Incredible! awesome job.

imagine how much it would cost for production manufacturers to pay this much attention to detail....

I molded a pair of fiberglass tubes like that for my Mako21 a few months before Katrina, but I haven't touched the boat since then. I also molded a pair for my Mako26 about 8 months ago, and I plan on installing them in about 2 months.

I'm glad to see someone put the same kind of plan into action. However, I never thought of having any of the drain lines exit through those scuppers. Ingenious.

Basically, I wrap the mold in thin plastic. That way I don't have to spend time waxing the thing and the part comes off alot easier. It doesn't have to be perfect anyhow. I use 1.5oz mat for the flange and 6 oz cloth to wrap the actual tube. There are about 5 wraps of the 6 oz cloth. I used the 1.5oz mat to tie the flange onto the tube in the glassing process.

I have some cleaning up to do, but these are all set to go into the boat when that part of the project comes up.

Those drain tubes turned out GREAT!! What kind of plastic did you use and how did you adhere it to the mold?

I used 2 mil plastic sheeting (visqueen). The mold is simple. Two pieces of 3/4" MDF screwed together with the edges rounded over with the router.

The angle between the transom and the deck was taken and I used my miter saw to cut that angle into the end of the tube section that mates up the the base (which makes the flange).

I covered the base of the mold with a piece of plastic and then wrapped the tube section with the plastic just like you would wrap a birthday present (I just made sure I wrapped it tightly). Then I screwed the wrapped tube section to the covered base.

I start by glassing the junction between the base and tube with little hunks of mat. I just tear hunks off of a sheet of 1.5 oz mat and place them on the spot and dab them to place with a brush of resin. I built it up pretty thick. Then you can see in the first pix that I cut a full piece of mat to fit around the tube and that makes the flange. Once I get the flange glassed and the mat working its way up the tube (about 1" up or so), I start wrapping it in layers of 6 oz cloth. 5 or 6 wraps and its about 1/8" thick.

Did you mate the flange to the outside of the transom???

RingLeader · #46 10-26-2006, 10:11 AM

I haven't installed them yet, but the flange will mate to the outside of the transom. The cut out for the tube to traverse the transom will be bedded with thickened epoxy resin as well as the flange mating to the transom. Then the flange will be glassed over and faired flush. A fillet will be made on the inside skin of the transom around the tube and a layer or 2 of glass will be tabbed there.

The floor was made outside of the boat using a pattern, seen here leaning up to the left. The underside has been glassed.

The top side of the foam core won't be glassed until in place. Cutouts were made for fuel tank and battery box access, as well as for the control and wire chases.

Floor bonded in place.

I plan to access the battery boxes, macerator pump, and tranducer through a seat in front of the console (the hole through the floor of the lower battery box in the picture is for the transducer tank). Access to the fuel tank and the control/wire chases will be in the console itself.

Hello Bonefish - I am restoring a 74 23 Tsunami up the road from you in Charleston. What kind of foam are you using for those bulkheads and the new cap on th transom (green foam)??? Also, are you able to bond resin/glass directly to that foam?? Thanks - Robert

Looks good. I hope that your are able to through bolt the console with nuts and fender washers, if not then the screws will pull out of the floor due to the foam core not having any holding power. What a lot of the boat manufactures are doing is glassing in plywood or an aluminum plate in these areas.
