Victron multiplus → Transformer 240-120→AC panel

Shoretie→ Shoretie transformer→ Victron multiplus

Gen control panel→ ties to ACU and Victron multiplus

Question 8

Flow of the Fuel System

Answer 8

Hand primer before fuel pump then to secondary filter

Question 9

Flow of the L/O

Answer 9

Engine sump→ pump→ to turbo back to sump→ L/O cooler → filter back to cooler(in-between sample valves)→ pistons→ rocker arms and gear train then gravity falls back to the sump.

Question 10

Flow of the R/D gear L/O system

Answer 10

R/G sump→ pump→ R/G→ to the thermostat→ sump or → to the shell and tube cooler→ then back to the sump.

Question 11

Flow of the J/W system

Answer 11

J/W pump→ L/O cooler→ engine block→ head→ thermostat→ back to the pump or thermostat→ back to plate cooler→ back to the pump

Also hits the turbo and exhaust manifold then dumps to the thermostat.

Question 12

Flow of the Raw water system

Answer 12

Seachest→ valves→ strainers→ pump→ (shared gear train with the hydraulic pump)→ plate cooler→ splits off hits CAC then back to main line→ R/G cooler(shell/tube)→ deicing valve→ then muffler→ then → OVBD

Question 13

Flow of the Hydraulic System

Answer 13

09 gallon tank→ pump (shared gear train with raw water pump)→ DCV’s→ Bucket ram→ Steering ram→ Intercept ram→ Keel cooler→ filter→ tank

Question 14

Flow of the FM-200 system

Answer 14

Coxswain side Nitrogen bottle (1,800 psi)→ 30 second delay at same time hitting pressure switch to cut ventilation and kills engines→ then FM-200 agent (30lbs 340 psi)→ then hits 03 dampeners and enters the engine room.

Question 15

Flow of the bilge pump system

Answer 15

Fore peak→ Starboard (frame #15 )

Survivors compartment→ Portside (frame #10)

Auxiliary space→ Port and Starboard (frame #07)

Engine room→ Starboard (frame #02)

Laz→ Aft (frame #0)
