I have a 1994 volvo dp outdrive 1:78 and i am trying to replace the exhust and u joint bellows. I called the mfg regal boats they told me it is a drv 1:78 serial # 3102148476. I could not find any listing for a drv. I called volvo tech support they said it could be: Dpd dpe dpc. But they for some reason could not find what drive it was with the serial number, which is odd. I bought both bellows from a local dealer and we were both guessing at the model. I just spent $175.00 for both bellows (bend over) but before i "attemp" to take it down (and hopefully not have spare parts or broken parts) can you give me the correct part numbers for these bellows before i open the boxes and eat $175.00 of rubber. I have also read everything on the internet about how to change these bellows, but, i would like to see or read how to do this on the outdrive that i have before hand, any suggestions. If not, of course the marina will do it for the tune of $1500.00 to $2300.00 depending on which outdrive i have.
