Operation Power Trim and Tilt Operation Trimming and tilting the drive is done from a control switch mounted on the remote control or by using the switches on the dash. When using the dash mounted switches, the bottom button lowers the bow and the top button raises the bow. The switch on the remote control lever raises and lowers the drive when its upper or lower segment is pressed. NOTE! Allow the trim/tilt switch to return to its center position when the drive unit reaches the maximum raised or lowered position. This will prevent your trim/tilt motor from overheating. The trim/tilt motor is protected from overheating by an internal thermal overload switch.
If the electric motor stops while tilting, release the switch and allow the overload switch to cool and automatically reset itself. When the overload switch has reset, tilting may be resumed. Make sure the drive unit is not being restrained, causing the motor to overheat. If the electric motor still does not operate, check the in-line 5-amp fuse in the remote control handle, the 10-amp fuse located on the trim/tilt pump, or the 50-amp circuit breaker on the engine. NOTE! For additional information about Trim and Tilt controls, please refer to the chapter entitled Controls .
Power Trim Operation The power trim is normally used before you accelerate onto plane, after you reach the desired RPM or boat speed, and when there is a change in water or boating conditions. Locate passengers and equipment in the boat so that the weight is balanced fore and aft, and side to side. Trimming will not cancel an unbalanced load. 7743722 - Downloaded from www.volvopenta.com 13/05/2008 20:17:06 To operate the trim, push and hold the switch “bow- up” or “bow-down” until the desired bow position is reached. The trim may be operated at any boat speed or at rest. Avoid operating the trim system when run- ning in reverse.
22766 Observe the trim/tilt gauge, which indicates the bow position achieved. The upper scale (0 to 5) of the trim gauge indicates the “bow-up” positions, and lower scale (6 to 10) of the trim gauge indicates the “bow- down” positions. Determining the Proper Trim The effect of the maximum “bow-up” and “bow-down” positions will be similar for most boats. The bow posi- tion best for your operating conditions could be at any trim setting between the maximum “bow-up” and “bow-down” positions. 22767 The boat will be properly trimmed when the trim angle provides the best boat performance for your operating conditions.
On models without power steering, the trim position that provides a balanced steering load is desirable. To familiarize yourself with the power trim, make test runs at slower speeds and at various trim positions to see the effect of trimming. Note the time it takes for the boat to plane. Watch the tachometer and speedome- ter readings and the ride action of the boat.
