They said the oil pressure sensor is bad. I have another one sitting on my dresser at home but I’m trying to confirm which one they are talking about. The one that connects to the blue and brown wire just below the exhaust manifold on the port side that’s skinny or the short “fat” one that...
First: they said the oil pressure was within spec on the boat gauge and manual gauge and engine runs great.
Second: they might not have filled up the fluids other than the oil when they tested it as they were confirming the harness work so I’ll bring that up to them. They don’t have techs that...
They tested the oil pressure with it running and it’s within spec, it’s just the alarm. Since my insurance company requires no alarm mechanisms activated, they have to get the alarm to stop.
Both were complete Mercruiser engines, only thing missing was the connector from engine to hull. Both carbureted. Original serial is 1A066831 and new is 1G415169. Nothing from the original engine was saved
The shop is working on getting my new to me motor installed (2019 Mercruiser 4.3) and is having an oil pressure alarm issue. The original motor was a TKS and it’s being replaced with an engine without TKS (bought the engine with 5 verified hours for $1600 instead of $11,000 from mainland). The...
Well, I finally got the answers to why it wouldn’t start. Water intrusion in cylinder three from a failed exhaust manifold. I found a reman locally for $1600 and had it inspected, new exhaust manifolds and installed and they finished up this morning. Still have to diagnose a tilt/trim issue but...
It uses the existing coil wire. It’s the in-line style. The plugs and plug wires are new. I replaced them when I put the Delco EST ignition system in last month. What I find is weird is that there’s no power to the purple wire for the fuel pump but there’s power everywhere else along that wire.
However, when I use a spark tester, i get a steady blue spark. I started testing some of the wires and tracing them, and I’m not getting any power on the purple wire at the plug to the fuel pump.
Gauge is only maxed out with key on. I inspected the harness and there’s no corrosion at the 10-pin plug, and all the female connections look good. I do own a timing light
