Default I didn't know Evinrude made a Wankel outboard?

Prototyped it into a racing engine, and was blowing Mercury away.


It's a shame they didn't have the time and finances to really develop
it.

I always heard the weakness was the rotor seals


thjey eventually got great rotor tip seals. *end seals were not a problem.
Emissions were the worst part. *Wankel engineer talked to my engineering
class at San Francisco State and said all the changes for emissions reduced
the power and mileage lots.


I think that R&D could have developed the engine design into being
qite a contender ...eventually. But it would have taken too long for
market etc, and with the newer technology advances, somebody could
probably still do something with it and make it effective.
