    Default Volvo penta power issues

    Right let's see if anyone can help, we have a boat with 2 AD41D engines, one engine is fine, the other however will not rev over 1400rpm, we've had the turbo done, the injectors and injector pump done, the fuel polished, lines cleaned, ant ideas? At wits end! Thanks.

    I'd do a compression test. One or two cylinders might not be giving their share of power from a ring or valve problem. Could there be some intake air restriction the other engine doesn't have? I believe that engine has an aftercooler. It may need cleaning.
