Seaview PMA167M1 16" Mount Aft Rake Requires Plate

The Seaview PMA167M1 16" Mount Aft Rake is purpose-built for marine electronics installers and recreational boaters who demand precision antenna and sensor positioning on mid-size vessels. This mount assembly addresses a critical need in modern boat setups: achieving optimal signal reception and radar performance when working with aft-mounted systems in confined spaces. Whether you're upgrading your navigation suite or retrofitting electronics on a center console or express cruiser, this rake-style mount delivers the adjustability necessary to clear hardtops, T-tops, and cabin structures while maintaining clear line-of-sight to the horizon.

Built on a robust engineering platform, the Seaview PMA167M1 employs an aft-raked geometry that tilts mounted equipment backward, reducing wind loading and improving aesthetic integration with modern hull lines. The 16-inch span provides substantial lateral support and vibration isolation, critical when mounting heavy transducers, antennas, or multi-sensor arrays on a moving platform. At 11 pounds, this unit strikes a balance between structural rigidity and ease of installation—substantial enough to handle marine-grade loads without requiring reinforced backing structures on most modern composite or aluminum hulls. The mount requires a separate plate (sold separately) for final attachment, allowing you to customize the interface based on your specific transom or hard-mounted installation point.

This Seaview rake mount excels on vessels 25 feet and larger, where aft deck real estate is limited and multiple electronics packages must coexist without interference. Anglers running sonar, GPS, and VHF systems benefit from the adjustable rake angle, which positions antennas clear of cabin obstruction and away from radar shadow zones. Installation requires careful planning of your mounting plate orientation and through-bolting points; professional marine technicians familiar with composite or fiberglass work will find the process straightforward. The stainless steel construction resists saltwater corrosion, ensuring long-term reliability in challenging marine environments.
