Engine and Hull Preparation

The documentation provides an in-depth summary of competitive preparation for Sea-Doo personal watercraft. Primary chapters detail hull truing procedures, including truing tolerances and proper painting guidelines for Concept and Delta coatings. Coverage extends to structural component sealing, sponson kit installation, and lightweight part integration to optimize stability and hydrodynamic performance during high-speed racing.

Technical content includes engine theory and configuration for Rotax powerplants, focusing on RAVE valve operational theory, rotary valve intake timing, and combustion chamber volume measurements. Detailed porting maps are provided for the 587, 657, 717, 787, and 947 engines to assist with race-level blueprinting. A comprehensive diagnostic flow chart is included for engine leakage testing, covering the cooling system, crankcase, and rotary valve shafts.

Specification Highlights

Cylinder head squish clearance for the 587 engine is documented at 1.30–1.70 mm for production units. The 587 engine uncorrected compression ratio is listed at 11.5:1 in the engine specification tables. Ignition timing correction data for MPEM units is tabulated for precision tuning on 787 and 947 engines. Spark plug gap is specified at 0.5–0.6 mm for all Rotax-powered models. Official Sea-Doo paint codes for hull, engine, and exhaust components are organized for bodywork restoration.
