    4.3 no power to fuel pump

    How did you try and suck gas from the fuel line? If it was your mouth I would guess you don't have enough suction.

    4.3 no power to fuel pump

    A typical internally regulated alternator has a smallish wire for sense (always has voltage). Another smallish wire provides voltage for excite (key on). And a large wire for alternator output. And ground via the case.

    Help water leaking

    I agree that the engine probably needs to come out. Contrary to the popular name of "freeze out plugs" they are actually casting plugs. They are not there to prevent a cracked block when not properly winterized. But you may get lucky. Once the engine is restarted you need to check for milky oil.

    SX-A, Drive will not turn prop

    The drive needs to come off regardless. Once off you can check things out better. Check for metal in gear oil.

    Catastrophic Engine Electronic Failure?!? Diagnosis Help!

    People can complain all they want about the engine electronics and EFI and the cost of a Diacom. But I had a 1987 Mercruiser 5.7 L with carb and electronic ignition. And now a 2012 VP 5.7L with an ECM, EFI, etc. The 2012 starts and purrs like a kitten. Significantly better starting and...

    Catastrophic Engine Electronic Failure?!? Diagnosis Help!

    Your either going to buy the Diacom to scan the engine codes now or latter. If your going to DIY maintain your engine you need a Diacom.

    FWC V8-300-C-A

    If you fill the reservoir to the very top when the engine is cold and then run the engine until its at operating temperature the coolant will expand but there is no place for it to go to so what happens?

    FWC V8-300-C-A

    So what happens if one full the level up to the very top of the reservoir and screws the cap on and gets the engine to it's normal operating temp?

    FWC V8-300-C-A

    This is a new to me boat. When I bought the boat the FWC was low on coolant and it took a few tries to get the cooling system filled with coolant and get the air out of the cooling system. Then while running the engine as a final test before an actual run in the water and a hose blew off where...

    Removing impeller

    The small O-ring at 12 o'clock is a keeper for the bolt. They go on the the bolt after the front cover to prevent the bolts from falling out of the front cover and into the bilge and never to be seen again.

    Overheating during cruising but normal under idle

    You need to see if it happens again. Could be something as simple as you picked up a plastic bag on the outdrive water intake and when you slowed down the plastic bag got free. An IR thermometer gun will help you figure out which part is actually overheating. What year? I don't suppose you...

    4.3 Gl over heat

    An IR thermometer gun you can point at various engine and cooling system parts is a good idea for $30 or so..

    4.3 Gl over heat

    Is it FWC or RWC? You need a Diacom to tell you why the alarm sounded.

    2003 Crownline initial starting problem

    So after starting does it idle fine? Run OK with boat on a plane? What about turning off the engine and starting it 5 min later? So the next time after the boat has been sitting overnight at least pull a couple of plugs and see what they look like. I do not believe pumping the throttle does...

    First time pulling an engine questions

    Helps to have a friend with an excavator to pull the engine. Irwin sells a ez-out kit with left handed drill bits and matching ez-outs. Some might weld on a nut to the broken off bolt to try and get it out. I still vote for a new oil pan

    2005 vp gxi turns over, won't start

    The battery is a simple thing to charge and test. Make sure your starting battery is up to snuff if it's questionable.

    Injectors

    Go to Bob is the Oil Guy forum and contact Trav. He is one of the best and specializes in gas engine injectors. I bought a set of multi port injectors for a Jeep Grand Cherokee to replace the stock single port injectors from him.

    Fuel in oil, how many oil changes should I do?

    I would not go crazy with several oil changes. The fuel will tend to "burn" off when the engine gets hot.

    2005 vp gxi turns over, won't start

    If you have a decent spark then a shot of starter fluid should get it to run for a few seconds. Why the weak spark? Look at solving that issue. Low compression will not cause a no start condition. Unless it's no compression. If the engine ran recently it's doubtful the compression has...
