    2012 Tige RZ4 Loud Vdrive

    I am the new owner of a 2012 Tige RZ4. The Vdrive seems loud in my opinion to me. I had a 2006 20V Mp 340. It’s kind of a loud hum or whine noise the moment you put in drive and goes away in nuetral. Any possible input would be appreciated.

    What is your engine and v drive configuration?? I forgot what years got what....if it's a ZF 45IV they are just notoriously noisy in my experience.

      I have the PCM 409 motor…I’ll take a pic after work…I’m not certain what VDrive it is

        That will be a velvet drove "Power Plus" probably a 1.56 ratio (will be on the tag). The dipsticks need a 3/8 open end wrench to check. I'd start by checking fluid levels. Normally they are pretty quiet except for the standard whine in reverse that comes from Trans not vdrive.

        Have seen a few output seal fail on them and leak. Other thing is people don't get the cooler drained and it's cracks and makes milkshake in the box and wipes it out.

          well, my transmission is shot, yeah me, have been quoted thru Texas Tige to have a new one drop shipped to me $2717 to my door and will be pulling the triggervery soon. Being this is a new to me boat any maintenance things I should do while I am there replacing the transmission during the off season? I found a great write up on another forum to use as a guide on replacing the tranny. I appreciate any and all advice.

            I'd call Harbor Marine in Washington and price a refurbished Trans from them or possibly just sending yours to them for rebuild over winter. I'd consider doing the flex plate and a Glide shaft seal while it's apart. Also the Trans is what the rear engine mounts bolt to so you will have to block up the oil pan if you don't pull the whole show out.
