The Variable Trim System provides preset positions for quick settings when adjusting boat trim. When you trim up, you’ll have a drier ride, which helps when towing. When you trim down, you can ride more aggressively while staying glued to the water. Adjustments are instantaneous thanks to the quick activation switch mounted on the handlebar to allow fine tuning of the watercraft trim angle while riding. Simple plug-in connection, and includes switch, cap and hardware necessary for installation. FITS Sea-Doo SPARK with iBR
