I am in the process of buying a 1978 21' Mako with an average condition hull. A lot of people say that in general, 1978 was a great year for Mako, but some say not to touch it because of the age. There are several issues with the boat: (1)the engine is for some reason mounted on a hydraulic jack plate that is inoperable - I want to have the jack plate removed and have the engine mounted directly on the transom; (2) the gas tanks are originals and are reportedly in satisfactory condition although it has been suggested to me to just go ahead and replace them; (3) the wiring is in bad condition and needs to be "redone". Can anyone give some thoughts on this purchase and these issues? How about pricing for this? Should the hull be priced based on NADA low retail/average retail? Where in that range should it fall assuming everything else is in decent shape including no wood/stringer rot and a gel coat in decent shape? Is there another way to come up with value?<br /><br />The boat has a 225 hp, 2001 EFI Saltwater Yamaha which gets at why I'm buying the boat: it has new power and a good hull with which I don't have to put up with depreciation the second I drive away with it.<br /><br />Your comments are appreciated.
