Operation Salt Water Operation You can use your Volvo Penta sterndrive in either fresh or salt water. We recommend that you use fresh water to flush out the engine and drive as described in the maintenance section of this manual after you use it in polluted or salt water. This will prolong the service life of the man- ifolds and risers. Trailering Your Boat If your boat will be trailered, tilt the drive unit out of the water. After you remove your boat from the water, low- er the drive unit to the RUN (down) position until the cooling system drains thoroughly. Rinse the entire drive exterior with fresh water, then dry it and spray it with anticorrosion spray.
Before trailering your boat on the road, check the ground clearance of the drive unit. When trailering, the drive unit may be in the up or down position. There must be at least 15 inches (38.1 cm) clearance be- tween the lower gear unit and the ground. If the clear- ance is less than 15 inches (38.1 cm), raise the drive unit. 7743722 - Downloaded from www.volvopenta.com 13/05/2008 20:17:06 22800 NOTE! Be very careful when you back out of drive- ways or cross railroad tracks, so that the sterndrive does not hit the ground. Make sure that the boat fits the trailer properly.
In many cases, loss of performance and speed is due to improper trailer support and too much tie-down pres- sure, which causes the boat bottom to deform. The boat should rest firmly on the trailer with maximum tie- down pressure applied at the bow and transom only. 44 VPA 7743722 English 10-2004
