Re: [OMC-Boats] OMC Stringer Generation Naming

Drawbacks -- yeah, primarily the boat builders want their life made
easy. They wanted an industry standard mounting system.

OMC dominated the I/O market and Outboard market during the hey day of
electric shifts. Things began to go down hill in my opinion with the
introduction of the Gen-4's.

The more you learn about these units the more you begin to appreciate
their design.

Just repeat after me tell all your Merc Alpha/Bravo friends this:

"No other sterndrive tilts higher, runs quieter, turns tighter, steers
smoother, or shifts easier than a well-running OMC electric-stringer..."

(Actually don't tell anyone -- then there will be more orphans for us
to rescue!)
