Includes adapters for Suzuki, Tohatsu, and Yamaha lower units.
This combination unit does both pressure and vacuum testing in 1 unit. Frequent changing of lower unit gear oil is critically important not because the gear oil degrades, its because this is your chance to catch water intrusion into your gearcase. Most people simply drain the oil, check for water, then replace the oil with fresh. However, this tool provides you the opportunity to test the performance of the gear case seals.
The gear case seals on the drive and prop shafts are actually each comprised of two oil seals. One is orientated to keep the oil in the gear case and the other is oriented to keep the water out of the gear case. This tool will allow you to pull and hold both vacuum and pressure, testing for degradation of either seal in the set.
Replaces genuine tool #: 551-34PV.
This tool suits the following: Most Yamaha, Mercury Mariner, Evinrude Johnson, Suzuki, Tohatsu, Chrysler and Force outboards.
