7.5.1 Engine exhausts

The engine exhausts are underwater and placed at the sides of the aft platform. This system reduces the smoke that usually tends to soil the yacht’s stern.

Exhausts must be maintained and checked at regular intervals to avoid the formation of build-ups that could prevent the correct gas ejection.

WARNING

When starting the engines, check that water comes out of the exhaust; this means that the engines cooling system works correctly and that the exhaust is cooled. Accelerate if no water comes out.
If the problem continues, contact the RIVA After Sales & Service department.

CAUTION

A strong smell and a light smoke from exhaust insulation are normal during the first period of use.

WARNING

Avoid prolonged use of engines at low speeds to avoid overheating of exhaust pipes due to reduced cooling water circulation.
