I wonder why my water pressure is so low then? Might need to attempt a back flush for the Hell of it. Maybe I should just replace the impeller too? Keep the one in it now as a spare if still good.

What's a good way to back flush?

As for the wiring pin connections, not sure how you'd inspect those?

This is what I'm thinking too. Might be my built-in depth
gauge as you suggest.

Thinking back, I had an issue with my tach acting weird after the GF and I made a top speed run with the old engine last year. Figured it was old and on it's way out. The gauges were dated, so I replaced them and my dash panels over the winter. Maybe it wasn't the old tach failing, but the original wiring causing the problem?

The boat is a 1998 and has been fresh water all it's life. The previous owner was a schmuck and had/did some really questionable work on the boat. Looks like I need to do some detailed testing of my original wiring. Lucky me.....

Thanks guys

Pressure is increased by a restriction and/or more flow, the lack of any restriction means low pressure.
Back flushing is used to decrease the restriction so more flow can happen. If the raw water pump is not pumping correctly then there is low flow.

Understood. Thanks

I know this is an old thread but looks like the OP was just on here. Did you ever get this figured out?

Yes. There was another alarm under the dash for the water depth gauge. I think it was set on deep water notification. So it took a bit of running before it would activate, making me think it was an engine alarm.

Also another problem I came across is the factory wiring connectors (multi wire plastic quick-disconnects) are aging and making poor contact. The main 12V + was loose and making intermittent contact for my tach. .
