I own a twin rig Hydrodyne used for show skiing. I have had terrible luck with my local marina. I paid way too much for a lower unit (port) this summer. About 2200 for a counter rotating unit - with shipping and installation it came to about 3K. I might add this unit had a one year warranty. Now I found Sterndrive.cc and service was great. Got the unit for half what my marina wanted to charge, and it has a longer warranty. I could not be happier. YOU GUYS ROCK.
