Is this a genuine original part?

This is a genuine Raymarine / Airmar manufactured part, designed specifically for Raymarine navigation and fishfinder systems.

How do I know if I need the "Long Stem" version?

The B744VL (Long Stem) provides approximately 2.5 inches (64mm) of additional length compared to the standard B744V. You need this version if you have a cored fiberglass hull, a wood hull, or if you are using a thick high-performance fairing block on a steep deadrise.

Does this include the High-Performance Fairing Block?

No, this SKU is for the transducer unit and mounting hardware only. If a fairing block is required for your installation, it must be purchased separately (Raymarine part number E66023).
