I haven't used them yet. I bought them from of @ocgrant as he ordered too many. Once I removed my door I was able to clean my existing glides and tracks, and still have the new ones in my stock for future use.
Hey Jeff. I know your slip, and marina well. I don't know which model Sea Ray you're considering, but I would be more concerned with entering/exiting the boat safely from a short pier. We've had times while traveling where we get stuck with a short pier and need to stern in just so we can...
I had mine made in a custom length by Tig Vision, however I believe they have standard lengths as well. The quality is excellent, and exceeded my expectations.
We typically spend 10-14 days at a time on board ours during 4-5 trips per season (not including long weekends every week at the marina or other destinations). We're empty nesters and probably half of the time take our kids and their spouses, or other couples with us. It doesn't seem cramped...
I've been able to source most of my wiper system replacement parts at AM Equipment.
I believe the is the hose you're looking for, and this is the kit for pivot shaft.
They're usually helpful by phone also if needed.
Hope this helps!
