it was apart when i got it, Allen had built a cradle for it to sit on.
before i set the stringers i fit the top (several times actually) and pulled it together front to back with straps, i even over compensated some.
that prob explains the gaps, but i guess i should have pulled from the rear corners.
im thinking leaving the gasket out at the nose and rear corners (where its really tight) and maybe extra gasket or caulk along the back.
what has anyone else done for the part from the back to the transom (where the trim piece goes)
i think someone mentioned glass on the inside on one thread.

Joe, I just had an "aggravation flashback looking at your pics.  (AKA = been there, cussed at that!)  I had to pull the deck back off, move it forward to minimize the gap at the stern, and then set it back on.  (It wouldn't "slide" forward with the sealing tape in the joint.)  Since I was more concerned about getting the gap tight at the stern, I started there when mating the halves together and worked my way to the bow.

I considered "glassing" the seam from the inside, but decided against it when I saw how little room there is to work up under there!  (Especially back at the stern, which was my biggest area of concern.)  With the sealing tape and a bead of 3M 5200 all the way around, it turned out water tight and no problems so far.  I did come back inside and run another bead of sealant around the lip of the joint from the inside once the halves were married back together, probably over-kill but that's how I felt best.

Sorry I didn't get any pics of the process, but working alone with sealant all over your gloves is not the time to handle the camera.  Take your time, you're doing great.  This was a major milestone in the project, hard on the back and frustrating at times, but worth the extra effort.   ;)

I'd forgotten this is was Greens other project boat. 

I'm kinda with Mark on this one, maybe working it together from the stern forward is the way to go and it'll all pull together as you attach them.

Seems like a good plan!

I had the same issue ... I dropped and set the top half maybe 6 or 8 times before it was ready to be screwed in place.  Seemed that I could never get the back to line up while it fit like a glove everywhere else.  So ... the final drop, I set the stern down first.  I could lower it on a rope pulley and position it with one hand while the other gave slack or tightened up the rope.  Once the rear was in place and secure, I lowered the front almost all the way - set a pair of screws on each side of the rear, then dropped the front all the way.  Putting the rub rail on, I started at the back and worked myself forward.  I had wide-head stainless screws that really pulled the two pieces together snug - all the way until the "bend" approaching the bow.  Underneath the bow cap, my top half is protruding a full 5/8's to 3/4 inch.  All along the sides and rear, though, I've got full contact and am water tight.  For me, I figure that I will rarely, if ever, see water approaching the rubrail at the bow - perhaps on the downwards slope of some really big chop or wake - MAYBE - ... and even if I did, I probably wouldn't see any more water that I'd get in the boat dripping off our swimsuits and such.

well worked on this baby all weekend...
rub rails polished, helps when you know what yer doing  :o i'll be ready next time
gas filler and vent installed
top mated to bottom and screwed together  :P, now that was quite a job
i used foam tape made to seal toppers, and lubed it and the top with KY... of all things
glassed in the splash well, 3 layers of biax
i have 2 questions here
1 is 3 layers enough ?, the original cap had about 1/4" of layered glass plus filler.
2 is it acceptable to use plastic body filler to feather in the new glass (this boat is painted) , or do i need to use dura glass or something like that ?
i wanted to get the dash drilled out to fit the new gauges, figured i should install the helm and wheel...
it had a mores rack but the cable was vary stiff, cant get them apart to lube (guess yer not spose t do that anyways)
so at the risk of mock and ridicule i fess up, i had a teleflex rotary helm with a 16' cable from one of the V8 donors so i ran the cable in from the other side and have a loop under the bow. i kno, but im running out of money here so save $120 for now.

I have a rack helm & 11 foot steering cable from my CV if you would like to try that ...
Little sloppy but no binding or sticking.
Worked great on the CV up to about 50 mph.

Thanks Gregg
after installing the rotary helm with the 20 degree tilt on it i think i like that.
stopped at hannays today, picked up a new bezel for the helm and 2 more gauges, cant have to many gauges  ;D
is the 11' measurement the conduit length ?

Think you just measure the cable ... so yes ...
We put an 11 foot one next to my old one and said " Looks Good " ...

" the cable i took out was 10' "
Sounds about right as my CV is 16' long.

Love the way that dash and those gauges look !! 
I'm planning on some black plexy/acrylic for my dash - great to have a picture for motivation

Thanks Dan, i really felt like all these gauges were over kill for an outboard, but I'm addicted to information.
and i figure i will always have an older motor and would like to keep tabs in its operation.
this GT was painted that way when i got it, so I'm just making do with whats there, but i would prob have picked the black as well.
I am just glad to here others share the obsession  ;)

There's no-such-thing as too many gauges.

finally got the control mounted... was kind of a PIA
fabricated that plate from some cool looking alum (glove box door) from one of the donors.
it covers the mounting holes from the old control.
and the switch panel from the same stuff.

I love the concealed control box! Best way to go IMO. Brushed aluminum plate looks great too. I am excited to see you finish this thing.

A lot of messy work Joe but you're getting to the more fun stuff. Was your dash changed? It looks great! I thought gt 150 dashes were pretty vertical. Yours appears to slant back more like a CVX.
