Exhaust Tube Requirements
IMPORTANT: When installing thru-transom ex-
haust, it is recommended that the exhaust
bellows on the transom assembly be removed.
This is necessary to avoid creating a vacuum at
the exhaust outlet in the propeller at higher boat
speeds. This vacuum could degrade propeller
performance on some boats.
IMPORTANT: When installing thru-propeller ex-
haust:
•
With any application, installation of an ex-
haust tube will increase exhaust noise.
•
With Bravo One and Bravo Two Drives an ex-
haust tube MAY BE INSTALLED for a slight in-
crease in performance.
•
•
With a Silent Choice Exhaust System the ex-
haust bellows must be removed and an ex-
haust tube MUST BE INSTALLED.
With most Bravo Three Drive Models an ex-
haust tube MAY BE INSTALLED for a slight in-
crease in performance. On the following Bra-
vo Three Models, the exhaust bellows must be
removed and an exhaust tube MUST BE
INSTALLED:
