Model-Specific 4-TEC Coverage

This BRP shop manual applies to the listed 2006 Sea-Doo model and model-number combinations. It separates the different Rotax 1503 installations instead of treating every 4-TEC model as the same configuration.

GTI and GTI SE coverage includes the naturally aspirated 130 HP engine. GTX and GTX WAKE use the naturally aspirated 155 HP configuration. GTX Supercharged is covered with its non-intercooled supercharged system, while GTX Limited, RXP, and RXT coverage includes the intercooled supercharged configuration.

Those differences are reflected throughout the intake, exhaust, fuel, cooling, supercharger, engine-management, and technical-specification sections.

Engine, Diagnostic, and Electrical Content

Engine coverage includes removal and installation, engine-to-PTO alignment, engine leak testing, air-intake and intake-manifold service, intercooler work, supercharger inspection and overhaul, exhaust service, PTO housing and magneto repair, lubrication, closed-loop cooling, cylinder-head service, timing components, valve train, pistons, connecting rods, crankshaft, balancer shaft, and cylinder-block work.

The engine-management section covers EMS operating principles, fault-code troubleshooting, B.U.D.S. communication through MPI and MPI-2, ECM/MPEM procedures, injectors, throttle body, throttle-position sensing, idle control, crankshaft and camshaft position sensors, pressure and temperature sensors, knock sensing, oil-pressure monitoring, and TOPS-related diagnosis.

Fuel and electrical chapters include fuel-system leak and pump-pressure testing, ignition, charging, starting, DESS key programming, gauges, sensors, fuses, battery and starter-cable terminals, wire-color codes, and connector service for Deutsch, Packard, AMP, and ECM connectors.

Propulsion, Steering, and Special Procedures

Propulsion coverage includes jet-pump inspection and disassembly, impeller and wear-ring service, impeller-shaft bearings, drive-shaft and carbon-ring components, reverse-system service, Variable Trim System testing, steering alignment, and O.P.A.S. inspection and repair. Hull and body sections address adjustment procedures and fiberglass or gelcoat repair.

Special procedures cover towing a watercraft in the water, submerged-watercraft handling, water-flooded engine recovery, contaminated-oil removal, and the oil boil-out procedure.

BRP service tools are identified where required, including the engine alignment shaft, engine alignment adapter, camshaft locking tool, supercharger gear holder, supercharger support plate, and leak-test pump. Reference material includes the Engine Management System Diagram, Fuel Pump Diagnostic Flow Chart, Ignition System Wiring Diagram, closed-loop cooling-system views, exploded component illustrations, model-specific specification tables, and the main wiring diagram.

Compatibility and safety: This description summarizes the manual’s coverage; it does not replace the manual’s procedures, warnings, test conditions, torque specifications, or required service tools. Fuel, electrical, cooling, supercharger, and propulsion work can involve pressure, heat, rotating components, and high electrical current. Follow the model-specific procedures and safety notices in the manual before performing service.
