Measuring Exhaust Elbow Height—TowSport

General Information

The height of the exhaust elbows must be within the dimensions specified to prevent water intrusion problems. Exhaust elbow
risers must be installed, if needed, to obtain the proper exhaust elbow height, and exhaust angle. Risers are limited to
152.4 mm (6 in.). Measurement must be taken with the boat in the water. It is important that the boat be loaded as outlined to
simulate the maximum loading conditions likely to be encountered in normal operation.
IMPORTANT: Load distribution recommendations are the responsibility of the boat manufacturer. Any load distribution
conditions that will affect the exhaust system must be clearly communicated to the operator in the owner's manual. For
example, the number of people that can be located on the swim platform simultaneously should be included in the manual, if
this could pose a problem.
Measurements under all loading conditions must be within the following specifications.
