    Volvo Penta 3.0L beeping

    remove the wire from the switch, either held in place by a nut on the switch post or a spade terminal nothing will cause the alarm to sound if you disconnect them, the switches complete the audio warning horn circuit to ground. remove the wire from the switch and the circuit is open

    2000 merc 5.0l alpha one gen two

    as AD stated the lube monitor is normally open, as is the oil pressure switch and the temp switch. all three switches close when the threshold is breached and complete the warning horn circuit to ground, thus the horn sounds seeing as how you haven't replaced the IAT which you noted does have a...

    4.3 thermostat

    agree with the comprehensive list scott mentioned, would add increased fuel consumption but may not be easily noticed being its a boat, fuel economy is the last item most boat owners are concerned about. are you have issues with the cooling system not working properly?

    3.0 Stumbles/Bogs

    low end would be about 4 psi at idle and should see a steady psi throughout the rpm range of 6-7 psi. if the gauge is rapidly bouncing between two limits it can indicate a failing diaphragm. vacuum should be no more than 2 in/hg, anything higher would indicate a restriction between the fuel...

    3.0 Stumbles/Bogs

    possibly one or both of these can be an issue. with adding the separator its possible the fuel vacuum has breached the threshold of no more than 2 in/hg. it may be that the fuel pump prior to the addition of the filter could have already been close to the spec of allowable vacuum. adjusting the...

    Bravo 1 whining noise at 3000 rpm

    given the boat is a 2013 vintage there's the possibility the gimbal housing does not have a grease zirk for the gimbal bearing. this is right around the time mercury went to the "permalube" style gimbal bearing which is non-servicable meaning one cannot add grease to it that said, seeing as how...

    Volvo Penta 3.0L beeping

    a carbureted vovlo of that era should have only temp and oil pressure audio warning systems. the system relies on switches for both temp and oil pressure. even though the gauges are reading correctly doesn't mean that either switch has failed or there is an actual issue when it happens again...

    2013 monterey 204 fsx prop not operating

    this would indicate that there is less chance of anything internal being damaged but does not rule it out completely. again, with the twisted splines on the propshaft as undisputable evidence of some damage, you cannot rule out internal damage without further investigation, e.g. disassembling...

    2013 monterey 204 fsx prop not operating

    looking at a rubber hub in a prop does not rule out that it has failed, with the prop slid on the shaft and the drive in gear (engine not running) try rotating the prop against the resistance of the shaft. if the prop rotates but the shaft is stationary then the hub has failed. it is merely...

    2013 monterey 204 fsx prop not operating

    the engine has nothing to do with shifting into or out of gear, the only transference of power from the engine is through the engine coupler the troubleshooting outlined in previous posts regarding the propeller hub and shaft would require the boat to be out of the water, and running the engine...

    PCM no spark! HELP

    all the sensors on the engine use a 5 volt reference, not 12. the voltage you are seeing at the cps is correct. the reason for 5 volts is because the ecm provides the voltage and anything above 5 volts can cause internal damage to the ecm. do not apply 12 volts to the sensor its possible that...

    2000 merc 5.0l alpha one gen two

    two beeps every ten seconds indicates a "non-severe" fault is the gear lube monitor full? sometimes the float gets stuck and will trigger the alarm, you can disconnect one of the two wires coming from it with the key off, then turn key to the "run" position to see if it goes away otherwise...

    2009 Sea Ray 185 4.3 TKS - a few questions.

    that is the proper way to connect wires in a marine environment, best option is solder and heat shrink but heat shrink butt connectors are nmma/coast guard compliant not scotch locks, not regular butt connectors, and definitely not wire nuts i'm not keen on automotive ignition systems but MSD...
