1988 Maxum 1700...There's no turning back now!

Re: 1988 Maxum 1700...There's no turning back now!

For the first time ever, I'm jealous of all you warm weather folk lol. Normally I'm all into the changing of the seasons and the incoming winter, this year ummm no... I'd love to be installing my transom and stringers and glassing right now. Oh well.
Anyway, I've ordered the vinyl for the interior and got my friends sewing machine all set up. Just doing some prior planning. Any suggestions on how I should hang/attach the gunwale pieces to the gunwales. The originals were screwed through the wood into the gunwales and then wrapped with the foam and fabric and stapled underneath. I'd like to get the pieces all wrapped and just attach or hang them somehow. What have others used/done?

Hey all,
So I'm in the process of re-doing the upholstery and removing all the old stuff from it's wood backers. Trying to keep everything together so I can use the old as templates.


I'll be replacing all the wood over the next week or two with 1/2" exterior. Any recommendations on what to coat the wood with? The original looks like it was painted with something and I'm thinking I'll do the same just not sure with what would be best. Any suggestions? Here's some more pics

Hey neighbor....Ive seen some with just primer/paint, some coated with resin or polyurethane...mine were either just painted or left bare ...and they dryrotted...when I do them over, im coating the wood with resin.

Re: 1988 Maxum 1700...There's no turning back now!

Yeah was thinking resin as well but not sure if that's overkill since these pieces won't really be exposed to moisture/weather all that much but I guess since I'm doin it, I should overkill it :laugh:.

After 25 years, the originals aren't in all that bad - i'd expect worse but it does look like they were painted on all sides including edges - some areas though where the paint wore, have dry rotted.

Thanks zool

I used copper-green treatment on the wood for my upholstery. It is supposed to keep it from rotting. Like further, my original wood seemed to be just treated ply and was still in pretty good shape after 25 years, so I did not go through the trouble of resin/glass.

I'll check that out... Thanks SD

I reviewed my 22 foot bayliner restoration plans; my decision was to use oil based deck stain and finishing system. The research I did back then led me to believe that this is my best option for water and moisture protection for this specific application. According to the experts here on this forum and based on what I experienced during demolition, I believe that poly resin without glass is useless. There was also the epoxy route but this was overkill for this job. Knowing myself, I might end up overkill it when I get to this step but for now, it is marked as “Oil based deck stain”

For the seat's plywood backers only ^^^^ Correct?

Re: 1988 Maxum 1700...There's no turning back now!

Yea JB, I was asking about the plywood backers only and I think that's what DeepBlue is referring to after reading it over.

Thanks DeepBlue, I'm looking for just waterproofing properties, not structural. I think poly resin without glass does have fine waterproofing properties just not structural. I may be wrong here though. I'm also looking at cost so if its cheaper and as effective to use the oil based deck stain I may go that way. Also I'm doing this in my basement now (don't have a garage and its getting cold out) so I need to figure out something that won't stink up the house and p off the admiral... at the same time.

Re: 1988 Maxum 1700...There's no turning back now!

Poly resin, even in 'non-structural' applications is likely to crack over time. And the glass hull moving a bit & people sitting in the seats probably does impart movement to the panels, if only slightly.

I'd use a good oil based penetrating stain, applied heavy & wet w/ a rag (to maximize amount that's absorbed), wipe it off, let it dry and apply a good spar urethane (2-3 coats per side, & the edges w/ every coat so they'll get twice as many coats) if I had to work in the basement. The fumes shouldn't be too overwhelming if you don't do all of the pieces at once. And it off gases fairly quick. Compared to the offensive smell of poly resin or the long cure time for epoxy anyway.

I wouldn't do the work in the same area as a gas furnace or hot water heater though :watermelon: No reason to make the Darwin Awards for 2013...

Re: 1988 Maxum 1700...There's no turning back now!

Thanks JB... Make sense. I'll follow what you recommend. :lol: I'll be working in a separate room from the water heater and furnace for sure.

Re: 1988 Maxum 1700...There's no turning back now!

JP, yes, my comment was aregarding the seat backers and - in my case - the upholstered panels on the sides of the boat.

Further, I disagree with you on this one. Poly resin by itself is not a good water and moisture protection technique. The reason is that poly resin without glass is very weak and brittle; any frequent and systematic pressure on plywood coated only with resin (such as walking on it if it is a deck or sitting on it if it is a chair, etc) will cause this resin to – over time – crack and allow water and moisture to seep in.

Now, I am not saying poly resin with no glass has no water/moisture protection characteristics, I just believe it is a poor option for that matter and it is not going to last.

Epoxy resin is a different story though

Re: 1988 Maxum 1700...There's no turning back now!

Yep got it. I am definitely new to resin and its properties, but learning everyday. Thanks DeepBlue. I was worried about using resin in the basement anyway due to its nasty fumes.

DB is 100% correct about Poly and Epoxy. For Waterproof coating Epoxy is the way to go Poly by itself is no good for the reasons he stated. If you want you could use the old stand by of Boiled Linseed oil, thinned with 50% mineral Spirits and 30% Polyurethane. This will penetrate the wood and seal it very well. Let it set for 30 mins and wipe of the excess then dry for 24 hours. Then paint with a good oil base paint. It'll last for years on non-structural components.

Re: 1988 Maxum 1700...There's no turning back now!

Thanks Wood! Yes now I understand and will go with oil based stain and spar urethane or your boiled linseed oil application. I recall now Zool's using epoxy i believe that's why he suggested that on his application.
Thanks again guys

Yea, Im using epoxy throughout the build, I prolly should have clarified that. Ive coated so much wood so far, it feels like a second job to me ....most of the backer wood i got is for the combing pads around the cockpit..where water can slide between the gunnel and the backer board.

Re: 1988 Maxum 1700...There's no turning back now!

Ah man, look what I did.... You know when something just presents itself and you just can't pass it up, well this was
one of those.... 1996 Chris Craft Concept 18. She's mine now... I guess I'm changing my resto plans now. She's in good shape... One owner and appears to have been covered/maintained well... 4.3 volvo and in solid shape, had my buddies marine surveyor check her out today and gave me the green flag. She's solid and motor purrrs, only 200 hours. Needs some minor stuff and will need to do the bellows and prob the gimbal bearing while I'm at it in the spring along with other minor stuff to make sure the motors all good - gonna spend some time reading up on these motors and head over to the volvo forum as I'm clueless when it comes to these motors.
Needs a good cleaning all around, sun pad needs to be rebuilt (woods backer is rotted) all other vinyl is in great shape, new bilge blower, needs stereo changed out, etc. Minor stuff
Haven't seen alot of restos on these.... Hopefully that means they're built well?

Here's a pic


Picking it up next weekend and will start going through it and will post more pics then - will most likely start a new thread!

Re: 1988 Maxum 1700...There's no turning back now!

If the sunpad's worked & needs to be replaced, I'd be surprised that's all. Hopefully.

If the bellows need to be replaced, that lets water below deck or at least thru the motor's keyhole.

Hopefully it's as good as it's portrayed, I like long tapered open bow & slanted back windshields on this type of boat.
