    I/O (Sterndrive) Conversion to Outboards

    Covered in a few places in this thread, but to summarize . . . Boat looses about 500 lbs of weight. CoB (center of balance (CoG) moves back about 9". The buoyancy added by the extension pod will raise the stern (at rest) about 2.5". No additional fuel tanks . . . The best place for fuel...

    I/O (Sterndrive) Conversion to Outboards

    Hole-y extension pod . . . I got the access holes cut. There will be 4 additional holes closer to the transom for accessing the engine mount through-bolts. Probably going to order the deck plates before cutting those holes for an assured fit. . . . . I think my bod will fit through the...

    I/O (Sterndrive) Conversion to Outboards

    I have great ambitions of loosing 20 lbs. before boat launch. :LOL: I like the rounded corners idea (y). . . came up with this . . . 5" radius corners. . . . they look like they will retain decent strength at the corners. Probably will be big enough for me. The purple lines are where a 4"...

    I/O (Sterndrive) Conversion to Outboards

    It seems like winter has arrived . . . 37˚F today :rolleyes: I have started to map out the access holes, which will be at the transom face and the top plate which mates to the underside of the swim deck. For the transom . . . I was initially thinking that 18" diameter would be OK, but...

    I/O (Sterndrive) Conversion to Outboards

    No, I already have 2 boarding ladders on either side of the swim deck that will remain intact.

    I/O (Sterndrive) Conversion to Outboards

    Some ask why, I often ask why not . . . :LOL: Gonna be sort of a splash well, but it is really to access the top mounting bolts of the engines and clearance for rigging (steering actuators)

    The moisture meter that the surveyors use will most likely be the Tramex Skipper. It is designed to check the moisture through fiberglass. A contact-based moisture meter (like the ones for about $50) require access to the wood substrate and are not effective in most marine applications...

    I/O (Sterndrive) Conversion to Outboards

    The waters subsided and I was able to get the 2 'planing surface' pieces done. . . They will stay loose for the time being, as I'll need access to the insides. Tomorrow should be the transom pieces.

    I/O (Sterndrive) Conversion to Outboards

    Yes, absolutely . . . already in the plan. Meanwhile . . . the waters are rising :LOL: . . It looks like I won't be cutting any more big pieces today. :unsure:

    I/O (Sterndrive) Conversion to Outboards

    I'm working inside the garage today, as there is off & on rain. The space is a bit cramped, but I'll make do. As for the remaining large pieces, I have 5 more to go . . . . #1-3 will be 1/2" thick sheet and the #4 & 5 will be the 1" sheet. Then I got to double-up the #5 panel to get towards...

    I/O (Sterndrive) Conversion to Outboards

    The hull gets partially extended by 3.5 feet, it is not a full width extension. This is often called an extension pod.

    I/O (Sterndrive) Conversion to Outboards

    I was thinking about you the other day, good to 'see' you . . Yes, Page 7 , post #130 . . . I calculated the center of balance will move aft by 9 inches . . . the stern will be up by about 2 inches. Total weight goes down by about 500 lbs.

    I/O (Sterndrive) Conversion to Outboards

    It was supposed to rain this AM, but the rain held off 'til PM . . . I got some more pieces cut. . The extra 'stringers' are in line with the engine locations and notched for the splash well. I'm running short on the Coosa, but will see how much more is needed. I got a 1" thick sheet and a...

    I/O (Sterndrive) Conversion to Outboards

    Thinking about next steps . . . At some point (soon), I'll need to cut some access holes in the mating surfaces of the Ext-Pod. These holes (obviously) would be needed for installation and maintenance . . . and probably fabrication. I'll be making a matching set of holes in the transom and...

    I/O (Sterndrive) Conversion to Outboards

    Yes, please and thank you . . . (y) I have some stainless steel "L" angle stock that has been sitting on a shelf waiting for a purpose. Wondering if that would fit the need? I assume the 'cap' is to distribute the load. :unsure: On a different topic . . . I know the outboard motor industry...
