Thinking more about this, how necessary is a steering lock? I've only trailered this particular boat (tons more experience with sterndrives) a few times (although twice was 500 miles each), but I never used a steering lock device and, if my memory is correct, the engine was still straight up and down at the end of the trip. I assumed that's because of the steering hydraulics and it's really not going to "fall over" to one side or the other.
I just looked through an owner's manual and I didn't find anything relating to using/requiring steering locks - just the aforementioned tilt support.
Also... what does it really matter? I mean, the steering system, I'm sure, expereiences exponentially times more vibration while the boat is underway on the water. Heck, just sitting there in idle (especially a 2-stroke like mine), there's more vibration going on.
Or... why not just flop the engine over to one side and let it rest there?
So, is this something that we do because it makes "us" feel better? Or somewhere along the line some company (that makes a steering lock) convinced us that it's necessary? And then the recommendation (false) gets perpetuated due to the hearsay?
Kinda wondering outloud here...
