    Volvo Penta 5.7 no spark

    Your seeing fuel on the spark plugs so the injectors are firing, no need for NOID light. Any chance you gotten some bad fuel? Have you checked fuel pressure? Does look like its no spark You have power to the coil, distributor cap is new, need to scan motor to see if there are any codes.

    Water Leaking from sides of stern drive help

    Plug is out and there is no water in the bilge, yet water is leaking around the housing? If above statement is true then no this isn't normal. Bounce on the drive real hard to see if transom flexes. If it does, then transom is soft

    Volvo Penta 5.7 no spark

    Don't know what it is other then the ECM is seeing a fault. A scanner will indicate which it is. Could be as simple Battery voltage going to low, or more complex like another sensor or ECM Your seeing fuel on the plugs then the injectors are firing.

    Volvo Penta 5.7 no spark

    Gauges are analog and showing 20 when engine is off just means it probably needs replaced. That said seeing 20 when off and 80 when running would tell me its about 60 when running which would be closer to accurate, and is good enough The diacom software would be best because it can record data...

    Check your battery voltage, should be close to 12.7V at rest and not connected to a charger. Voltage should not drop below 10V when cranking Has the distributor been moved? hope not

    Volvo Penta 5.7 no spark

    Your correct it comes from the crank sensor I would start by replacing the distributor cap and rotor. Most call them Crap cap because they can look great and be bad. Most carry a spare because there is no warning when they can go out With the new motors pulling the coil wire can cause their...

    Volvo Penta 5.7 no spark

    Does look like there was a change with diagnostics connector between those 2 years. Find the connector near the ECM and see if its round 94024 or flat 94029. It will have a plastic cover over it

    Volvo Penta 5.7 no spark

    The Tach signal comes from the distributor. With the new motors they really need to be scanned for codes. Scanner can be bought from Rinda https://www.rinda.com/marine/marinemenu.htm What was the motor doing before this happened? Have you checked fuel pressure at the rail? How are you checking...

    mercruiser alarm

    Don't see a real tight belt causing an alarm on anything. Over time it will burn out a bearing, but not cause a water pressure alarm. See it as coincidence. As Q mentioned the water pressure sensor has the highest failure rate If your new motors are closed cooled then may have air in the...

    1991 Mercruiser 4.3 …Have power but will not crank.

    If you jumped from the small terminal on the inside closest to the block and the starter post then either the starter has an issue or the motor is locked up Find your slave relay on top the motor. Jump across the top larger terminals and see if it will crank

    Chap said Note there are only 2 Bat switches. One for motors and one for house and they are on starboard side AFT door. The isolator is on port side transom Looks like I'll be unbolting things and have a look

    Maybe my turn for new boat time

    Don't have a Pic but looks just like the one I removed from the formula, just 2 bank and not 3 Call mercury and tech said the isolator will not be an issue with the motors. Might replace with ACR anyway, less chance of over charging. It came with lead acid Bats so they will be leaving in...

    Maybe my turn for new boat time

    Just called Chap and they don't give out that information. REALLY Would provide info on certain areas of concern, so I asked about the Isolator. Now I wait
