1) Muffler - screw on the bottom drains that water
2) Heater and/or Shower - most boats did not have them.
3) Two Water Pump Hoses and J-Hose - pulling the hoses and putting them facing the bilge to get the water out
4) Crossover hose for water in the the exhaust manifolds
5) V-Drive hoses or brass plugs
6) Block Plugs (brass) on the bottom of engine - one on each side
7) Ballast bag/lines to pumps.
