I have just purchased a 19-foot 1988 Invader for use at our lake house on upper Lake Champlain. I think it may be a V198 model, although it came with absolutely no paperwork other than a title and a foreign-language manual for the motor (yeah, that's not much help!). It has a Volvo Penta A131D motor and a Volvo 275 outdrive. It's in pretty good shape, having been mostly garaged by all the previous owners... the sole is solid, original upholstery has very little fading, cracking or physical damage, and it runs reasonably well. It does need a carburetor rebuild (accelerator pump diaphragm seems to be bad - sputters on initial rev-up) and a rebuild or replacement of the seawater pump (leaking), but is otherwise not in need of any obvious repairs. I've restored and maintained other sailboats, some with outboards, but a pure I/O power boat is new to me.
I have a couple of questions that I'm hoping you all can maybe help with...

I have a couple of questions that I'm hoping you all can maybe help with...
- First, are there any ways to identify the actual model of this boat? I've searched online for data and photos, but there's not much that clearly identifies models. Any Invader experts in the house?
- Second, are there any online sources for brochures, information, owner's manuals or workshop manuals for these boats? I didn't find much except parts manuals for the Penta. I did find (and ordered) a Seloc workshop manual for the Penta, but I'd really like to find an original operator's manual and some brochures about the boat showing what it looked like originally.
- Third, I'm not sure if I want to just enjoy the boat as-is, or if I want to spend the time and money to restore this boat to its original glory. That question hinges on how much the boat is really worth. Are these boats now considered 'classics' which might be appreciating in value? Most of the ones I found online were, sadly, in a really poor state of repair. So... I'd appreciate your wisdom... is this worth restoring?
- Finally, there are decals on the console which show buoys, lights, etc. - I know they're hokey, but if I do restore the boat I'd like to replaced these faded decals to preserve the originality. Is there any source for such things?
