I decided that since I found wood rot and a cracked manifold on the
Marquis that maybe I should do a bit more investigating. Oh the engine
is fine, but I have noticed that the aluminum pillars which hold the
seats were loose on the floor. doing some investigating, the previous
owners had used large lag screws and had drilled small holes in the
plywood and ran the bolts in. Three of the five on one seat were loose
and when I pulled them out they were rusty which made the seat totally
unstable. Then I thought that I should get rid of the pillars and
build boxes for the seats, also providing storage room for tools,
spare prop, etc.

Then I got to thinking that those rusty bolts are indicators of
possible problems with the floor underneath. I have a very small
access to the steel fuel tank which is mounted under the floor and I
do have access to the sending unit as well as the anti-siphon valve,
but the rubber hose going to the fuel pump is getting cracks in it,
and I can't have that. So, my carpenter buddy and I are deciding to
rip out the floor and sides for a total re-do. I want to check to see
the validity of the fuel tank for rust etc. Plus add an extra fuel
tank for longer cruising range instead of strapping a spare tank onto
the swim platform as originally planned. This also gives a chance to
check out the stringers and investigate for other wood rot and replace
if necessary. I've already removed the back panel and the transom's
integrity is fine. No rot there.


Saturday I went to the a very reputable boat shop; the best in the
area- which is about 30 mi away, and was able to talk with a mechanic
who has worked there for about 20+ years. Yep, he's just about seen it
all. I told him about the cracked manifold which had been psuedo-
repaired with JB weld and he said to bring the manifold in and they
could inspect it, then weld it. I asked if it would hold, and they
said they've had boats out for better than 10 years with no failure to
their repairs, and it would be at a fraction of the cost of a new one
and they would also inspect the risers as well. But if the manifold
were too far gone (and there is that chance) they would install new
ones for about the same price as what I could get the parts from the
ebay stores and do it myself. I thought that was a pretty good deal.


I've removed the bent up bow railing which is of no concern to me.
While I was at the marina, I got a healthy can of marine epoxy which
they use, and will start in on filling holes where I pulled the
railing off and work on the nicks in the hull. when I'm done sanding
and prepping the necessary spots, I'll take it to them to apply gel
coat where necessary. I plan on getting rid of the antique depth
finder and the Ray Jefferson radio and update/replace anything else
that needs be while I have the boat stripped down.


I could go on about my project but Jimmy the carpenter and I are going
to lay out a floor plan and add conveniences to fit instead of just
throwing them in and tying them down.


Well, there will be no river trip for the wife and myself this year,
but- "duty now for the future."

need some ideas refitting a 23' Marquis 'cuddie'

Here's a pic of a boat just like it:
76Marquis922729.jpg


And it's runnable the way it is, but is shabby and needs some floor repair. So I figured while we had it all out, I'd like to outfit it with some cool creature comforts for the wife while we go river vacationing. like a sink and at leas a shower nozzle, I also have a 3000w power inverter to run a microwave. My carpenter has some ideas on making some space saving cabinets for various utilities .

What got me into this is that a friend of mine has a 17' camper trailer that he and his wife enjoy on a lot of summer weekends. I don't remember the name, I think it is an 'Easy-Go' but not sure. and when I stepped into it, I was literally amazed at how well it was designed with not a waste of space, and all plumbing and appliances were easily accessible. i couldn't believe how much stuff they put in so little of space. tiny sink and stove, which seemed Minature, but not inconvenient. the space planning was very impressive. So that gave me some ideas on what I'd like.

But I've looked around on the 'net to see if there were some pictures of some lay-out plans but I'm not having much luck.

Anybody know where I should look for ideas?

Thanks!

Define floor repair? Is it rotten?

Well, yes, and no. The stringers are ok, but sometime in the past a previous owner replaced a center sheet of plywood with ...plywood, and didn't do a great job of tacking it in. more or less a 'get by' job. then put some cheap carpet over it. It was soft and so we pulled the interior and took out the main of the floor to see if there was any damage undetected. nope all looked good and sounded well with a mallet. Now to do the floor right, and modify the original interior. I'd say this isn't a restoration more than it is a reformation project

Re: need some ideas refitting a 23' Marquis 'cuddie'

Had some old plywood getting soft in the center, and decided to re-do
the floor. when we pulled off the old carpet which was weathered
anyhow, we found out that in the times past someone had repaired the
floor by cutting out a center section and replacing it with standard
plywood. Evidently it had held for quite a while but it's days were
numbered. besides it gave us a chance to inspect the stringers and
other bracing etc.

So, after thinking about the re-floor, we decided to not go with
standard ply because it's not weather resistant, or marine due to the
expense, so we settled on "DRYPLY"

http://www.gp.com/build/product.aspx?pid=4882

A weather resistant plywood which has a lot of characteristics of
marine plywood but is more cost effective. Like $23.00 a 3/4 sheet at
Menards, and in stock too.

Regardless. It ought to last way longer than I'll ever have the boat.

Re: need some ideas refitting a 23' Marquis 'cuddie'

well, I'm back after quite a hiatus and seeing the weather will start to be warming up soon, My eyes are back at working on the Marquis. The floor is in, new fuel line installed while floor was out. extra cushioning foam added around the tank while we had it out... rotten wood has been replaced and glassed. I've added my 200a. battery divider, and am planning on using 1 engine battery, and 2 house batteries, and have the space lined out to do so.

Now, the boat has a rather large inboard fuel tank, but I'd like to add yet another (seeing I already have one) because getting out in the Ohio river fuel can be scarce between marinas, that is *if* the landing even sells gas, so I'd like to add another 12 gallon tank

It's a typical square red plastic Moeller Portable 12-Gallon tank

For weight distribution, I can put my batteries under a rear seat on either side of the engine and install the spare tank on the other. I'm sure thins has been done before, but... not by me. I was wondering if there are any special valves (electrical or mechanical) to switch from tank to tank that are to be used to be marine compliant. Or if there's any written safety restrictions concerning doing so?

Any help is greatly appreciated.

Thanks!

Tim

Ayuh,.... What motor,..?? What drive,..??

Weldin' manifolds rarely works out as planned...
Epoxy is probably the Better choice, short of replacin' it...

Gelcoat, which is a polyester resin, Don't stick to well to epoxy...

If yer usin' epoxy filler, consider Paintin' it after....

It's a 305 chevy (Mercruiser 228)

Seeing they're rally not that expensive due to aftermarket, I'd thought of replacing both manifolds with the updated kind. Y'know, more efficient better power, improved fuel economy etc, etc,

Ayuh,.... Goin' to center risers don't really offer None of that,... ya need the Kit, to match yer y-pipe...
'n ya might also need another t-stat housin' to match the changed water flows...

I'm not against yer Up-date, just lettin' ya know...

Re: need some ideas refitting a 23' Marquis 'cuddie'

I've thought about it both ways, and honestly I cant see that the center risers could be that vast of an improvement in power and economy. Sales propaganda? Maybe. But all in all, it would probably be best to go back with what was supplied by original OE
