We have previously written extensively on log strike testing, the variables involved, and more specifically on trying to prevent outboard motors from breaking off and entering boats after striking floating or submerged objects.
This installment focuses purely on durability testing of prototype outboards. It does NOT address the issue of outboard motors breaking off and flipping into boats, the need to make sure production outboards maintain the same durability, production quality control issues, design changes, or other issues. It purely focuses on developing a test stand and a test protocol to test a single prototype outboard motor for durability in striking floating or submerged objects.
Note – the Asian outboard manufacturers tend to refer to log strike testing by the phrase, driftwood testing.
Note – Log strike testing is DANGEROUS, please read the DISCLAIMER at the bottom of this post.
This post is not meant as a “pick one” offering. It is more of buffet from which manufacturers new to log strike testing consider picking some things if they like them and bring some of their own ideas to the table as well to create something that works for them at the stage they are now in.
On Water Log Strike Testing
Most major outboard manufacturers now have a log strike test procedure in place for durability testing of outboard motors. Some still perform on water testing by running flat bottomed boats over floating logs.Read More→
