    Control box???

    OK, motor end of cable.... blue is trim up, green is trim down. They should plug into Y connectors on the motor trim switch. Brown is temp alarm and other brown is temp gauge. Most controls have a built in buzzer for over temp. Turn the key on (power connected), and ground each of the brown...

    Vintage Mercruiser Tach Pole Question

    The real old tachs (1973 and earlier) had only 2 connections. One would go to the switchbox, and the other was likely ground, however, you had best find some real old wiring diagrams to make sure.

    Actually, the swelled cover only affected reverse on my motor. Forward worked fine. Not sure why that was, but it was.... The forward part of the rod may have been more worn down? Arch, make sure to measure the length of the shift rod, in neutral, offset facing forward. Measure from tip of...

    U-Joints for 2003 Alpha One Gen 2

    When I replaced my U joints (Alpha 1 Gen 1), I took them to my local auto parts store. They matched them up, real easily. The replacements were the same external fit and function, but the bearings and races were internally different, however, they were less than $10 each and the MerCruiser...

    Outboard won't spin unless spark plugs removed.

    Check the starter wiring for dirty connections or rotted wiring. If most of the battery cable is rotted away, the starter can spin fast and then slow down rapidly, like the battery is bad.

    Miss marked prop?

    Clearly those are different style props. Not sure what else I can say. The total surface of the prop blades looks close, but the rake of the new prop seems a lot greater. Obviously the pitch of the new prop looks to be greater. Is it possible the original prop is not marked correctly or...

    1994 OceanPro 150 lost reverse, sort of

    Take a look at where the shift lever goes thru the gearcase surface. Many of those have a shift cover that will swell and grab the shift rod. It makes getting into reverse very hard. The cure is a new shift cover.

    Points

    a web site like crowleymarine will have the part number. I would expect the points would be available at a lot of places. A search on the part number should turn up some choices.

    Miss marked prop?

    Put the props side by side on the bench. Use a ruler to measure the blades from the bench fore and aft. You should be able to see a difference in the "twist" of the blade. Also measure diameter, as that affects performance. Make sure the hub is the same size.
