I’d like to see that. I also like the idea of a complete cradle under the engine with the cradle sitting on top of the stringers/floor but not really necessary as it isn a race boat.I'll try and get you a picture of the stringers and brackets soon. It's not a bad way to mount the engine..

Hi Jeff,Hey bro,
loving the build. I have an 89 Wellcraft with Merc 4.3l Alpha one that i am fixing the same issues, but in a different way. (not better just different)
You obvouisly know what you are doing. Some of your tips have been really good (eliminating water creep between wood pieces)
After evaluating my boat piece by piece as i disassembled, my motto has been, "Seal the top and open the bottom". Every stringer that had a place for the water to escape is still solid, every piece of wood that was sealed at the bottom filled up with water and rotted.
You know how it is with boats, FRP all you want, water will find the wood and leak into the deck, stringers and transom.
My thought as i put my boat back together is give every stringer some type of drainage down to the tunnel so water doesn't have a chance to pool.
Are you creating any type of drainage system for the "sealed" parts of your boat?
I haven't seen any good battery mounting options, you got any good ideas?
Thanks!

What size of 1708 roll do you recommend? I purchased one roll that is 4 inches wide, don't know the length. Will i need wider 1708 for the transom or will that make it harder for a novice FRP guy?Happy with the results of this weekend - stringers are glassed in.

Had to change plans a bit as I was planning to do the second layer as a single piece over the top and down both sides but trying handle 14 1/2’ long by 3 1/2’ wide of wet out 1708 on my own would have been too difficult, especially under the bow section. Instead I cut it down the centre and will do a wrap over the top of each stringer (to fully seal it) once the glass has been tidied and sanded to key it.
Question - Should I use 1708 or a csm/woven roving/csm combo? I’m leaning towards the combo as eaier to handle as individual lengths. Let me know your thoughts.
Tied each stringer back onto the transom so loads are transferred into the structure

Learning points:
1. The 1708 really doesn’t like going into tight gaps and I struggled to get it into the chine so put some pb in the starboard side to give a shallower radius

2. 1708 should be fully wet out before laying it. Best method is with a squeedgy to spread the resin.
3. Don’t bother doing neat fillets. Use the icing bag method to lay a nice thick bead into the corner and lay the wet out cloth into place. Use your hands to position it and smooth it to get the majority of the air out on one side of the fillet so it held firmly (in my case to the vertical side of the stringer). 1708 doesn’t stretch so you then use your roller to push it into the fillet and then roll the surplus pb away from the corner. Much quicker, no bubbles and no issues trying to make/sand perfect fillets. This also works to fill gaps where they were heavier on one side of a bulkhead than the other with the chopper gun and there is a step in the fibre glass thickness without having to grind loads of material out.
4. Make sure the pb has some chopped strand in it so it’s not too brittle.
Hope that makes sense - ask if it isn’t clear.
Now need to order more supplies as I’ve used about 24kg of resin, need cabosil etc. I’ll cut the bulkheads and cleats while I’m waiting. Once they’re in, on to cutting out the floor!

Just buy a full width roll (38" or 50"). Then you can cut strips to the desired width. I used a 50" roll. For tabbing, I would cut my strips to the desired width off the roll, then cut them in half so they were 25" long. This size was easy to handle by myself, and if you're doing 2 layers, you can alternate the gaps between pieces on each layer (like stacking bricks), and still have plenty of strength.What size of 1708 roll do you recommend?

Exactly this. The 1708 has advantages and disadvantages over separate csm and clothJust buy a full width roll (38" or 50"). Then you can cut strips to the desired width. I used a 50" roll.

Thanks, i probably need to figure out how much i need. Those rolls sound like a ton of material, i doubt i would use half of it. Biasbilt twisted my arm and made me commit to posting my current build. Clarity .... AND confusion will come once you see it.....LOL Is there a Jerry Springer build forum somewhere? ..... cause there is gonna be drama! LOLJust buy a full width roll (38" or 50").

To clarify, I'll bond in a fibreglass tube to seal the wood. Fibreglass tube as the poly resin doesn't bond well to plastic plumbing pipe.good thoughts,
For some reason I can't conceptualize "resin a tube"? Does that just mean drill a hole and pour resin inside?
Good thought on the bolts, I had not considered either of those things. Replacing a stripped bolt or sliding the engine. I guess lag bolts work (much better in an epoxy bed) , i am probably just stuck in my ways as a mechanic, I would never use a wood thread on a car. I guess years and years of using lag bolts with success should be good enough for me to get over my bias.
So do you buy fiberglass tubes or make them, I have never seen them for sale?To clarify, I'll bond in a fibreglass tube to seal the wood. Fibreglass tube as the poly resin doesn't bond well to plastic plumbing pipe.
