I have listed for sale a pair of Arneson surface drive setups.  They are ASD 8's.  They include the steering rams, tilt rams and a tie bar as well as the props. I am willing to separate for the right offer.  These came out of a friends boat yard. I assisted him in recovering the vessel after it sank in the marina . The vessel was reported to be in operational condition before it unfortunately sank.  There is a tear in one of the CV boots but there does not appear to be any corrosion or marine growth inside of it. Both units turn freely by hand.  Props are 24x25 Nibral.  I will ship at purchasers cost or I am available for pickup in NE Florida. There is no warranty or guarantee of operational condition.
