    Help Aq271 no spark

    The prestolite distributor is just a points type. The points need to open and close as the rotor turns. If they are not doing that then adjust so they do. Make sure the coil has 12V while cranking. Once it starts it would have about 9V If they are operating correctly, then may need the...

    2000 Four Winns H170 with Volvo 3.0 - Engine removal necessary?

    The stuttering would indicate it needs a carb rebuild The noise does sound like the starter. Being a 3.0 there should be room to get at the bolts. The issue may be the design of the boat. Are there any panels/seats which can be unbolted? If not then its the boat that causes the problem...

    383 strokes conversion.

    With rpm showing then the ECM knows the distributor is firing and should be firing the injectors. Listing from the ECM are within spec so it should run. The injector test error your getting is the only clue why it won't run. Suggest contacting John at https://www.boatunlimited.com/ to see...

    Crusader 454 Cooling

    Had a 50/50 chance on front to rear mount HX, oh well With both motors doing the same, then I'm thinking its normal The motor temp is correct, mans higher. The circulating water pump is the only thing that can make a difference in heat, and if it wasn't working right the motor would have an...

    Understand, but the oil pressure switch turns the fuel pump off if oil pressure is low, otherwise during starting, it comes from the starter post

    Engine Dies When Hot

    Without a serial number and being a 2003, would it be a Carb? If it is a carb motor then jumping the fuel pump should have no effect Most likely a TBV ignition Something is getting hot like the the ignition module. If it is a TBV, when it won't start, and before doing anything else run...

    Penta 3.0 GS overheating, U-Shaped hose pressure.

    Being a SX it doesn't have the piece I was thinking about. Yours has a tube (item 62) and its not mounted on the top like the older ones I was thinking about. It does use a plastic fitting (item 18) which is known for cracking. The clear hose would show it this is the issue with bubbles...
