1993 Sea-Doo SP / SPI / SPX / XP / GTS / GTX / Explorer PWC Service Manual (P/N 219-100-008)

This Bombardier Shop Manual (219-100-008) covers 1993 Sea-Doo SP, SPI, SPX, XP, GTS, GTX, and Explorer watercraft as manufactured, excluding later dealer modifications.

Supplied as one 305-page PDF in English, organized into 13 sections.

• Engine repair: Rotax 587 and 657 disassembly, top-end and bottom-end inspection, crankcase sealing, and rotary valve service, supported by exploded assembly views.

• Fuel and oil injection: Diaphragm carburetor overhaul, fuel-system leak testing, throttle synchronization, and oil injection pump adjustment, bleeding, and testing.

• Electrical diagnosis: CDI and charging-system tests, magneto service, electric starter overhaul, and model-specific wiring diagrams for tracing circuit faults.

• Jet pump and controls: Impeller removal, drive shaft inspection, engine-to-jet-pump alignment, steering adjustment, reverse-system service, and variable trim system (VTS) repair.

• Cooling and maintenance: Cooling circuit schematics, flushing procedures, water-flooded engine recovery, periodic inspections, and storage preparation for the covered watercraft.

• Hull and body: Fiberglass and gelcoat repair, refinishing procedures, and Explorer inflatable tube leak testing, patching, and valve service.

Written for watercraft mechanics already familiar with Bombardier service procedures, this manual assumes access to appropriate hand tools and the specified special service tools.

Rotax Engine Repair and Specifications

The XP 5852 uses the 657 engine; the other covered models use the 587. Engine chapters detail cylinder and piston inspection, crankshaft checks, bearing replacement, and crankcase assembly, with tolerance charts covering cylinder taper and piston ring end gaps.

Rotary valve timing drawings distinguish the SP, SPI, and GTS settings from those for the SPX, XP, GTX, and Explorer. Component-specific torque tables accompany the assembly procedures, while exhaust manifold inspection and repair are covered with tuned-pipe service.

Carburetors and Oil Injection

The SP, SPI, and GTS use a single carburetor; the SPX, XP, GTX, and Explorer use twin carburetors. The fuel sections distinguish SPX first-production models and the Explorer by their fuel pickup, level-sensing, and carburetor-linkage arrangements.

Those distinctions help match the fuel-system and synchronization procedures to the installed configuration. The manual also warns that XP carburetors have different jetting: fitting the wrong carburetors can damage the engine.

Oil injection coverage extends beyond cable adjustment to pump synchronization, system bleeding, pressure testing, and pump operation testing.

Cooling, Inspections, and Storage

The cooling chapter describes an open, jet-pump-fed total loss system without a thermostat. Its circuit schematics identify hose routing and cooling-water flow through the engine and exhaust components.

Periodic inspection charts separate initial service from recurring checks and include saltwater-use requirements. Storage procedures address internal lubrication, antifreeze protection, corrosion prevention, battery care, and Explorer tube storage.

Ignition, Starting, and Electrical Tests

Separate test procedures address the single generating coil used with the 587 engine and the double generating coil used with the 657. Ignition output checks specify the Bombardier ignition tester, P/N 295-000-008.

Ignition timing views, starting-system troubleshooting charts, and Multi-Purpose Electronic Module (MPEM) test tables support diagnosis. Electrical work requires the manual's precautions against ignition voltage and sparks near fuel vapors.

Jet Pump, Drive Shaft, and Steering

Pump repair includes impeller and wear-ring inspection, bearing and seal replacement, and pressurization testing. Engine alignment procedures specify alignment tool P/N 295-000-089.

The drive shaft installation cautions explain how a folded double-lip seal can lead to seal-carrier bearing failure. Troubleshooting also addresses cavitation, loss of propulsion, and abnormal pump noise.

Steering coverage includes handlebar-to-nozzle alignment. Reverse-gate and cable procedures cover the GTS, GTX, and Explorer, while VTS sections address mechanical service and XP electrical checks.

Hull Repair and Explorer Inflatable Tube

Body repair sections cover fiberglass damage, gelcoat work, and PPG refinishing systems. Explorer procedures extend to tube patches, grab-handle replacement, and lateral bumper bonding; major tube repairs, including rear bumper or cord replacement, are reserved for the factory.

File Format and Readability

The page total already includes three unnumbered front pages—the cover, title, and service-logo page—and 19 blank pages.

Search and navigation: PDF text search is not available, and there are no embedded PDF bookmarks. The printed contents page lists the manual sections.

Wiring diagrams: Small wire-color codes and component labels require zooming. The sideways wiring pages also benefit from rotating the view.
