Sea trail on this landing craft with twin Yamaha F300 outboards. Replaced starboard lower unit and both hydraulic steering cylinders and also has a hydraulic tie bar. Wanted to see if the steering held position under load. Works fantastic no issue in the steering, back to steering like it’s brand new. #mobilemechanic #repair #diagnosis #testrun #theoutboarddr #mechanic #outboard #boat #boatlife #fixit #yamahaoutboards #mechaniclife #maintenance #hydraulic | The Outboard Dr.
