Looking into installing digital gauges on the dash. port temp dial fluctuates (maybe bad ground)and the stbd reads Hi. I already changed out the senders. John Bensen said get the ohm reading on the senders and match the VDO digital gauge, that matches the sender. He said maybe Speedo tach is out of business. Anyone hear if they shut down or moved and or who would be the VDO reps in San Diego. Those guys were good at answering the questions on gauges. Just changed out main bilge pump and bothfrwrd and stern float assemblies, bilge breaker and all the wiring. New bilge switches replaced. They are a hair bigger so had to file out the previous cut outs. Hot weather has sure helped me to lose some excess pounds. Hopefully take out the boat again this weak for an other shake down. John said the engines should run at 180. I thought they were running at 205. All water stuff has been changed, rotted out etc. Not sure what would cause th estbd engine to overheat or run hot at WOT. Old engines, I dont rung them over 3200. Work fine at that speed. Some people say I should open a deisel up once in awhile to blows out carbon, etc.
