  1. Re: Mty Detroit v12 600kw turbo diesel солярка в масле

    The fuel pump is mounted to the blower housing. It is driven by one of the rotors. The rotor bearing is lubricated by engine oil. If the fuel pump seal fails, pressurized fuel is sprayed into the...

    Re: water makers

    There are 12v, 24v, 48v, and Ac 120v and 220v watermakers. Mine is self made, but similar to what's found here: https://www.cruiserowaterandpower.com/piston-pump-water-makers/

    Re: ye ol 671 is smoking white when cold

    An injector shop can test your injectors and rebuild as necessary. No real need for a 2nd set. You could have worn tips. When the fine holes get bigger, some or all of the spray becomes large...

    Re: ye ol 671 is smoking white when cold

    White smoke could also be steam - water. But you would be loosing coolant. And that would be a head gasket failure, but not too common in marine Detroits unless they get hot.

    Re: ye ol 671 is smoking white when cold

    Depending on the model, the fuel pump pumps 35 gallons an hour or more. It's a gear pump and should blow out any debris that went thru 2 filters. I doubt you have a return line clog. The fuel is part...

    Re: It just stops....

    A breaker would stop all current to the motor. But a thermal protector could be in the motor or on the control board. Since the motor works again after sitting, I'm guessing it's a heat problem. I...

    Re: It just stops....

    Is there a self resetting breaker in the line? If so, it heats up from too many amps and trips. Then it has to cool down to reset. Or the controller or motor could have an thermal breaker.
    If the...

    Re: Perkins Prima 50hp water in engine

    Probably a leak in the heat exchanger. Most of the time, the oil pressure is higher than the raw water, so only a little water transfers at startup. You should see some oil loss and a sheen in the...

    Re: 12v71TI conversion question

    The best way to save fuel and increase life of a Detroit is go slower.
    Turbo Detroits have lower compression pistons than naturals. You'll have less power than you plan on.
    Turbos fail because of...

    The motor wasn't built by Sears, just the name plate.

  13. Re: Got a big boat and new to all this, need help figuring out what this tank leading to engine is f

    The fuel system is basically a closed system and should still be charged with fuel. I'd forgo changing fuel filters until after the engine has run. When you open the system, air needs to be bled out....
  14. Re: Got a big boat and new to all this, need help figuring out what this tank leading to engine is f

    Looks like an expansion tank for coolant. Usually you have a pressure cap that keeps the coolant under 7-15psi. This appears to just be open to the engine. I would use something more that straight...

    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...
  16. Re: Anyone familiar with Mercury's (VW) 4.2 TDI engines

    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...
