    Support for new floor

    At one point the foam was closed cell, but over time, it can become saturated leading folks to think it is open cell. It looks like there is only room for 1 stringer, and I agree with @racerone that the foam was serving as some structural rigidity. If you wanted to 'beef-up' the structure...

    I/O (Sterndrive) Conversion to Outboards

    I think the gelcoat I have is poly-based. Not sure, but probably.

    I/O (Sterndrive) Conversion to Outboards

    I picked up a couple of gallons of Vinyl Ester fairing compound on the way to CT . . . Feels pretty light. I might have gotten a 5 gallon pail, but I hoping what I got will do. Ondarvr told me that if I go with VE fairing, then I can gelcoat. If I went with epoxy fairing, then it would...

    I/O (Sterndrive) Conversion to Outboards

    Speaking of fiberglass cloth and such . . . I did a cross-check of my fiberglass usage vs how much Coosa board used to build the extension bracket (probably should have done this day 1 :rolleyes: ) 6pcs x 48"x96" x 2 sides x 80% utilization = 44,236 sq. in. of Coosa to cover with fiberglass...

    Yes, I'll probably combine a few methods 'a La' drywall smoothing. Often when doing stuff that is non-textbook, I see what is working and adjust accordingly. In other news . . . the 'ransom note' on my 1708 shipment (or lack thereof) has been posted on the delivery status "Your package is...

    The bolts stay where they are. The engine gets moved up to another set of holes. That’s how engine mounts work.

    I/O (Sterndrive) Conversion to Outboards

    I got the 5 gallon pail of VE resin, but the delivery person must be holding my 1708 cloth hostage or something. Awaiting a ransom letter. . . Meanwhile . . . I have taken a look at the transom. Flatness, height, bolt positions, etc. . . Flatness: I am thinking that I could use the cut-out...

    I/O (Sterndrive) Conversion to Outboards

    OK, my fiberglass estimates have been way low and I am heading out to grab another pail of resin and another roll of 1708 should arrive today. I took a look at what I've used and it is adding up (resin vs. cloth), but it seems that making things thick really uses up the materials, since each...

    I/O (Sterndrive) Conversion to Outboards

    I believe the I/O spec is thickness and how 'parallel' the inside & outside surface need to be. I'm trying to find what outboard motors need, but I would imagine it mainly applies to the outside surface.

    I/O (Sterndrive) Conversion to Outboards

    In search of flatness. . . . OK, the transom as it is now is not very flat. . . . Most likely from lamination overlaps, etc. I am not sure fairing compound (I have a source for VE fairing compound), is the right thing for the mounting area of the outboard. . . but maybe it is. :unsure: 'Plan...

    I/O (Sterndrive) Conversion to Outboards

    1 Splashwell formed I had a remnant of 1708, so I was able to form a splash well after the base pieces had set up. This is the starboard side. . . . I'll need to get some more 1708 to form the other one, but for now this worked ! My plan is to beef it up with 4 layers of biaxial. . . Imma...

    I/O (Sterndrive) Conversion to Outboards

    Progress update . . . I got another layer of 1808 on the transom from the inside 'up&over' to the outside and around underneath to the 'bottom plate' The transom is getting fat, as it should . . . . . Another 0.3" to go . . . Now I'm prepping for the splash wells. This will be some...
