Measure Transom Angle Introduction

Seakeeper Ride Controllers must be mounted as close to flush and parallel with the running surface of the hull as possible, as explained in Section 5. This portion of the installation requires installer to measure the transom angle at the chosen Controller locations.  

The Ride 750 Series controllers allow for some adjustment in seal plate angle after installation to fine tune the equipment. We strongly recommend attempting to install the equipment as precisely as possible to achieve a flush and parallel Seal Plate. If the Seal Plate angle needs to be adjusted after adhesive cure it can be done.  

The Wedge Pack Assembly (Items 4, 5, 6, 7, and 8 in Inventory Parts) allows for the adjustment of the Controllers to the boat’s transom angle. The figure below illustrates the differences in the angle between the aft end of the running surface and the transom (A) and the resulting effects on Wedge Pack selection (B). The top two images show correct angle adjustments. The bottom two images show incorrect angle adjustments. 

For optimal performance, the Seal Plate must be completely flush with the aft end of the running surface of the boat, which will eliminate angle C in the figure above. The Seal Plate can angle upward up to 2 degrees with a negligible effect on system performance. DO NOT mount the Controller angled upward more than 2 degrees. DO NOT mount the Controller angled downward at all.
