EMISSIONS
20-5
As the inboard engine owner, you should be aware that Indmar Products may deny you warranty coverage
if your inboard engine or part has failed due to abuse, neglect, improper maintenance or unapproved
modifications.
You are responsible for presenting your inboard engine to an Indmar Products distribution center as
soon as a problem exists. The warranty repairs will be completed in a reasonable amount of time, not to
exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact the
Indmar Director of Customer Service at 1-901-353-9930.
NOTE: Adjusting engine timing should not be attempted unless you have the proper tools and
equipment. An improperly timed engine can be severely damaged. Do not attempt to start the
engine unless the boat is in the water or an adequate supply of cooling water is applied directly to
the cooling water intake.
Electronic Fuel Injected Engines
NOTE: The MasterCraft LQ9 and 8.1 Liter engines do not have adjustable timing.
1. Start engine.
2. Attach an appropriate inductive pickup timing light to the number one cylinder spark plug wire.
3. Put engine into base timing mode by running a jumper wire from pin “A” to pin “B” on the engine data
link connector. The idle should automatically adjust to 900-1100 RPM.
NOTE: Due to variations in Diagnostic Scan Tools, Indmar prefers using this method of placing the
ECM in base timing mode.
3. Set the timing to 10 degrees BTDC by loosening the distributor hold down bolt and rotating the
distributor until the timing pointer indicates 10 degrees BTDC.
4. Remove the jumper from the data link connector. The Idle RPM should return to normal.
5. Shut the engine down and leave it off for 15 seconds.
6. Repeat steps 1-4 to verify timing.
