I really don't undertand why the Bravo and TRS drives have a massive lower unit cone to allow exhaust exit under water when most people dont use it.

The increased water resistance?
What about guys that put drive showers on their drives yet flow their exhaust through the drive as well?

That being said, is there a lower unit that bolts to Bravo 1 or TRS that does not have exhaust outlet?

Speedmaster I think?

Where to source them?

Thanks
