Installing Test Probes

IMPORTANT: The testing dealer or agency will be equipped with the appropriate test equipment and
adapters for this engine. The only item that must be supplied by the boat owner/operator is the exhaust
elbow test probes. These test probes should have been provided with your power package. They should
be carried aboard you boat at all times.

Install exhaust elbow adapter fittings into elbows. Apply Loctite Pipe Sealant with Teflon to threads that go
into elbow. Tighten it securely.
4
Insert exhaust probes into fittings and tighten securely.
The testing agency will connect their adapters and test equipment to the probes to conduct the test. Once the
test is complete, remove the test probes and fittings. Apply Quicksilver Perfect Seal to the threads of both plugs
and reinstall them into elbows. Be sure to save the test probes and fittings, and keep them onboard for future
use.
