    hello, every body, I am grant from comfort diesel power limited. currently we are develop our Isuzu 2.8 TDI engine for marine, I have got a heat exchanger from Bowman, now I need comments for the impeller pump. could anyone give me some comments? For which model of the sea water pump I should use, or some specification for the water pump?
    I have just finished our conversion for cummins 4 and 6 cylinder engines, 130-350HP engine. they are successful, because you always request the low height engines. If you interested, can veiw our link www.comfortdiesel.com
    ;)

    Hello Grant,

    Did you look at my photos ? They show all the marine conversion I did on the 4JB1-TC engine. I machined an alloy adapter plate to bolt to the front lower pulley ( end of crankshaft ) and bolted the Jabsco pump to the alloy plate. I used the 1" Jabsco pump from my old engine, 5.0 litre V8. I think Bowman suggest that a 3/4" pump is OK, but my 1" one works well, and gives plenty of cooling water for the intercooler.

    I did keep the standard Isuzu oil cooler on the engine, this is cooled by the internal engine water, and does not cool the oil enough. I am going to fit a marine type oil cooler in the circuit from the Jabsco pump, as this colder water will cool the oil better.

    I am happy to help with any other questions you have. Do you possibly have a power output curve diagram for this engine, as I am trying to work out the best gear ratio and propeller size ?

    Regards, Paul

    Thanks Paul for your help, so now you are using 1" impeller pump from Bowman? If you have the photo for the pump, could you send me one? I want to check with the installing. my email is info@comfortdiesel.com.

    I am pretty sure that the 2.8l 200hp CMD diesel is the Isuzu 2.8. Check what the specification sheets say their pump is.

    hi, ali, for Isuzu 2.8 TDI engine, we have already build it out, the output is 98HP, the CMD engine you are talking about is diesel or gasoline type?
