Hello, iboaters!

I,ve been a reader here for years.Iboats must be the #1 goto site for anyone looking for boat restoration advice, the knowledge her is just overwhelming.

I'll start by giving a little history. I bought the boat in 2006, it had a little weathering and a springy spot in the floor. The carpet was loose at the gunnels. She didnt leak at the time. If the floor got wet over a weekend fishing trip, that spring in the floor would soften until it dried out again. I moved in the fall of 09 and upon doing so, i stored the boat at my parents. Long story short, red squirrels moved in and just about destoyred everything. They chewed through my main wiring harness, tunneled through foam, made 3ft balls of squirrel nest from carpet and carried what must have been almost 2 bushels of walnuts in the boat. The walnuts still had green husk on when they brought them in, so that all turned to mush and stained everything. The cover ripped that winter allowing melting snow and rain in which didnt help. they destroyed a stereo while as well. Livewell drain line was chewed under the deck. Found that the hard way.

After giving everthing a quick patch job i only use it about 3 times a year due too trust issues. I was amazed at how wet the foam was while tearing it out. Except for the 3 or so trips per year, it has been in my polebarn since 10. I had my suspicions of waterlogged foam as the boat felt heavy and didnt handle the same.. This stuff will not dry out once waterlogged!
Here's a few pics of the tear down and what i,m finding. I would have been at the assembly stage here by now if i hadnt found corrosion under areas of the wet foam. I,m kind of stumped as to what to do with this. I did find my major leak, about 10 rivets alnog the keel. As loose as they are i dont trust replacing them with the same size 3/16. So I,ve purchased 1/4" solid rivets from jay_cees for replacement.
Seems like pouring in new foam wouldnt be a good idea unless I first address this corrosion issue by some type of treatment. The best info i have found is aluma prep and alodine or what it known as chromatic acid. Sounds like some bad stuff to work with. I have gluvit for seams and rivets. Marine tex gray epoxy for the pits.Does anyone have advice on how to tackle this corrosion?

Didnt take alot of pics.




Tearing out the foam. That was bigger job than i expected.


Again, everything is stained from black walnut ooze.

i think the lighting may has enhanced the affects, but look at what walnuts do to a boat!


Leak testing.


And the leak!


Sources of leak, about ten of them.

Your corrosion issues are from trapped water causing galvanic corrosion, the tannic acid from the walnut hulls probably didn't help either. A stainless steel wire cup brush in a grinder or drill will make short work of it. Pressure wash after wire brushing, skim the pitting with the marine tek, apply gluvit per manufacturers instructions, and then paint the inside of the hull with a self etching primer. Check your transom, it's probably toast with corrosion between the wood and the aluminum hull.

After you get everything straightened out and you want to make her pretty again, you may want to consider installing vinyl deck covering like I did in my Tracker:

Thanks for the reply, jigngrub! I checked out your link. you do great work! My plan has been vinyl for the deck itself, but i think the rounded side panels would be above my skill level for vinyl. lol

The transom was wet near the foam and in the through holes for engine mounting. I havent pulled it yet due to fears of damaging something from lack of support. These boats get flimsy quick with panels removed.

On the corrosion. Forgot to mention any aluminum in contact with PW has white surface corrosion. The advice you offered was my plan and what i got that from reading all you guys post. Should I treat the pits before filling with epoxy and the hull before hitting it with etching primer? Maybe a cleaner or white vinegar?

Go ahead and yank the transom wood. SC didn't build the hull around the wood, all the wood was added after the hull was complete.

That way you can take care of any more corrosion. The white vinegar won't hurt anything, just give it a good pressure wash and good dry out before using any epoxy.

Just realized my title didnt take the "190"' had connection issues when I made the thread. No biggy, just wanted to keep it separate from Budskis thread.

Ok fellas, I pulled the transom and dont like what i found. Gotta tell ya I wasn't expecting this. The wood was still moist against the aluminum' but the wood is not really rotten. I had some electrical issues after those nut eating red devils had their way with my boat.:mad-new: The battery kept going dead and at times my FF/chartplotter would come on for no reason. The other issue was a livewell pump would randomly kick on at half power. Last time it happened i yanked and taped the wires as it seemed to have nothing to do with the switch panel. That stopped the battery drain. I cant help but wonder if those electrical problems added to this corrosion.

