Re: 410 Sundancer/Express Cruiser and 400 Sundancer/Express Cruiser **Official Thread
My port oil pressure is also at zero with the mechanical gauges showing perfect pressure. This must be a common issue. You say you replaced the sending unit? Have you checked the gauge itself? I am thinking about swapping sides on the gauges to see if the port side is bad.
FW is always welcome! But, certain 480DB owners are not allowed here.....he knows who......I mean.... they know who they are.

I can't help with your Fuel Guage issue but I have had a similar issue with my port side Oil Pressure guage. I nearly had a heart attack two seasons ago when I was just getting ready to exit a local inlet in heavy traffic (Shark River Inlet between the bridges for you local guys) and the port oil pressure dropped to zero. I IMMEDIATELY shut down that motor and raised the hatch for a look-see. I was expecting to see oil everywhere but I was very relieved to see my bilge nice and clean. The admiral was at the helm (ALL NERVOUS) and I had her restart the port motor with instructions to be ready to shut her right back down. (This is for diesel powered 410DAs...nothing for you critter turd eatin' Virginny boys to see here) and I had my eyeballs focused on the motor top mounted mechanical oil pressure guage. It was like a ray of sunshine to see full pressure on the ER guage and zero on the electric dash mounted guage. I jumped back up to the helm and had a safe trip home.
Then, I had to diagnose the issue with the helm guage. Turns out it was a simple oil pressure sending unit. HOWEVER....I have yet to be able to get the two dash mounted guages to read the same. AND...every so often, only when I bump the throttles from idle, the pressure on the port side helm guage will jump to zero and back....like I turned a swithc on and off. I've swapped the sending units...bought two new ones...and that port oil pressure reading at the helm just has an issue. There must be some kind of intermittent short somewhere between the sending unit and the helm...but I haven't been able to locate or rectify.
