    Re: Trolling motor cuts off in higher speed

    Do you have an inline relay? Most electric motors do. At full load the motor may draw too many amps for the relay. It trips and then cools down and self resets. You may have a weak relay that needs...
  2. Re: Anyone familiar with Mercury's (VW) 4.2 TDI engines

    As with all electronic engines, you probably have to use a Mercury dealer mechanic for any issue with sensors and timing. Test equipment is probably proprietary. It's not a stock car engine with...
  3. Re: Every flange and joint in my boat has fine white crystals growing

    Probably galvanic corrosion with the salt water acting as the electrolyte. Your zincs need to be in contact will all the metal in your salt water system. For example, the engines should have zincs in...

    Re: Can you make your own injector lines?

    If there is an industrial or farm version of the engine, then that would be a cheaper place to buy lines. Yes you can make new lines. The length isn't that critical. Think of the tube filled with a...

    Could be like vapor lock. Don't know your engine, but on other engines, I've seen fuel rails overheat when a hot engine is stopped and it causes the fuel to boil, forcing fuel into the return and...

    Re: engine stop solonoid keeps going bad

    Low voltage. In a lot of boat the 12v path to the solenoid is from the battery to the helm and back to the engine. If the path is long. the solenoid is probably not getting 12v. This causes the...
  10. Re: 671 engine, oil in coolant - diagnosis help request

    The heat exchanger is shared by raw water and coolant. In the event of a leak, coolant is under higher pressure than the raw water, so coolant would leak into the raw water. And It wouldn't put...
  11. Re: 671 engine, oil in coolant - diagnosis help request

    The heat exchanger is the usual cause. I'd call the shop and ask if they did a pressure test. Less likely is a cracked head/block, bad head gasket. But since you're also loosing coolant, it looks a...

    Re: 3YM30 cuttiing out at sea

    Probably debris in the tank momentarily blocking the pickup. I doubt the exhaust being under water is the cause. Military and some yachts exhaust underwater to limit noise. Since it was just...
  13. Re: minnkota intermittently turns off on off on when in 4th or 5th gear

    I don't know your model, but the circuit breaker is easy to trip when running flat out for extended periods on some motors. I don't know where the circuit board is, I suppose inside the housing. But...
  14. Re: minnkota intermittently turns off on off on when in 4th or 5th gear

    Do you have a automatic circuit breaker in line? Also look at the circuit board for signs of burning or overheat.

    I've used Detroits most of my life, about 60 years. They're the only engine of it's size I will use on the ocean. But good engines or not, you need to have a mechanical survey by a real Detroit...

    Re: Starting problems

    The solenoid disk and contact points have bad spots. The contact points go to the battery cable or the starter. When you energize the solenoid a copper disk that spans the two contacts, moves to...

    Re: Water draining from radiator on perkins 4108

    Depending the type of thermostat, it may block some, or most of the air from leaving the engine when it's filled. That's why some thermostats come with a small hole in the plate. It allows the air...

    Re: Water draining from radiator on perkins 4108

    Are you calling the heat exchanger the radiator or do you really have a radiator? Is the 4108 in a tractor?
    Sometimes the thermostat will keep the engine from filling with water and an overheat...

    Re: Mercruiser 7.3 V8 Turbo Diesel.

    I think that is the same engine in Ford F-250 trucks from 1997 to 2003. I have one in a truck. Usually when they stop suddenly it's one of the many electronic parts. The injectors work by high...
