    1987 48 SPL Coils

    I'm still in the middle of doing a bunch of maintenance so I decided to do a basic check on both of my coils. Both were at 0 when checking the ground to the primary post. However, when I checked the ohms between the primary post and the secondary post, one gave a reading of 382 ohms and the...

    Instrument light on discontinued OMC Concept series tachometer.

    I am adding a few gauges to my 1987 48 SPL. I picked up some NOS speedo, volt, and tach gauges. I also decided to go with LED lights for the instruments.

    Redoing dash, Steering question.

    I want to redo my dash as it has seen better days. I have the old one off and am considering my options. The dash is rather small but I think it has just enough space for what I want. It originally only had the ignition, a navigation light switch, a speedometer in very rough condition and the...
