CAUTION
Damage to outboard will occur if proper water pressure is not
maintained while the boat is under way. Raising the outboard too
high will result in a water pressure drop and overheating of
engine will occur. Proper water pressure must be maintained at
all times during operation of the outboard.
Operation of vessel at some Jackplate positions may lead to loss
of vessel control, leading to possible ejection from the vessel
causing property damage, personal injury and/or death.
