The Boating Forum - where does yamaha do their engine testing/engineering?

Years ago Mercury based in the northern us, used the florida lake X I think , I assume their techs and engineers and decision makers were in northern US also _ Minnesota?.

-where does Yamaha test and conduct engineering on their outboard motors and more specifically where are their engineers and techs located?.

-Is it a Japan thing? or do they do that type "research" here in the US.

-Do they interact and talk to dealers much, do they have Pet dealers they work with? does anyone on this forum work with them.

- I am curious about "are they ignoring the " "use a 2 micron water fuel seperator filter advice" on this forum,
especially as they only make at present the 10 micron.
it would be easy to also offer a 2, just tell their filter supplier (who is that? wix? someone else?

Yamaha tests on the customers.
Refer to the corrosion and making oil threads.

yes I know

They have a test facility in Alabama on the Tennessee river. Their US offices are in Georgia and I assume most of their engineers are in Japan.

We ran into a similar Yamaha problem except it was with motorcycles. Yamaha North America was no help after many documented complaints. Only through the cooperation of largest Yamaha motorcycle forum, plus the cooperation of their largest race team, added with enough registered complaints, and they finally did something about it.
