Yamaha's LIT-18616-01-90 is the service manual for the 1998 Exciter 135, which carries the model code EXT1200W.
The book takes in the 1998 and 1999 model years and also documents the Exciter 270, the Exciter Twin and the Exciter. Those boats share hardware, so the factory wrote the common procedures once and separated the specifications by code.
What is inside is the dealer reference for the boat: engine removal and disassembly with measurement points, wear limits and reassembly torque; jet pump service covering impeller clearance and wear ring; steering and reverse gate adjustment; fuel, cooling and exhaust work; bilge, hull and deck hardware; and electrical diagnosis with complete wiring diagrams and test values. On a boat of this age the wiring section usually earns its keep first.
