    I/O (Sterndrive) Conversion to Outboards

    I fillet-ed most of the day . . . I got the ones done that can be done. There will be some more when I put the remaining pieces on. I'm going to be traveling for the next 10 days or so. I might get a little bit done tomorrow AM, but that's about it for a while. I'll be glassing after...

    I/O (Sterndrive) Conversion to Outboards

    I'm waiting for some Cabosil to arrive . . . Meanwhile I got a supply of frosting bags from the Admiral's stash. In other news, I got the transom pretty much cleaned off. . I'm going to mark the cut-outs in the transom from tracing the openings in the extension pod (going to put the extension...

    I/O (Sterndrive) Conversion to Outboards

    Who wouldda thunk, resin PB as a desert topping :ROFLMAO: Anyway . . . I have been doing the really boring stuff . . . rounding corners, sanding, etc. Fillets come next. I assume that with the PB and frosting bag, I should mix it in small batches, as it will tend to harden-up as I go. My...

    Strange exhaust behavior during winterizing

    Your engine probably can hold upwards of 5 gallons of liquid in the cooling system. If you drain the system and want to fill it with AF, it is best to fill it manually via the thermostat housing and the hoses to the exhaust manifolds.

    I cut the web holes . . . I need to get something for the stiffeners. . There are quite a few corners that I should probably add the rounded fillets . . . Anyone got tips/tricks for making fillets.

    I/O (Sterndrive) Conversion to Outboards

    Back on topic . . . I've been toying with the idea of web holes in the 3 girder-like stringers in the extension pod. This is what I came up with . . . . . There is the one 'center stringer' and two 'engine aligned' stringers (one either side of the center stringer). Since these stringers are...

    Imma sand with 100 grit once I get the paint off. There is also an epoxy barrier coat that I can see under the paint.

    I/O (Sterndrive) Conversion to Outboards

    I got the transom pieces cut . . . they are loosely attached for now, as are the planing surface pieces. It sort of looks like the 3D model ? :unsure: . I have to box in the chine strakes. In the 3D model I had them with no reverse chine. As built, I gave them a bit of lift. (arrows) ...

    I/O (Sterndrive) Conversion to Outboards

    Check point on the weight . . . The Coosa actually used (not what was bought) comes in at about 140 lbs. I'll probably cut some web holes for accessibility . . . weight savings would be minimal (20 lbs +/-). I did see that the rigging conduits come in 2" and 2.5" . . . So I'll plan on the 2.5".

    I/O (Sterndrive) Conversion to Outboards

    Like the Titanic had ? :ROFLMAO: Yes, . . . as a matter of fact, the CY 338 OB version actually has 'covers' over the openings to the bracket. Not sure how water tight they are, but they look to be OK for a rapid flood event.

    I/O (Sterndrive) Conversion to Outboards

    A few more progress pictures and some questions . . . I have the transom pieces to cut-out today and then focus on gussets and stiffeners, most of which I'll pre-form and add after the initial fiberglass layer. Questions Du Jour: Rigging tubes . . . Inside diameter (ID) ? 2" . . . 3" ...

    I'm going to lock this thread for now . . . The OP has not posted additional information, and the dialog has taken on a life of its own, and not in a good way. @stopngo , please reach out to a Moderator if you have additional information and want to re-open the thread.
