16
Engine Submersion
Remove engine from water as quickly as possible and contact your local STEYR MOTORS Marine dealer for service.
It is imperative that your dealer removes all water from the engine and immediately relubricates all internal parts.
Electrical devices must be replaced. Delay in completing these actions may allow extensive engine damage.
Frequently check engine compartment for excessive water accumulation; water depth in bilge should be kept well
below flywheel housing. Engine compartment must enable proper venting to avoid condensation to build up on inner
surfaces.
Bottom Painting
If your boat is in water where marine growth is a problem, the use of an antifouling paint will reduce the growth rate.
* Tin base antifouling paint (TBTA or TBTF) is recommended where its use is permitted.
* Copper base antifouling paint may be used, but will require more frequent inspection and replacement of sacrificial
anodes. DO NOT PAINT any part of the drive unit with copper base antifouling paint.
NOTE: Painting the drive unit with copper base paint will accelerate galvanic corrosion.
* Vinyl-butyl base antifouling paint is a recommended alternative.
*DO NOT USE any graphite base antifouling paint.
NOTE: Never paint anti-corrosion anodes, or their effectiveness will be lost.
See your STEYR MOTORS Marine contract partner for an antifouling paint that is suitable for
your area.
Boat Bottom
The condition of the boat bottom can affect your boat’s performance. Marine growth, present in fresh water as well
as salt water, will reduce boat speed. A boat bottom with evidence of marine growth causes a reduction in top speed
of 20 percent or more. Periodically clean the bottom of your boat following the manufacturer’s recommendations.

17
