First Time Restoration

[DSMSpence]

Hey there!

I was thrilled to find this forum. I’ve grown up on Cobalts had at least one my whole life. My dad’s current boat is a ‘94 200 and it’s a total gem. Prior to that, my family had an 87 and a 76. The 76 model was a 20 footer that I grew up on and I swear that boat got into my blood. I’ve always loved the 70’s Cobalts and vowed to own one someday.

Fast forward to now and there are two 70’s era Cobalt 18 foot trihulls for sale in my city. They’re both in fairly tough shape and I haven’t had a chance to inspect either in person yet. I’d love to live out my fantasy of restoring one of these vintage boats, but I want to be aware of the issues to look out for. Like I said, I’m no stranger to boats and the expensive surprises they can occasionally bring. But I’m curious if anyone else who’s been through the restoration process has some tips?

My plan would be to tackle all cosmetic work myself and have a mechanic work on the engine and lower unit. Not seeing the boats in person or knowing their service history obviously makes those costs pretty unpredictable, and I’m aware of that.

But in terms of the restoration process, are there other areas that I need to be aware of? For example, does this generation of boats have any electrical gremlins? I guess I’m freely admitting that I don’t know what I don’t know and would love some guidance from anyone with experience.

Thanks!

Hey DSMSpence. Welcome to the Cobaltchat forum. So glad you found us!

In terms of structure I would make sure that any wood in the boat, particularly transom and stringers, are not rotted. There is a youtube vid of a guy who was looking to do the same with a Sea Ray and got more than he bargained for.

Others will chime in shortly.

Be sure to document with pictures.

Again welcome aboard mate!

I don’t have much to add but a hearty welcome!

I’ve got an ‘87 DV18 that I’m going through — I bought it last July (2019) and I got it on the water once in the time since. I had some tasks that needed attention — minor in my eyes — issues with a thermostat, I fried the alternator by accident, some wiring areas need attention (breakers not working). I’m just wrapping up some interior work — doing my first ever upholstery job.. I’m barely into it yet though. I’ve done a few side panels and know what’s involved there. I’ve switched out the throttle/driveline controller and am hoping to wrap that up in the next day or two so I can get it in the water again.

Like Aslan mentioned — walk in the boat and see how spongy the floor is — that will probably give you a pretty good indication of what’s hiding beneath — pull up the floor if possible to see what can be seen. These boats, though made much better than cheaper brands, are not immune to rot if not taken care of properly. What I can tell you is that the wiring is pretty simple in my boat — there’s just not tons of it.. Sure you may have to chase a wire from one end to the other but its pretty easy and I can only imagine that a ‘76 would be even easier as it’s probably got less stuff on the dash to wire up — but I’ve never seen a ‘76 so what do I know???

I’ve got very little experience with the mechanicals of these boats so far.. The engine in a nutshell is pretty straightforward but has some marine tweaks on it — the stern drive is a foreign area for me — I’ve yet to do anything on mine as it had a pretty thorough going-thru by the previous owner by a local shop.

If you go to check out one or both of these boats, take lots of pictures, poke and prod what you can and feel that floor with your weight and post questions and pictures here. I’m sure others will chime in with their concerns and thoughts for you.. There are a good group of people here that have a wealth of experience!

I don’t want to rain on your parade but you need to be aware of what you are undertaking. My experience talking here.

First, you must have an emotional attachment to the project otherwise you will never complete it. Sounds like you may check this box.

Do you have the room to dismantle a boat and have it occupy that space long term. Will your wife want her garage back

Start with the best boat you can afford.

Don’t take it for a ride once it is worthy. You could end up (like me) with a running driving unfinished project.

Figured out a budget? Probably should double it. And don’t plan on ever getting it back.

If I haven’t scared you by now, have fun with it and be patient.

From experience....I would say double the budget and triple the time you think it will take.
