While I can find information on the Strelinger marine engines, there is little referring to the outboards.

Below is one news item from 1908 that was included in a larger article covering the First Annual Detroit Motor Boat Show, and one ad from 1914.

Below is Antoine Liberty with the Strelinger.
He went to the Caille company from here and was responsible for the Liberty Drive.

Just for fun, here is another 1908 Strelinger news item.
