    Is it worth the work 66 Evinrude 15hp

    Think I would still be on the lookout for a '57 or '58 35 while working on your '55 25.

    1958 35 hp Big Twin needle valves

    The guide/gland nut screw into the carb housing; the needle screws into the guide. Hold the guide in place while loosening and screwing out the needle. Make sure there isn't an extra needle valve bushing up in there by the point of the needle. System does work.

    Replace stop button with kill switch

    My 9.9 kill switches are two pole switches with black to ground on one side, and black to the power pack on the other side. The power pack connection is via a connector with (I believe) a striped wire going to the pack. Pressing the button completes the circuit, shorting the ignition. The...

    1988 Johnson VRO overheating alarm - help

    The typical advice on overheating is that 160F or more is the danger range. Get an infrared gun and check operating temps at the top of the heads. Ocean running (salt) or river running (sand) has special risks. You might consider removing the lower unit, and pumping hose water up the tube...

    1980 johnson 9.9 bogs down when trying to go to full throttle.

    120psi or a little less. It's possible you have an exhaust blockage. Drop the l.u and shine a light up to see if there is something that doesn't belong -- like a mouse nest. While there, check the foot for grass or mud for intake blockages.

    Only Running on One Cylinder

    https://www.oldoutboard.com/video-page I think the ohm reading for the for the secondary side (plug wire side) is a bit weak. Recalling from the Penn instructions, you should see 4 to 6 in a good coil with the tester set at 1K ohms. (Check the link. Hopefully, the reformulation still...

    Johnson 9.5 Weak Spark

    9.5s are not my specialty, but I think you need to remove the ignition plate to connect from the bottom. Insure the spike is contacting the inner wire (assuming you are using 7mm solid core wires). Following that exercise, set the coil in place making sure the coil mounts are perfectly flush...

    1958 35 hp Big Twin needle valves

    The needles should be tight enough that they do not rattle loose, but not so tight that you cannot adjust using the knobs. That means the knobs must be tight to the needles (poss. stripped screws if they remain loose). The needles are snugged up with the jam nut -- use a couple of cork...

    1988 Johnson VRO overheating alarm - help

    Sand in the t.stat means sand might be anywhere in the cooling system. I would remove the heads and clean out the passages around the cylinders.

    Float bowl pin stuck???

    Reference is to the pin in the float arm? Lightly tap it out with a punch, alternating ends. A spray of carb cleaner might be useful.
