EXHAUST INSTALLATION GUIDELINES
The top of the exhaust riser must be a minimum of 12 inches above the water line
with the boat at rest and a full load aboard. It is recommended by the ABYC, and
a Pleasurecraft Engine Group requirement, that there be a drop in the exhaust run
between the engine and exhaust outlet of a minimum of 1 inch per foot of run, with a
minimum of four (4) inches drop overall. The drop must be constant so that no low
spots exist at any point in the exhaust hose. The above are minimum guidelines for
installation, however, meeting the minimum guidelines will not necessarily insure
no water intrusion under all operating conditions. It is the responsibility of the boat
builder to confi rm, for each model, that under any and all running angles and other
conditions of operation, no water ingestion will occur.