Aluminum side of the transom or the rear.


Front side.


Corrsion appears to be confined to areas around fasteners. Not sure if it was just from moisture as you can see the corrosion in the high and dry areas as well' but always near the fasteners.


I gave one spot a brushing just to see what I,m dealing with.:facepalm:


I found one of these on each side.:facepalm: I.m sure there will be more before im done. I just dont know what to do with these. Will epoxy (marine tek) be a good repair on a transom skin?


Thats light shining through outside transom paint where I brushed the inside.

The transom had the same PW as the rear casting deck, only doubled. I dont think SC used treated, looks like marine PW. Unless marine PW was treated back then?

Hey Will, looks like a good project to follow along. I love the nice wide gunwales on those boats and I'm trying to come up with a plan to incorporate those on my Crestliner Superhawk that i'm refurbishing. When you add back the foam make sure you allow for drainage of all compartments. You can check my thread and see what I did in some of those areas to accomplish this. Good luck with the project.

Thanks 83mulligan, I will surely check out your thread. I am concerned with drainage of each foam compartment and especially the rear of each chine. Still trying to figure out what to do as far as treating and coating the aluminum. IdealIy moisture shouldn't be a future problem, but it is a boat. I get an occasional shower from wind and waves or a rain shower. My greatest concern is to get this corrosion as close to neutral as possible and the best protection. Has anyone had experience with a product from Dupont, I believe the products name is Variprime?

I hate to say it, but the Superfisherman will be put on hold for just a bit. A man has got to fish.

After finding that corrosion, I decided to look around for something that might get us through summer tubing and fishing. Well, I found something.She's not the prettiest, but it's a Starcraft and it runs. How well it runs I dont know yet, as I need to get the old gas out of the tank before running it anymore. Has an 1776 or 77 85 HP Evinrude v4. The transom has a little punk, but it will easily get through the summer. The trailer fenders look rough,overall the trailer is very solid, it would paint up nicely. Oh, the boat is a 1977 18' 4'' holiday. The boat has a 20 gallon mounted under the splash well, it also came with a 5 gallon reserve can and a selector switch for swithing tanks. Came with and extra prop that has a chip missing from one blade. Got it all for a few c notes south of the k mark. I will be back to finish out my Superfisherman later in the year.
Thought would share some pics. I've only taken one pic, the rest are from sellers ad.
The ride home.

Out of the frying pan and into the fire with an even older SC holly in original condition. :lol:

That little bit of corrosion you have going on is nothing big at all, you should check out the SC forum and some of what we've had to repair. :eek:

No this isn't the crab nebula, it's the transom of my Chief.

HOLY SWISS CHEESE!!!!
Yeah, this old holiday could grow on me. The deal with my wife was, i,m supposed to sell it to my bro-inlaw or one of our fishing partners at seasons end. This holly has the potential to get me banished to the doghouse.:facepalm:

I might be over thinking the corrosion correction and I have found my way to the hidden starcraft forum. lol You guys are awesome, very good at documenting.!!! Lots of good reading in there for sure. I will get the SFM back on the water.

Hey you could always PM a mod like GA_Boater who posted above and ask him to move your thread over to the SC forum if you want to.

Shh.......... secret forum, secret files...............

Yep, all ya gotta do is ask for it to be moved :cool:

Be sure you're up to date on your MBS vaccine if you ask to have this topic moved to the Starcraft forum. ;)

The strain found there is especially virulent :eek:

Gentlemen, we have a problem. That Starcraft strain of MBS has jumped the thread barrier.

Right now I,m working on adding some rigging to this old holiday without filling her full of holes. If all goes well, we should be splashing around in lake Huron a week or so from now. I have no problem moving this over to the starcraft forum, but a warning, I might be a little slow until later this year.The reading and projects over there are almost overwhelming.
