    Fixx,
    For me, I prefer LP over the Kero..........I've been in buildings where both were used - propane fan forced ceiling heaters (CO detector w/ cracked door) may be the lesser of 2 evil's, but a Kero heater gives me a headache imediately even with the sented fuel additives.
    I'l be using a 100 pound LP tank (approx. 23.5 gals) not the 20 pound gas grille tank.
    Remember it's 200,000 btu's and although it's a convection heater, I still have 2 ceiling fans in the "Mag dome" to push the heat around. After I blast (that's a poor word) up the heat I'll resort to smaller electric heaters for the glassing.

    A flat sheet of 1/4" neopreme would not give me the air circulation around the bottom of the tank as would the varied placement of squares. Jim, the picture above shows the welded brackets on the tanks, I'll take more pics as I go along.

    Sippy -Pete,
    They look like pretty nice tanks, and doesn't sound like a bad deal at that price. do they have internal baffles?
    Understand about the venting under the tanks, as you will randomly place the squares under the key areas of the tanks.
    yes see the backets mounted on the tanks

    thank you
    Jim

    Magnum engine hatch

    I want to replicate an engine hatch for the one that's missing on my '76 Mag sport. looking for some good pictures to get a general idea of what the plug should look like..........might even build a "one off" from a male mold. The picture below is Aron's '74 Sport. This is what I'd like to build for my boat, just looking for some different angle shots.

    Hey Aaron,

    Just wondering if you could measure either from the top of your transom assy to your rubrail or from the bottom of the assy to the hull bottom. Trying to get as many figures as possible before I re-cut my transom.

    Thanks - Marshall

    Yeah..no problem. I keep meaning to do this....my boat was re-rigged with Bravos and it works very well. 320EFIs with 21p Mirage plus'...runs 67 mph GPS with a half tank and two fat guys on board...crappy bottom paint too. When I redo the bottom, I should touch 70mph...

    Last yr with 420hp a side I ran 71mph best so I'm hoping for big improvement with the raised bravo's and more hp. Should be cutting the transom in 3 weeks.

    Finally,.....got two good days of weather last week to remove (old undercured patches) and re-glass in the exhaust holes in the transom. Also, I backed the TRS cutouts w/melamine & started with 2 layers of Mat (from the inside) ........................as expected, everything kicked really nice (weather was in the 70's) compared to the "gummy gumbo" I cooked up a couple months ago.

    After gluing (epoxy) together the two 3/4" ply inserts for the core of the new transom, I fitted it one last time before it's permanently seated in hull & deck putty.
    I used 2X3 bracing within the boat to fix it in place. The bulkhead forward of the engine bay was plenty strong to support the bracing.......I never intended to use screws, just couldn't see patching more holes. Next I have to fillet al the corners before the first course of 1708 is applied, then replace the stringers to the new transom.

    Pete!
    This looks great!
    Now you're an expert.
    That's as fine a job as you could hope to see.
    How about some shots of the outside?

    Scippy,

    Looks good! Glad to see you making some headway. Is your deck off? If not what is your plan for installing the stringers, dont the main ouside ones attach to the big pads that support the cockpit floor? My secondary stringers run about 18" forward of the eng room bulkhead.
