I have a 1988 Chaparral 187XL with a 4.3L Mercruiser. I am trying to find out some specifications on the boat. How would I go about doing that? I tried calling chaparral, but they only support the newer models. <br /><br />I'd like to find out the range of the boat, fuel capacity, oil to use, and other general maintenance requirements. <br /><br />Thanks for any assistance!
