Mercury Racing Adds Altitude Propeller Line
 

A new option, https://www.speedonthewater.com/merc...ropeller-line/

How do you have through hull exhaust on a outboard boat? For that matter can you open the exhaust on the new outboards?

Quote “outboard-engine-powered boats with thru-hull exhaust.”

And cost of these? Lol

Probably meant thru hub, not thru hull.
mistakes happen.

The new outboards have valves that allow you to open the exhaust a bit.

Maybe a thru-hull outboard exhaust kit is in the works at Mercury Racing and someone spilled the beans. Good spot! :boat:

It's called "sport mode" or sport exhaust on the newer OB's. It just a silent choice type of diverter in the mid section that lets the exhaust exit through a port above the water line. All for noise and zero performance gains. Really only effective at idle for the rumble. Don't hear much difference when running.

Cool though. With my V10 it makes my slip neighbors turn there heads when I fire it up.

Yeah. Like techman said. Controlled through VesselView.

I wonder if the thru hull exhaust will route the exhaust into the boat, or if it will be routed back out again…

whos going to be the first to bolt a set of zoomies on?

I bet that would sound pretty cool,

Older mercury 2 strokes used to have "idle relief" exhaust slots above the waterline to reduce backpressure
