Stern Drive Engine: This boat’s exhaust system is an
integral part of the propulsion system.
V-Drive Engine: The exhaust system used on Sea
Ray ® boats with inboard engines is designed so that
water from the raw water cooling system enters the
exhaust system through elbows (engine side) where
water and exhaust is mixed. Water and exhaust is then
pumped through the mufflers then overboard through
the exhaust outlet through-hull fitting. 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.
! WARNING
REFER TO THE ENGINE OWNER’S MANUAL FOR
INSTRUCTIONS AND WARRANTY INFORMATION.
A plug is located on the inboard side of each muffler
(see Fig. 32.1). When servicing or winterizing, remove
the plug to drain the water out of each muffler. Replace
the plug after all water has drained from the muffler.
Refer to Section 2, Bilge and Underwater Gear, Seacocks
and Strainers for information.
