MasterCraft 2009 MariStar X-Series Manuel D’Utilisation

The stereo and components come with a separate manual 

explaining operation of the devices. Please review and become 

familiar with the equipment.

   (MariStar 230, X-30, MariStar 245, X-45, 

MasterCraft utilizes Lenco attitude adjust-

ment plate kits on several models. Dual 

plate kits are available on the MariStar 280, X-80 and 280 STS 

models; a single plate kit is used on the MariStar 245 and X-45, 

as well as the MariStar 230 and X-30. On the dual attitude ad-

justment plate system, the plates operate independently of each 

other to provide optimal performance by redirecting water flow 

near the transom of the boat. These plates have been designed to 

improve the overall attitude of a boat. If used properly, the plates 

will improve the ride, reduce drag, increase speed and improve 

the ride and fuel efficiency of the boat.

The operation of the attitude adjustment plates is basic. The 

plane or planes will be mounted with the actuator(s) on the 

transom of the boat. When the plate(s) is/are lowered, the water 

flow is redirected, creating an upward force at the stern of the 

boat. When the stern rises, the bow will lower.

Since these actuators are electromechanical, they provide an im-

mediate response at the touch of the switch. The switch adjust-

ments are based on the position of the bow. On the dual attitude 

adjustment plate system, the right side of the switch controls the 

starboard plate and the left side of the switch controls the port 

plate. On the single plate system, there is only one switch control.

The system is set up this way to minimize the guesswork while 

underway. To lower the starboard bow, press the right (star-

board) switch where it reads DOWN. To lower the port bow, 

press the left (port) switch where it reads DOWN. On the single 

plate system, press DOWN.

Since our models have different weights, lengths, speed and per-

formance, it will take some practice for the operator to under-

stand how your boat reacts with the attitude adjustment plates 

installed. The plates will allow your boat to get on plane faster 

and continue planing at lower speeds. This will improve visibility 

and the overall safety of your boat. When making adjustments 

of the switch. Continued practice will help you become familiar 

with how the plates perform.

Head Sea:  Lower both plates slightly by pressing BOW DOWN 

on both sides of a dual system, BOW DOWN on a single system. 

This will bring the bow down while maintaining speed. This also 

allows the hull of the boat to absorb the impact of the waves. 

This adjustment will result in a more efficient and smoother ride.

Following Sea:   Make sure the plates are fully retracted by press-

ing BOW UP on both sides of a dual system, and BOW UP on a 

single system. This will bring the plate(s) up to a fully retracted 

position, decreasing lift in the stern and will allow the bow to 

rise. If the plate(s) is/are deployed, the bow may dig.

Windy Chop:   To raise the windward side of the boat on dual 

systems, press BOW UP on that side. If this is not sufficient 

press BOW DOWN on the leeward side of the boat. Do not 

over-trim when attempting this. This will allow the windward 

side of the boat to rise and will minimize spray.

Shallow Water/Hole Shot:   Lower both plates completely on a 

dual system by pressing BOW DOWN on both sides (the single 

plate on a single system). This provides lift in the stern of the 

boat and will keep the bow down. As you throttle up and speed 

increases, raise the tab(s) by pressing BOW UP on both sides of 

a dual system, and BOW UP on the single system.

Uneven Load:  When equipped with a dual system, if one side 

of the boat is higher than the other while running, press BOW 

DOWN on the switch on that side. This will lower the tab on the 

listing side (low side) to bring the boat level.

Porpoising:   To stop porpoising, press BOW DOWN on both 

sides of a dual plate system, BOW DOWN on a single system. 

The plate(s) needs only to be deployed slightly to correct this 

adverse situation.
