E EMF10010 INSTALLATION c C Incorrect engine height or obstructions to smooth water flow (such as the design or condition of the boat or accessories such as transom ladders/depth finder trans- ducers) can create airborne water spray while the boat is cruising.

NOTE: During water testing check the buoyancy of the boat, at rest, with its maximum load. Check that the static water level on the exhaust housing is low enough to pre- vent water entry into the powerhead, when water rises due to waves when the outboard is not running. 3-1
