New Project: 170 Aquasport

[MarcG]

Productive weekend, well Saturday at least.  Sunday was Mother's day so no working in the garage!  Transom is in.  Thanks Rick for the advice.  The added layer of 1708 against the outer skin helped add strength and kept the epoxy from oozing out of all the holes.  Did a dry run to make sure my clamping set up would work, then thickened up a bunch of epoxy with fumed silica and troweled it in.  Also added a few boards on the inside to make sure every section had pressure.  To fill in the gap I mixed up another batch with fumed silica and chopped stands of glass, then squeezed it into the gap by filling a ziplock and cutting off a corner. 









I'll let everything sit until next weekend, glass back in the rest of the stringers and a new drain tube, then tab everything back in.

Looks good.

Slow but steady progress over the last few weekends. It's getting a little hot to be working outside in central Florida!

Glassed the ends of the stringers back in, made a fillet around the perimeter and tabbed in the transom. Next will be fitting the chase tubes for the controls.

Each day you work on her it is another checked off task, even if it a "sit and stare" (thinking) day.

[MarcG]

Funny you should write that because I do have a page and a half of tasks written out, checking off as I go.  Finished three more this weekend:  filled the ends of the stringers with 4# foam; roughed in the chase tubes and cut up the leftover CoreLite from the transom for shims to fill the gap between the tops of the stringers and the floor.

Slow progress over the summer, which lasts until about October down here in Florida.  Now that I'm getting my weekends back I'm getting back to work.  I formed the sole out of 1/2 inch CoreLite pvc board and trimmed it to shape with the template.  The bottom and top were glassed over with 1708 and poly resin.  I added a shallow trough at the stern to hopefully help the deck drain and collect any water quickly as it heads to the scuppers.  I used some of the scrap CoreLite to shim up the stringers to raise the floor to the new height.







The new inner skin for the transom is two layers each of mat and roven, followed by two layers of 1708, all in epoxy.  Trying to make this as strong as possible since the outboards I'm looking at weigh close to 400 lbs.

Lookin' good!

Looks good!  Are your scuppers going to be in the center?

[MarcG]

Planning on two towards the middle, maybe 12 inches apart.  That will leave me room in the corners to add two boxes in the back, one for storage and to pass the outboard cables through, and one for a small live well.

The work continues!  Added the fuel coffin back to the new sole.  I trimmed back the bottom skin and core, leaving the top skin in place and bonded the fuel coffin back in. 



Filled the gaps, added a fillet and glassed it to the bottom for strength. 



Faired out the new deck and added the hatch for access to the bilge.  Just about ready to be reinstalled!

Looks good - bet the sole is starting to get heavy now.

Hi Everyone, took a few years off while we moved and did a major home remodel, but the big upside is I now have a workshop to finish my project in.  Just installed the sole, and getting ready to add some boxes in the back, one for storage and one for the livewell.  Before I go any further though, I want to make sure I made the outboard opening in the transom large enough for the outboard.  My plan is to go with a Yamaha 115.  The base of the opening is 18", tapering up to about 24" at the top.  Will this be enough for the motor to swing all of the way side to side, and fully tilt up?  Does anyone have a similar size outboard and a sense of how much of an opening is needed?

Depends on which Yamaha 115 you use... the 115 v4 2 stroke is SUPER wide! I think it will definitely fit with motor straight, but if you were to turn the wheel with motor tilted all the way up, your cowling may hit the transom corners.

I can measure my transom soon but the boat is sadly covered with a tarp and snow at the moment!

I raised my transom wings about 3" from factory, so it's not a direct comparison, but maybe it will help.
