    I/O (Sterndrive) Conversion to Outboards

    IDK . . . It will be whatever the re-power shop typically uses or thinks is best. I believe it will be 3-blade.

    I/O (Sterndrive) Conversion to Outboards

    Quick Update . . . I stopped by the re-power shop today to check on the fit of the trim tabs. Looks like I can cut the existing tabs down by 2" (making them 16" x 12") and they should be able to go back into the existing holes. The engines are mounted and the steering parts should arrive...

    persistant overheating issue.

    I would get an IR thermometer and get temperature readings all throughout the cooling system, particularly when it is running hot.

    persistant overheating issue.

    Have you taken the end caps off the heat exchanger to check for calcium build-up blocking some of the tubes? BTDT. :oops:

    Early 2000's Rinker

    To that point, Rinker was not one of those 'better build quality' brands . . . They tended to be more on the Bayliner end of the quality spectrum.

    I was getting around 1.2 mpg with the Mercruisers, so there is not room to go but up :ROFLMAO:

    I/O (Sterndrive) Conversion to Outboards

    I know it generally works with cars, so it may follow suit with the boat engines. I'd be looking for a change (improvement) in fuel consumption and not a specific value. I've done this with cars and have seen a noticeable jump in fuel mpg around a certain mileage . . . it has ranged from 15K...

    I/O (Sterndrive) Conversion to Outboards

    Yes, broken-in, but not broken :LOL:. . . apparently the term came from the 'breaking' of horses (so they could be ridden). According to AI . . . "The term "broken-in" (or "break-in") originated from equestrian terminology. Historically, it described the process of taming and conditioning a...

    I/O (Sterndrive) Conversion to Outboards

    I’ll just do what the manual says, but I think the link that AD posted is about right. i think also I can watch the fuel consumption, as that can be an indicator of being ‘broken in’.

    I/O (Sterndrive) Conversion to Outboards

    The CG (Center of Gravity) . . . as best that I could calculate . . . is going to move about 12" aft and 5" upward. The Savitsky analysis done by the Naval Architect showed the boat would be at only a slight upward angle at rest (0.3˚). Some folks do a live test of the boat before the...

    I/O (Sterndrive) Conversion to Outboards

    Looks so . . . I did not measure it. There will be an additional 2,000 lbs of buoyancy from the extension bracket. I expect the stern to be up a 'wee bit'. :D

    Speaking of WOT . . . In discussing propeller pitch with the re-power shop we came up with a 19” pitch as the starting point (19 x 16). Estimated top speed would be in the 51-53 mph range if the engines can make their WOT speed of 6,000 RPM

    I/O (Sterndrive) Conversion to Outboards

    Trim is the angle of the keel vs. water level. So, a zero angle would be even with the water level. Generally, you want a slight upward angle at rest and not too much upward while underway. I’m hoping for a slight up angle at rest (0.5-1.0 degrees). And less than 3 degrees underway. The...
