    I/O (Sterndrive) Conversion to Outboards

    OK . . . this took a while. . . . at least 2 hours, maybe 3. The first piece of exterior fiberglass (96" x 50"). It covers the planing surface and a little bit down the sides. I mixed up 3 1-quart containers of resin and activated them as I went. I was figuring it might need a little more...

    I/O (Sterndrive) Conversion to Outboards

    My apologies to @redneck joe for the 'upside downess' over the next few days while I glass the external surfaces. Yesterday was corner and edge rounding day, along with the thickened fiber paste for smoothing out the transom and forming a large fillet at the back of the planing surface. . ...

    95 Sea Ray 230 Sundancer stringer repair

    IIRC, @alldodge did a partial transom restore on his Formula 27 about 8-10 years ago. If the wet/rot is localized at the bottom of the transom, a partial replacement may be do-able. . . a judgement call for sure.

    I/O (Sterndrive) Conversion to Outboards

    It was Plan B . . . The snow had softened up with the warmer weather to a point where I was able to clear out under the gantry . . . . . I made special dolly to fit the extension bracket . . . . and stuck it under there, so I could roll the E-B out of the garage to under the gantry. . . ...

    95 Sea Ray 230 Sundancer stringer repair

    I had rot in both of my Formula boats (a 242 and a 330). It is a 1990's (and earlier) thing across most of the boat brands. First thing to do would be to determine the extent of moisture and rot. I know that you have exposed some of the stringer, but the issues tend to go further than you...

    I/O (Sterndrive) Conversion to Outboards

    Lifting Update . . . I bought a shop hoist to lift the extension bracket. Some assembly was required. Then, I put a couple of U bolts in through the top plate to hook onto. . . I figured if I can put it on dollies instead of blocks, I can move the thing around as needed. . . . EXCEPT . . ...

    I/O (Sterndrive) Conversion to Outboards

    The top plate laminate (Post #888) is 2415. I may be adding some 1708 in the area that will be 'exposed' behind the swim deck. the rest of the surface will have a plethora of through-bolts.

    I/O (Sterndrive) Conversion to Outboards

    This is the biggest single piece of fiberglass (50 x 90") and took a long time . . . probably 2 hours start-2-finish. 100 oz. of resin. . . I initially tried to soak the resin into the cloth top-down . . . that didn't work. So, a quick change on the fly to soak the Coosa board with resin and...

    I/O (Sterndrive) Conversion to Outboards

    I do have some micrometers that I could break out, but the handy electronic one is good enough . . . :LOL: I'm just checking my laminate dimensions . . . The Coosa measures right at 1.00" . I have the following laminates on the transom now: 3 x 1708 (0.045" typical thickness) 0.135" =...

    I/O (Sterndrive) Conversion to Outboards

    Yes as I was taking measurements, I was wondering how flat the outside of the transom should be so as not to distort/crack the engine bracket. The straight edge is probably the way to go.

    I/O (Sterndrive) Conversion to Outboards

    Happy Friday . . . Of course, every day is the same for me, being retired. :LOL: I'm getting ready to glass the top. It has been a good cutting and roll-out platform, but now it's time for its glass. . . . . I need to 'flip' this thing over to do some corner rounding and probably will...

    I/O (Sterndrive) Conversion to Outboards

    I put a layer of 2415 cloth on the transom today. The thickness is at 1.40" +/- . . I'll be looking to get into the 1.90" range. Probably something like . . . 1708/1808/2415/1708/1808 to get to around 1.95".

    I/O (Sterndrive) Conversion to Outboards

    Quick Update . . . I got the 'top cap' rounded and put a layer of glass (1708) up and over the transom. There will be quite a few more layers to go. . . I still needed to put another layer of tabbing on the transom/stringer joint. So, I decided to try out the 2415 cloth. . . It actually...

    I/O (Sterndrive) Conversion to Outboards

    The 1808 is pretty similar to the 1708, but perhaps the strands are not as tightly stitched. The problem with the 1708 is that it is strongest in the -45˚/+45˚ directions. Often you need a mix of cloths so that you get strength in all directions (-45,0,+45,90). Also, if you need strength in a...

    I/O (Sterndrive) Conversion to Outboards

    More transom work . . . I am planning on a top cap of 1/2" rounded Coosa for the transom. But, before I added the cap I wanted to put several 'bands' of fiberglass (1808) in the areas between where the 2 splashwells will go. These will provide about 10,000 lbs of strength directly in line...

    I/O (Sterndrive) Conversion to Outboards

    I/O (Sterndrive) Conversion to Outboards

    I was never concerned, knowing you got your hands full. Tomorrow is fillets and tabbing of the transom. Tuesday, I am going to pick up fiberglass supplies in MA and CT. Hopefully this will be it for the major purchasing. Since I'm picking up the materials, I am getting the 5 gallon pails for...

    Getting impatient

    Every time I look at my boat (in the yard) the snow gets deeper . . . :rolleyes: I'll be happy if I can start doing stuff on the boat by April.
