@@ProWrenching than YOU for be always willing to help !!
Just want to say hello. Thanks for your videos I have the same mercruiser 260 you have helped me a bunch.. the problem I have is finding the correct parts.. it would be a great help if you could give us part numbers for the items... I need a water send and oil pressure.
Fantastic video, super quick and clear!
Thank you!
So i know this question doesn't pertain to this video but where would one order a alternator and belt for this same engine?
Try marineengine.com. You can look up the parts using the model and serial number of your engine.
So when you test the oil pressure sending unit by disconnecting the lead (should show zero on the gauge) and then ground it (should peg out high on the gauge) does this indicate that it's good or bad?
This is a test to verify that your gauge is working and that you need to test the sending unit. It shows that it’s working
@Pro Wrenching That's what I thought, but I just wanted to confirm. I'm still learning about electricity. THANKS!
Question, do I need to have the ignition run for this test ?
@@zaratrustraxss the key needs to be in the “on” position for the gauges to work so you can do the test. Key on, engine off.
@@ProWrenching thanks!
how do you actually test the audible alarm/buzzer to se if all sensors individually actually work?
The information below is how to test the audio alarm system. My boat is old and just has the gauges no warning buzzer. So you just have to keep an eye on your gauges.
Turn the ignition switch to the RUN position but do not start the engine. The horn should sound within 7-14 seconds.
If the horn didn't go make any sound, connect jumper wires between terminal A and the positive battery terminal, and a jumper between terminal B and a good ground. If the horn doesn't sound, replace the system. If the horn does sound, go to the next step.
Now connect a jumper wire from the end of lead C to the positive battery terminal, and a jumper from the end of lead D (tan/blue wire) to a good ground. If the horn sounds within 7-14 seconds, you"ve got a problem with the tan/blue wire running back to the engine (or some other switch).
what was the part number of that sensor 230 ohm please
Part #18-5899 is the Sierra part number
Do you happen to know what alternator is in it?
