Inspecting the Fuel Pump Sight Tube

tube, see your authorized Mercury MerCruiser dealer to replace the fuel pump.

Drive Belts
!
WARNING
Inspecting the belts with the engine running may cause serious injury or death. Turn off the engine and remove the ignition
key before adjusting tension or inspecting belts.
a - Power steering pump pulley
b - Water circulating pump pulley
c - Crankshaft pulley
d - Alternator pulley
Checking
1. Check the drive belt for excessive wear, fraying, glazed surfaces, or cracks.
NOTE: Minor, transverse cracks (across the belt width) may be acceptable. Longitudinal cracks (in the direction of belt
length) that join transverse cracks are not acceptable.
2. Inspect the drive belt for a proper tension of 6 mm (1/4 in.) deflection. Check the belt tension by applying moderate thumb
pressure on the belt at the longest distance between the two pulleys.
