  1. Re: Tamd41b temperature gauge not reading properly

    Hummmm...that won't happen from a marginal wire to the sender....I don't believe there are any popular gauges that can be field calibrated...If you have another engine, you can usually swap gauges...
  2. Re: Tamd41b temperature gauge not reading properly

    which way is the gauge 'off'?
  3. Re: older 4 cylinder mercruiser Identification?

    The manual covering the mid-late 1980's inline four cylinders shows a timing curve consistent with the data provided in Post #6, for the Delco distributor. The Prestolite distributor curves, in the...

    Re: Need relacement crusader 454s

  8. Re: older 4 cylinder mercruiser Identification?

    Manual Number 1 covers those engines made in the 1960's....it states initial timing is 8 deg BTDC, except for those engines using distributor #1112467, which use 6 deg.

    Re: Yet more 7.4L Raw Water pump issues
