The underwater exhaust system (Figure 4.8.1) used
with inboard V-drive engines is designed so that
water from the raw water cooling system enters
the exhaust system through elbows (engine side)
where water and exhaust are mixed. Water and
exhaust are then pumped overboard through muffler
then the exhaust outlet tube and expelled under the
boat. When operating at lower RPMs, there is
insufficient exhaust pressure to utilize the
underwater exhaust system and a conventional
exhaust system with through-hull outlet fitting is
provided as a bypass exhaust system for each
engine. Make sure water is flowing from the exhaust
outlets while the engines are operating. Prior to
every boat use, examine the exhaust system fittings
to ensure tightness.
Hose clamps must be tight at all times to avoid
exhaust leaks.

servicing or winterizing, remove the plug to drain
