Bob Tail Conversions...
A "bobtail" conversion is an automotive motor converted to marine
use that does not have a marine transmission. Such a motor would be used on vee
drive drive installations that incorporate the transmission in the vee drive, a
stern drive that includes forward, neutral, and reverse, or a jet drive
installation. These conversions come complete with all the necessary items to
replace the existing automotive parts to adapt it to marine use. Bobtail
conversions are available with either elbows or risers. Risers are used in
deep-vee, jet drive, or other boats where there is the possibility of water
backing up into the manifolds. The contents of the kits are noted. All castings
such as motor mounts, manifolds, elbows, and risers are cast from aluminum and
highly polished. Associated parts are chrome plated where applicable.
