB density marine foam is recommended for void filling in nonstructural applications. This product can be poured underneath decks and inside cavities where a lightweight flotation foam is needed to provide buoyancy. This foam has been tested in accordance with U.S. Coast Guard Regulation # 33 CFR 183.114 . This foam is approximately 95-98% closed cell which resists absorbing water, however continuous water submersion can eventually lead to loss of buoyancy over a period of years. We recommend this product strictly for flotation applications. If looking for a liquid foam for sculpting or casting we recommend using at minimum our 3LB or 4LB density. More questions?

Sheet foam from HD/Lowes may be less expensive, float load calcs are less accurate & it fills less volume.

There are other advantages to the sheet foam. Pros & cons for the expanding foam

Re: '87 Islander 221 Restoration


Well, sometimes you just have to wonder what people were thinking. This guy replaced parts of the transom with treated 2x12 and pieces of 2x4. What a mess. Oh well gotta keep moving. jbcurt00, thankyou for the wonderfull information on the pour in foam that will help greatly.

Re: '87 Islander 221 Restoration

You just never know what is hidden. And the strange ideas for "safe" repair. :facepalm: Keep at it, MT. That is light at the end of the tunnel or you're looking through the transom keyhole.

 

[Motor Tech]

Re: '87 Islander 221 Restoration

Ok guys, just a few questions to bother you with. I have the transom wood removed and found 3 little pinholes in the aluminium. they are so small that I think the gluvit would be good enough to seal them up. The question is, after I clean the aluminum should I use the gluvit first then prime the whole thing or should I prime it then use the gluvit? Another question I have is do you think I should prime the inside of the aluminum between the wood and aluminum? I want to at least get the transome done before the cold weather hits and I lose the ability to paint and seal everything up. I will only be able to move the boat inside on the weekends in the cold months so I plan on doing the electrical and mechanical things during the winter then when things warm up I will finish the floors and cuddy then.

Re: '87 Islander 221 Restoration

I'd prolly not go with Gluvit for that application, it likes gravity too much.

I'd get all the corrosion off, skim coat with JB Weld, prime, paint, drop in the transom.

Cheers!

Re: '87 Islander 221 Restoration

Thanks Jason, I didnt know how runny the gluvit is I take it its pretty thin? Ive used JB weld before, cant tell you why I didn't think of it. Duh! Thanks again!

 

[GA_Boater]

Re: '87 Islander 221 Restoration

The other thing is you will mix up far more Gluvit than you need for 3 small holes. Save it for the rivets and seams. Jason's JBWeld idea is best.

 

[jasoutside]

Re: '87 Islander 221 Restoration

Yah, Gluvit is about like the consistency of pancake syrup. But I'm warning you man! You have any left over, DON'T dunk yur morning cakes in it! That's a rough way to start the day!
