    Default Navy barge engines 8V-71TI engines 1994

    Hello , first post. I have 4 Detroit Diesel engines, 8V- 71TI . I have been reading up on them and have conflicting information. The specs from the manufacturer say the have 600 hp each. They each run a 360 degree jet propulsion system. They were built for Navy barges. I have always heard that the hp was closer to 325 - 425. Could these have 600hp each? Any info would be helpful. They were built in 1994. They have about 1400 hours each. Thanks

    I believe the 8V71 with turbo is easily capable of producing 600hp. I have seen custom bus installations rated at 500hp. I have some old on highway manuals that I can look through to see which injectors would get you "up there" although 500hp is likely as close as those publications go.

    450 is about right. At max hp about 3000 hours with good care and a good operator. Running below 80% of hp, as much as 7000 hours. I've seen 8v71s with twin turbos, don't know the hp, but could be 600. Used a lot of fuel. Short life at that hp. High exhaust gas temperatures is what limits life. If you really need 600 hp, you'd be better off with 12-71s running at 2/3 hp for long life.
