The Search by Model feature allows a user to search by engine brand, model, horsepower, year and/or serial number. Our initial focus for this function includes all Yamaha°, Johnson/Evinrude and Mercury/Mercruiser engine and drive parts that are currently found in our Sierra printed catalog. Unlike a paper catalog, SONAR is not limited to annual updates or the need to condense information to fit a print format Our application team is constantly updating the tool with new applications and information. Model Search for additional OE brands will be released in later updates. Announcements will be made in the coming months as functionality for those brands is included in the tool.
