    I/O (Sterndrive) Conversion to Outboards

    The extension bracket is fitting better. I think a 1/2" spacer will do the trick. . Here is the starboard side . . The port side seems to be the issue, as it flairs out about 1/4" at the bottom. The spacer and maybe a little bit more grinding here and there should do the trick. Using deck...

    I/O (Sterndrive) Conversion to Outboards

    Checking the measurements on the transom face vs. the extension bracket. . . The width of the top is fine (actually 1/2" to spare) The lower portion looks to have flared out a wee bit . . . probably during the framing of the outside stringers. I did some grinding (not a lot) and will see how...

    I/O (Sterndrive) Conversion to Outboards

    I can also get a 5 gallon pail of 'hull & deck putty' for $315 . . . I'll have to verify if it is VE or Poly. (prefer VE)

    I/O (Sterndrive) Conversion to Outboards

    I am leaning this way . . . I think the stuff is often called structural putty or deck putty. Basically, PB with a fiber content IIRC. I think I can get VE structural putty . . . . . Or perhaps make my own. I can get VE resin for $49/gallon and I have lots of fiberglass material to chop up.

    Pushing Run-Flat tires to the limit

    They only use turn signals when they are not turning.

    I/O (Sterndrive) Conversion to Outboards

    Looking ahead . . . the test fit is also serving as a rehersal of the actual installation process. My plan is to . . . Position the extension bracket near the boat/transom Apply prodigious amounts of permanent adhesive to the contact areas Pull & lift the extension bracket tight to the boat...

    Pushing Run-Flat tires to the limit

    My car is a BMW . . . has no spare tire, no car jack, etc. My guess is that with this brand of car, you are not supposed to get your hands dirty :ROFLMAO: . Anyway, we are keeping our cars and spend money on the important things in life . . . like boats :LOL:

    I/O (Sterndrive) Conversion to Outboards

    Something isn't right . . . My geometry calc's are indicating that the extension bracket would have to be off by about 3/4" on the width to be stopping 5/8" short of the boat's transom. (possible, not plausible . . . :unsure: ) I have a hunch that it may be a matter of height, not width. So...

    I/O (Sterndrive) Conversion to Outboards

    When I made the transom mating surfaces, I used corrugated cardboard as a 'padding' to mimic the thickness of fiberglass. . . . Of course, if the fiberglass is thicker than the cardboard I used, it would explain the fit problem. The fiberglass was 2 layers, so about 0.09" each side . . ...

    I/O (Sterndrive) Conversion to Outboards

    The extension bracket needs a tweak . . . After much effort, the extension bracket would not come all the way flush with the boat's transom. I suspect that the bevel sides are a 'wee bit' thicker/wider than my original take-off from the transom, even though I made some accommodation for...

    I/O (Sterndrive) Conversion to Outboards

    I did a 'test fit' today . . . . . . . . . . I need to do some adjusting to get it snug to the transom . . . It's about 1/2" away . . . (13mm :p )

    I/O (Sterndrive) Conversion to Outboards

    Yes, on the sealing up of the balsa . . . I usually use some resin for that purpose.

    Pushing Run-Flat tires to the limit

    4 new tires went on yesterday . . . Bridgestone DriveGuard Plus RFT The car rides nicely. The Admiral's car went in for a couple of recalls (roof rack and rear strut). My car has a recall outstanding . . . something that can cause a fire. I suppose if the car caught on fire, I'd have to get...

    I/O (Sterndrive) Conversion to Outboards

    I still use imperial units of measure . . . According to Google . . . "While the U.S. has a policy to adopt the metric system (Metric Conversion Act of 1975) and federal agencies are required to use it, imperial units (customary units) persist in specific industries like civil construction and...

    I/O (Sterndrive) Conversion to Outboards

    Quick Update . . . I had a feeling that the underside of the swim deck was fairly substantial in its construction . . . . It certainly is . . . . . . 1.05" total thickness 0.33" Fiberglass 0.50" Balsa 0.22" Fiberglass It has a wee bit more fiberglass than the transom :oops:

    I/O (Sterndrive) Conversion to Outboards

    Transom holes are done. . . I also drilled the drainage holes that will let bilge water flow to the extension bracket where there will be a garboard plug. . The 4 holes on the underside of the swim deck are next . . . but . . . there is a vent tube in the way. That will be tomorrow's project...

    95 Sea Ray 230 Sundancer stringer repair

    Do the 'burn an inch' technique to get a more exact measurement, but generally you want the core to have been 1.5" . . . looks like you are at 1.75"
