The engine drives a Borg Warner Velvet Drive transmission which in turn drives a Max Prop which is self feathering and reverses the three blades when in reverse for more reverse power. The engine exhaust is fed to a fiberglass water lift muffler in the engine room, then feeds an expansion muffler at the transom which reduces the possibility of sea water entering the engine through the exhaust system. Under the engine is a full fiberglass pan to catch oil so it can't get in the bilge. The main bilge sump is in the engine room below the prop shaft. There is a high capacity electric bilge pump with automatic water level sensing. The manual switch for the Nilson vertical hydraulic anchor windlass is just inside the engine room door for easy access. The hydraulic pump is mounted on top of the engine and belt driven. The engine room is sound proofed. The one gallon per stroke Edson manual bilge pump mounted on it's board is stored in the engine room. The quick connect hose is under the floorboards amidships. One 70 gallon aluminum diesel fuel tank is in the engine room, the other in the starboard walk through. One set of two six volt batteries is in the engine room and the other set opposite in the starboard walk through. The main electric terminal panel is in the engine room also.
