    I/O (Sterndrive) Conversion to Outboards

    Yes, DIY bracket, and using re-power shop for the engines and controls (exact shop still to be determined). Plenty of re-power shops in the northeast. There are about a dozen within 25 miles of me. Where there are boats, there are re-power shops. Engine warranties would not be impacted by...

    I/O (Sterndrive) Conversion to Outboards

    OK - I've done some quick reading on the Optimus joystick stuff. I think I got my head wrapped around it now . . .It looks like either Mercury or Suzuki engines brands will require Optimus in order to get joystick, Yamaha has Helm Master EX. So, I'm going to confer with the re-power shop as...

    I/O (Sterndrive) Conversion to Outboards

    In the area of engines, I finally got some clarity on Joystick piloting of Mercruiser vs Mercury. Here is a summary from Google AI. . . "The Mercury outboard equivalent of the MerCruiser Axius system is Joystick Piloting for Outboards (JPO). Both technologies are part of Mercury's broader...

    I/O (Sterndrive) Conversion to Outboards

    As I look at engines, particularly in the Yamaha and Suzuki product lines, I am finding the model numbers as clear as mud. . . The first part of the model numbers are pretty straight forward, the last few digits seems to be all over the place Example . . . the model F300X is 25" shaft, . ...

    I/O (Sterndrive) Conversion to Outboards

    So, if the accrual was at little/no profit . . . Figuring $3k for 3 year extension and 17% needing repair during the extension period . . . 1/(0.17) x $3,000 = $17,647/repair (which seems high) I figure that there must be a fair amount of profit in the pricing :unsure:

    I/O (Sterndrive) Conversion to Outboards

    The pricing for extending the base warranty looks to be $1,000 - $1,200 per year, which seems high, as that figure would be an average. Not sure how much of it is clear profit, but at ‘flat’ rate, every 10th owner would have a $10K repair bill each year. 🤪

    I/O (Sterndrive) Conversion to Outboards

    As for extended warranties- Yamaha seems to be about 15% lower than Merc and Zuke. It looks like the standard warranty is 3 years for M and Y, 5 years for S. I’m not a fan of warranties anyway, probably would stick with the base warranty.

    I/O (Sterndrive) Conversion to Outboards

    The CoG Moving back might be OK considering that there will be quite a bit of buoyancy and planing surface at the stern.

    Cars you should have kept.

    'Torino' wasn't a brand until 1968 . . . Was it a 67 Fairlane, or a later model year Torino? I think the Gran Torino was 1972-76. My parents had a 1961 Ford Sunliner (that would be a nice collector car now) Parents also had a 1966 Fairlane convertable . . . and a 1968 Plymouth Fury 2-door...

    Robalo2440 1995 Nav light needs repaired

    'Aqua Signal' and 'Perko' make many navigation lights. So you might want to Google search a bit to find a new top part (light fixture). The one you have looks like a Perko 'masthead/all-around' style.

    Crack on drive unit - how concerned should I be?

    It's certainly not good. :unsure: I'd see about getting it fixed (if possible). . . it will probably get worse.

    I/O (Sterndrive) Conversion to Outboards

    After some review of the boat hull (from pictures), I realized that I had the hull strakes slightly off. The upper strake does not line up exactly with the chine of the hull extension. Here are a couple of pictures with the strakes shown and adjusted accordingly. . . . I should be getting...

    Solar charging batteries

    I did the solar charging thing over the past few years. You will probably want a solar charge controller, one that has setting for LiFePO4. I also found that when the LiFePO4 batteries are full, they shut off charging, so the controller may have current with no place to go. So you may get a...

    I/O (Sterndrive) Conversion to Outboards

    The more I read about the design of hull steps, the less inclined I am to having the 2" step. Here is a rendering of the E.B. without a step. There is a strake right at the chine of the extension (not previously detailed) that I could run to the end of the extension. .

    Bought my first boat to cut, gut and rebuild from bow to stern, including engine. Killed my back and suffered the wrath of the fiberglass demons

    Think twice (or 3 times) about renting out a trailer. Bad things happen to good people. :unsure: Hopefully you will get back to the boat work soon?

    Links at top - shopping on iBoats?

    I was on BoatingABC for quite some time as well. IMO, the technical level here on iBoats is much higher, and probably one of the highest among the popular boating sites. BABC went away one day without notice. There was just a handful of people who frequented there an I would imagine the admin...

    I/O (Sterndrive) Conversion to Outboards

    As for stats & numbers . . . If I build the extendo-bracket (EB) myself, it is looking like $5-6K including the gantry for materials and supplies. I am thinking to have one made is probably $12-15K. I have estimated the weight of the bracket in foam/fiberglass at 475-500 lbs. If aluminum, I...

    I/O (Sterndrive) Conversion to Outboards

    One thing that I am still thinking over (or maybe over thinking :LOL: ) is the 2" step (up) of the extended planing surface. I see a lot of hull extensions that are done with the added planing surface flush with the existing hull, rather than a step. I'm thinking the step will allow some air...

    I/O (Sterndrive) Conversion to Outboards

    Yes, I was thinking of exactly that. Since there will be a 2" step up, I could have a drain hole back to the main bilge.
