1995 Sea-Doo Sportster 5892 / Speedster 5891 Jet Boat Shop Manual (P/N 219 100 025)

This 1995 Sea-Doo Shop Manual, Bombardier publication 219 100 025, covers the Sportster 5892 with one Rotax 657 X engine and the Speedster 5891 with twin Rotax 657 X engines. The material is organized into 12 technical sections.

• Engine repair: Engine removal and installation, top-end and bottom-end inspection, PTO flywheel and magneto service, and rotary valve timing.

• Fuel and lubrication: Mikuni carburetor overhaul and synchronization, fuel-system pressure testing, and oil injection pump adjustment, bleeding, and operation checks.

• Electrical troubleshooting: CDI ignition tests, MPEM diagnosis, charging-system checks, starting-system troubleshooting, starter overhaul, and separate wiring diagrams for each model.

• Propulsion and steering: Jet pump rebuilding, drive shaft and seal carrier service, engine-to-pump alignment, reverse gate adjustment, and steering cable replacement.

• Maintenance and cooling: Periodic Inspection Chart, cooling-system flushing, water-flooded engine procedures, and winter storage preparation.

• Hull and body: Gelcoat and fiberglass repair guidance, drain and seat removal, storage-cover adjustments, and painting procedures.

Written primarily for manufacturer-trained jet boat technicians already familiar with Sea-Doo service and maintenance, this manual assumes access to the specified hand tools and special service tools.

Engine Inspection and Fuel-System Service

Engine chapters pair exploded views with cylinder, piston, ring, and crankshaft inspection limits. Top-end and flywheel work can be performed with the engine installed; bottom-end and rotary valve shaft repairs require engine removal.

Carburetor coverage includes diaphragm, needle-valve, and fuel-pump checks. MAG- and PTO-side carburetors receive separate return-orifice specifications. The lubrication section warns that delayed oil injection pump opening from incorrect adjustment can cause serious engine damage.

Electrical Tests and Model-Specific Wiring

Separate Sportster and Speedster schematics are backed by Main Wiring Harness Connections tables, numbered connector references, and wire-color codes. The Speedster's additional green tracer identifies starboard circuits, helping technicians assign tests to the correct engine.

MPEM coverage explains diagnostic beeps, neutral-switch and RPM-limiter faults, and the Speedster's battery-boost circuit. Ignition testing specifies the Bombardier ignition tester (P/N 295 000 008) and resistance checks.

Follow the manual's precautions for fuel vapors, battery isolation, and ignition testing in the engine compartment.

Jet Pump Matching, Alignment and Hull Repair

Speedster port and starboard pumps use different impellers and venturis; the assembly chart identifies the matching combinations. Engine-to-jet-pump alignment drawings specify tool P/N 295 000 089 and shim placement.

Pump overhaul includes wear-ring and shaft-play checks, seal installation, and leak testing. The installation cautions explain how a folded seal-carrier lip can cause bearing failure.

Steering sections cover nozzle alignment and throttle/shifter adjustments. Speedster ride-shoe removal is referred to the service department. The fiberglass section supports damage assessment and repair estimating; it does not replace a complete fiberglass and gelcoat repair manual.

Cooling Circuit and Seasonal Care

The 657 X Engine Cooling System drawing traces the jet-pump water supply through the exhaust and cylinder jackets. This total-loss circuit uses calibrated fittings without a thermostat; seasonal procedures cover drainage and freeze protection.

A Look at Rotary Valve and Carburetor Specifications

These examples are a small selection of the manual's identification and test data for both models.

The rotary valve table specifies P/N 290 924 502 with a 158° cut-out and an actual-size template. Rotary valve cover clearance, measured without the cover O-ring, is 0.25–0.35 mm (.010–.014 in).

Mikuni carburetor testing specifies an inlet release pressure of 110–145 kPa (16–21 psi), with a separate needle-valve leak test of 69 kPa (10 psi) held for 30 seconds.

PDF Navigation and Page Breakdown

Search and wiring detail: Manual text is not searchable. Embedded bookmarks navigate the main sections and wiring annexes. Small wiring labels require zooming, and each model's schematic is split across two PDF pages.

Supplied as one printable, 264-page PDF. The total includes 225 pages of manual content, including the wiring annexes, plus three cover/title pages, four notes pages, two annex dividers, 25 otherwise blank pages, and five additional nontechnical pages.
