BEEP CODES — the 4 maintenance items that can trigger the beeper are:

• High engine water temperature (>203*)
• Low oil pressure switch (<6 PSI at switch; NOT dash gauge/pressure sending unit)
• High transmission temperature (>140?*)
• A diagnostics trouble code

Sorry, I may have given you bad advice on the knock sensor.  Removing the transmission temp and oil pressure sensor will stop the beeping if those are bad, (which I would do next to eliminate as possibilities) but removing knock sensor may trigger the same alarm just as if it was bad, so I believe that may still be the culprit. 

You could try disconnecting the transmission temp sensor and oil pressure sensor next to see if one of them is failing.  Next step would be reading the code that it's throwing...it could be lots of things like TPS sensor, etc.  I'll try to remember to put my old code reader in my tool kit to lend you if I see you out there again. 

Ben good to meet you last weekend.

See my response below on what I found

Is it the same beep when you turn the key on but don't start the boat, or a different beep?

If it's the same beep as when you key on but don't start, try disconnecting the wire from the oil pressure switch and see if it goes away.  If it does, replace that.  They're cheap, easy to replace, and go bad.

Yes it’s the same beep.  

Thanks guys. I did some inspecting today and noticed a corroded oil pressure switch that was completely detached. Right near the oil filter.  I re-wired it and will see tomorrow if it fixes the problem when we launch. If you have any other suggestions, let me know. I will respond when we test drive tomorrow. 

It looks like this with the cover.

Here is one without the cover.

Might as well make sure all of the cable connection nuts are tight while you are in there.
