Barr is the OEM casting house for Edelbrock, Volvo Penta, Mercruiser and others.
GLM stands for Good Luck Marine.
Osco sold the casting business to Sierra. Name only, none of the equipment or talent
With that stated. OEM or Barr
I have a few cut-up plug sockets (similar to an O2 socket)
Also, unthread the wire spud. It gives you wrench clearance. Then thread the wire spud back on
Looks to be wired wrong (with the resistor on the wire going to the starter R terminal and not the wire going to the ignition switch
Or your battery is not up to snuff, and your coil isn't wired with a resistor
File the points, use a dwell meter to set the dwell. Then set timing.
If you can't get a dwell reading, your points need filing or the condenser is shorted
Service the points
they are just like the clocks in your house. after a month, they all read differently. if it really bothers you, keep the key on on the slow hour meter.
There are people that also like Ford Pintos and AMC Pacers, those people have a straight jacket
Tri-hull boats have 1 pro, and about 5000000000 entries in the con category
trim gauge is different range / style / signal
you no longer have tilt up/down with mercruiser
you could get the other senders and tach to work with some effort. however you will need to rewire everything
You can get brand new gauges that look like they were made in 1907 if you wanted...
