FINAL DRIVE/JET PUMP/BILGE SYSTEM
Pump Drive Shaft Alignment
The drive shaft must be properly aligned to prevent premature wear of driveline components. Always inspect
drive shaft alignment if drive shaft, engine drive coupler, or impeller spline damage is evident. Wear or stripping
of engine couplersplines is usually caused by engine misalignment. Wear or stripping of splines at the impeller
is usually caused by pump-to-hull misalignment. Inspect drive shaft alignment whenever engine has been re
moved or wear is evident on coupler, drive shaft splines, impeller splines, or through-hull fitting/bearing carrier.
Symptoms of drive shaft mis-alignment include:
•Excessive drive line noise or vibration;
•Premature wear of driveshaft, drive coupler, or impeller splines;
•Through-hull fitting or bearing housing failure.
Pump Alignment Inspection Procedure
1. Disconnect lanyard cord lock plate from engine stop switch. Remove battery negative cable.
2. Remove driveshaft/pump assembly. (See pump removal this section).
3. Remove bearing housing from through-hull fitting.
4. Remove tail cone.
5. Remove impeller and stub shaft from pump housing. Inspect bearings for wear or damage and replace if
necessary. See Pump Disassembly/Inspection this section.
6. Assemble pump without stub shaft, impeller, or tail cone.
7. Install stator housing to pump housing. Tighten mounting bolts to 18 ft. lbs. (24.8 Nm).
Stator Housing Mounting Bolt
8. Install alignment tool into pump bearing housing with the smaller diameter coupler end facing toward engine.
9. Slide coupler end of alignment tool into
drive coupler.
10. If engine and pump are properly aligned,
the tool will slide freely into the engine
coupler.
11. If mis-alignment is evident, determine the
probable cause of misalignment from the
following chart and correct the condition.
