When you're sorting through marine steering controls propellers, the practical question usually comes down to one thing: do you need the entire control station or just the cable that moves it? The Kwant Controls 364.G88 -BUK-H Marine Engine Throttle Control Unit w/ Harness and the 6 FT 33C Marine Throttle Control Cable for Boat Engine Inboard Control Lever sit at opposite ends of the same repair. One is a complete throttle control assembly with wiring; the other is the physical link between the lever and the engine.
Quick Verdict
If your boat already has a working control head and simply needs a fresh, smooth-shifting cable, the 6 FT 33C cable is the straightforward choice: it carries a 1-year warranty and is aimed at single and dual station setups. If you need a full throttle control unit and have the ability to test a component properly before relying on it, the Kwant Controls 364.G88 -BUK-H is the more complete part, though its history demands extra caution.

Where Each Product Wins
- The Kwant Controls unit wins when your project calls for a complete control station. It is identified as a Kwant Controls part with manufacturer part number 364.G88, so you have a clear reference for what is included.
- The 6 FT 33C cable wins when you are refreshing an existing cable setup. Its splined core helps the inner core glide with minimal lost motion, which matters on longer or more complex cable runs.
Product Notes
Kwant Controls 364.G88 -BUK-H Marine Engine Throttle Control Unit w/ Harness

At $999.99, this is the all-in-one route if your boat needs the control unit itself, not just the cable. It combines the throttle control unit with a harness, and the part number reference makes it easy to identify. The catch is condition: it is used, and it came from a vessel that was struck by lightning. Components removed in such situations are often replaced as a precaution even when they still work, but the buyer accepts full responsibility for installation, testing, and operation. If you can inspect and confirm it before installation, this is a single-purchase way to get the full control assembly.
6 FT 33C Marine Throttle Control Cable for Boat Engine Inboard Control Lever

At $22.99, this cable is the lower-cost route when the existing control unit works and only the cable needs replacing. It is new, so you avoid the used-part risk tied to the higher-priced assembly, and it comes with a 1-year warranty. The 33C design includes a splined core that cuts down lost motion, and the cable is suited to single and dual stations with stainless steel end fittings and 75mm nominal travel. The limitation is scope: this is only the cable, not the control assembly or harness, so if the lever or unit itself is the problem, this part won't cover it.
Final Choice by Use Case
Choose the Kwant Controls 364.G88 -BUK-H if you are rebuilding a helm and need the full control assembly, and you are comfortable taking responsibility for confirming a part with a lightning-strike history. Choose the 6 FT 33C cable if the existing control head is already working and you are replacing a worn cable; it is lower-priced and a straightforward swap. For routine cable swaps, the 6 FT 33C is the lower-risk buy. For a full control assembly, the Kwant unit covers more ground.
