Assemble the through hull fitting making sure that the arrow points forward. Recheck within 8 to 24 hours. Cabling 0 Route the cable back to the instrument. 0 Avoid running the cable close to flourescent lights, engine, radio transmitting equipment etc. 0 Keep the cable clear of the bilges and secure at regular intervals. 6 7 4.
