    Someone added this purple wire .

    Wired like it is, that wire will only have power when the Key is turned to 'Start/Crank', and no power at 'Run'.

    Someone added this purple wire .

    That purple wire is not connected at the other end? How long is it? Are you saying it runs all the way to the Helm?

    too much outboard for the boat?

    Looking at the pic, I can see many cracks in the paint/resin, indicating flexing. I agree with Scott's conclusion as well

    too much outboard for the boat?

    How did you come to the conclusion that there is only a small bit of Rot in the Transom?

    Speed Plateaus at 5200rpm

    70hp evinrude pitch size advice

    In the 80s, I had installed what was called True Trim Steering on my outboard. It used a Trim Tab, that was connected to the Steering Linkage, and by rotating the Trim Tab, the Outboard would be steered. It offered a No Torque Experience at all Speeds and Trim Angles. It was a copy of the system...

    70hp evinrude pitch size advice

    That's odd. Boats usually want to pull to Starboard when engine is trimmed in/down, then even out as engine is trimmed out/up, then pulling to Port when trimmed further out/up. That of course us assuming the Prop is not a Counter Rotating

    70hp evinrude pitch size advice

    I did the same test, in the early 70s , when I was a Teenager, and found very similar, results. Acceleration did change though.

    70hp evinrude pitch size advice

    I would verify that the Tach is set correctly, and that it is Accurate. 6000 rpm, with a 19 in, on a 16ft, the numbers appear a bit off

    Is this a long shaft on a short transom and other questions

    I have never seen one of that design run all that well. Mainly because of the Design of the Induction System on Mercs Inline Engines, which is normally decent, but 2 cannot feed 3 every well or evenly/equally The Engine is pretty much a crank-rated 140, or a prop-rated 115, cut in half, except...

    Is this a long shaft on a short transom and other questions

    Lower the motor, and see where the AV Plate is in relation to the Hull Bottom. From what I can see in the pic, I feel confident that both are 20 inches

    That would certainly give the trailer, suspension and frame, a run for its money

    Boat with engine ($500 update)

    Years of Evergreen Needles will have softened the Floor under any Carpet, and all the snow should mean the boat gets rinsed every spring thaw

    Why Oil Injection?

    OMC didn't market their own TCW Oil until about 66 or 67. Prior to that the manuals stated using Outboard Oil or Non-detergent SAE 30 at 50:1. OMD later put out a Bulletin stating that their Branded Oil could be used in all engines at 50:1. I wasn't scared about using it in our 1957 35hp and our...
