CHAPTER 4 

STEERING CONTROL SYSTEM 

 

 

 

- 18 - 

29z 

 This action over-rides preset automatic trim limits and could drive the top of the 

housing up into the bottom of the swim platform, damaging both.  
 

4.4 FOUR 

TRIM 

MODES 

 

Automatic Power Trim Assistant (PTA) Ranges – 

The trim range is adjusted automatically 

according to RPM. When a preset RPM level is reached, the drive is angled automatically to the 
trim angle specified.  In addition to “idle”, 4 trim angles can be selected at different RPM levels to 
attain optimum comfort/performance. The PTA must be activated for this procedure. One 
example of PTA RPM breakpoint/power trim settings is shown below: 
 
Idle 

  -3 

1500 

 

  -1 

2000 

  0 

3000 

  2 

3500 

  3 

 
The PTA is turned ON or OFF in the EVC Display menu under “Settings/sub-menu PTA”. Port 
side is the “master” for a single engine. 

  The function must be turned “Off” 

before hauling the boat out of the water to prevent any auto trimming if any test are performed 
with the boat on land. 
 

Manual Over-ride.

  When the PTA is activated and the driver desires a drive angle other than 

the presets, use of the Trim Panel buttons momentarily deactivates the PTA until one of the 
preset RPM levels is passed. Automatic mode then resumes. 
 
To determine the best trim angle and ranges, familiarize yourself with the characteristics of the 
boat, recording the RPMs and trim position at various speeds and in various wave conditions. 
 

Beach Range

 – Used for running in shallow water 

 

at reduced speed of not 

greater than 1500 rpm.  Make sure the drive’s raw water intake is never trimmed out of the water. 
 
Lift Range – 

When the drive is tilted to maximum height, but not when running, for trailing. 

Power trim has an automatic stop that cuts power when the preset end limit has been reached. 
The stop is reset automatically when activating down trimming.

  

  Never run the 

engine when the drive is in “Lift Range”. 
 

Auto Kick Up

 – Releases the drive if hits bottom or an object in the water. 

 

This feature only protects the drive when going forward. There’s no protection in reverse.  If the 
function has been tripped and drive released, it must be trimmed back to the original position 
using the control buttons. 
 
Check after any contact that the dirve or propeller are not damaged, or if there are vibrations 
from the drive.  If this is the case, then the boat (if possible) can be run at slow speed to harbor to 
haul and inspect.  Check the oil level in the drive. If colored gray, water has entered.  If this is the 
case or other damage exists, contact an authorized Volvo Penta workshop.  If only the propeller 
is damaged, it must be replaced then the boat run to be sure there is no other damage. 
 

 If the parallel strut shows signs of damage, run at reduced speed to harbor as 

this is a critical steering element and must be replaced.  Never align or weld a damaged strut. 
 

4.5 

BOW-THRUSTER & STERN THRUSTER  

(Optional) 

If fitted, thrusters can be used to greatly increase the maneuverability of the boat at slow speeds 
in tight quarters around docks and slips.
