Here I go again!!!

[Capt. Bob]

Lookin' good Lewis    but...

You may want to cock your head when reading the MPH gauge.

[slvrlng]

Damn Bob, they are still in the box and the cage was loose. Of course in Ga. we always kind of have a different kind of view .

[seabob4]

Well, Bob, I think the, oh, shall we say 3 degree "list" of the speedo in the box will produce 80 MPH ON THE WATER!!!

Just had to give you some there...

[slvrlng]

Yeah its amazing what a set of Boyensen's can do for performance! :joker:

[Capt. Bob]

Lewis,
Are you also going to re-power?
Did I miss something  

[slvrlng]

No repower yet but just planning for the future. Seabob will be rewiring mine when I get to that point and has had some great info and help. What a cool thing to have people with so much knowledge available for help as I am clueless when it comes to wiring. One thing, since I don't need the oil pressure guage anybody that needs one PM me and you can have it cheap. You can see these guages look great and not that I need them yet when I see a deal I went for them! After looking at Faria's site there are quite a few motors that use the 12 pulse setup so these should work with just about anything I do in the future

Lewis,
Obviously, as we talked last night, the tach will work with your Johnson (man, I can hear all the comments coming on that one... :silent: ).

So do you want my "System Check" gauge?  It's just sitting around doing nothing...

So today I finally started cutting out the floor.  If anybody has a hull of this vintage and you have some soft spots and have not replaced it yet I figured out why they get soft. When mine was built they started with 5/8 marine ply, then glassed a layer of mat on the bottom. They then attached pieces of uncoated ply strips about 2" by 18" to the underside with phillips head screws, then tightened them down with nuts on the bottom. Then the floor was laid on the stringers and bedded down with the "concrete" stuff. Once the floor was down they laid glass down to about a 3/16" thickness on top and pressed the diamond pattern into the last coat of gel.
The problem starts when over time these screws flex and crack the gel above them. Water then seeps in and over time you get rot and delamination. Each of the screwheads today had a small circle of loose gel and glass just sitting on top of it. The strips of ply were placed on the bottom of the floor I would think as stiffeners. I don't think they were placed there as backing plates because you can't see where the screws are. Sooooo, what do you think?

Here is where I started cutting.
 

Wherever there were no screws the plywood is in really good shape.Doesn't matter its all coming out!


Looking down the side of the stringer which so far is really solid. In the picture is also one of three bulkheads that I can see so far these run out to the chine.


One of the screws that caused the problem. Remember these are hidden under the glass on the top of the deck.


Check out how much "concrete" stuff they used to glue the deck down. It literally ran down the sides of the stringers and puddled up at the bottom.


One of the strips bolted to the underside of the deck. You can see how its not coated.

Good to see you taking the plunge, so to speak, Lewis.  Feels good doesn't it.  I'm sure I'll learn as you progress.

[Skoot]

 right on bro, glad to see you got started.  She's gonna be awesome

Rainy day in the ATL today! After I left the boat yesterday I realized I had not jacked the trailer up so it would drain. I was worried after 1 1/2 inches today and more to come tonight so I stopped by to check on it. I didn't bring a ladder today, but who needs a ladder when you have a truck! I thought you Florida guys might enjoy some fall color, so here ya go.

Hmm... looking at that screw, you'd think that problem could have been avoided if they had just used a countersink screw- the head would have seated slightly below the surface of the wood which contacts the underside of the floor and probably wouldn't have rubbed.  I have a theory about why they used that particular oval/pan head-

Whenever I was redoing some things (namely removing the rubrail) on my 19-6, I came across a smorgasbord of all different kinds of sheet metal screws with different heads and different drives and lengths.  One thing I noticed with all the original countersink screws I removed was that they were ALL slotted drive.  The oval heads (both machine thread and sheet metal thread) I removed were kinda 50-50 philips or slotted.  Anyone who's screwed a screw knows a slotted drive is a royal PITA to work with when you don't have controlled tooling.

I don't know if AS was using a bargain bin of mismatch fasteners back then or what, but if they were, they got screwed (pun intended) on the countersink fasteners.  I bet that in the redundancy of building boats, the workers simply got tired of fighting with the slotted drive countersink screws that seemed to be available and used a pan/oval head philips in its place, especially in an area where it would never be seen.

As far as the through-bolted planks you came across; I agree with your thinking about their purpose being to add rigidity to the floor.  The fact that they didn't "seal" them with a conventional method (wrapped in glass) is understandable because if you'd never had an unforeseen water intrusion issue most likely caused by those screws you pointed out, they'd probably still be dry because, effectively, they're already sealed where they are.

This is just my theory, if someone disagrees, please feel free to say so  

In any case, water intrusion in a boat, especially in one as old as ours is, is almost inevitable.  Even the best sealant you can buy gets brittle over time and wallows out a hole right along with the screw- that coupled with every mans nature to hastily and excitedly customize a boat at times.

Anyway, its good to see you making some progress on her.  Have fun and git'r'done.  8)
