Water Sport Control - Components & Operation

Overview

The Water Sport Control System integrates Volvo Forward Drive Propulsion, trim tabs, and digital customization for wake shaping and safety when towing riders behind the boat. Water Sport Control is programmed and controlled from the Garmin Displays in the helm and rear cockpit.

Components

Volvo Forward Drive Propulsion
Forward Drive Propulsion’s advanced technology uses two forward-facing, counter-rotating propellers to pull the vessel through the water.

Dual propellers are placed in front of the gear case toward the bow of the boat for performance and safety. The reorganized prop shaft allows a wake surfer to ride right behind the boat without risking injury from the propeller’s blades.

On all sterndrive boats, the Forward Drive can be raised or lowered to further customize the wake.

Trim Tabs

A trim tab is an adjustable control surface attached to the transom of your boat. Actuators, controlled from the digital switching system, raise and lower the tabs. Trim tabs lift your boat by affecting the flow of water around your vessel. When a single trim tab is deployed, the corresponding side of the boat will lift and ride higher in the water. As a result, the boat will roll slightly and the opposite side will sink lower into the water. If both trim tabs are deployed the stern will lift and the bow will dip.

Trim tabs are used to manipulate the water flowing around the boat and to overcome environmental factors that may affect your boat’s performance.

For example, deploying one trim tab will compensate for uneven weight distribution and help the boat run evenly. Deploying both trim tabs will help the boat get on plane when weighed down by passengers. On the 38 Surf, deploying both trim tabs is only possible via “Quick Launch” (see “Quick Launch” below) on the Water Sport Control screen.

The Water Sport Control System uses two trim tabs to shape the wake on each rider’s preferred side of the boat into a clean wave. When the port tab is deployed and the starboard tab is raised, the boat rolls and a wave forms behind the starboard side of the boat. When the starboard tab is deployed and the port tab is raised, a wave forms behind the port side of the boat.

Operation

The Water Sport Control System is controlled from the helm plotters (see, “Garmin Chart Plotters” pg. 39 of your owners manual). The Water Sport Control System can be operated and programmed in any order.

6 - Trailer Mode 7 - Speedometer 8 - Power Trim Assist 9 - Fuel Level

Surf Left and Surf Right

Tap the “Surf Left” or “Surf Right’’ icons to create a wave on the port or starboard side of the boat respectively. You cannot access Surf Left and Surf Right without Water Sport Control engaged. A light on the bow indicates which surf side is active.

Set MPH

Set your speed using the ‘plus’ and ‘minus’ icons on the far right side of the screen. You can manually control the speed using the throttle until you reach the speed set in the system. Once you push the throttle past the set speed, the system will limit the boat to that speed. The Water Sport Control System will maintain speed, as long as Water Sport Control is engaged, until you pull the throttle back toward neutral. The boat will slow once the throttle passes the set speed.

Rider Profile List

Rider Profile Management Menu

Rider Profiles

Once your riders have programmed their preferred surf settings, you can save the settings as a ‘rider profile’ and recall them with one touch. Tap on the “Rider Profile” icon in the upper right hand corner. This will open a drop down list of saved rider profiles. Tap a profile and the system will recall your saved settings and adjust components as necessary.

To edit a profile, tap the “Manage” icon at the bottom of the drop down menu. After tapping manage, select a “User” from the menu on the following page. This will open the Rider Profile page.

From this page, you can customize each rider’s settings. First, tap on a setting in the page’s main menu. Once selected, use the icons on the right side of the page to include a given parameter or not and to change the settings of any parameter. Once your ride is dialed in, tap the “Done” icon to save.

Power Trim Assist

Power Trim Assist, or “PTA,” adjusts the angle of the outdrive to provide the optimal ride. As the boat accelerates, the PTA will raise the outdrive for a smoother ride and better performance. To engage PTA, press the button on the throttle (see, “Throttle” pg. 15 of your owners manual).

Trailering Mode

The “Trailering Mode” prepares your boat for towing on a trailer by retracting trim tabs.

Wake Responsibly

1. STAY AT LEAST 200 FEET AWAY
from the shoreline, docks, or other structures.

2. KEEP MUSIC AT REASONABLE LEVELS
Sound travels well over water. If it’s loud enough to hear at 80 feet back, its likely loud enough for homeowners to hear, too.

3. MINIMIZE REPETITIVE PASSES
Once you’ve run the same portion of shoreline for a while, move on to another area.
