Voltage Regulator Rectifier for Sea-Doo
720 GS, GSI, GTI, GTI LE, GTS, Challenger 1500, Speedster SK & Sportster - 1997-2005 - Part RM30916
This is a brand new improved AC voltage regulator rectifier, supplied as a direct replacement for the original unit fitted to Sea-Doo 720 GS, GSI, GTI, GTI LE and GTS personal watercraft, as well as the Challenger 1500, Speedster SK and Sportster boats, across the 1997 to 2005 model years. It is a plug-and-play, direct fit part that requires no assembly, so it mounts in the original location and connects through the original single three-pin plug.
The regulator measures 41 mm by 41 mm by 21 mm with 105 mm leads, and controls charging to a minimum of 14.5 V plus or minus 0.5 V with a maximum charging current of 20 A or 150 W. It is manufactured with a higher grade of electric components than the original equipment part, so its quality exceeds the OEM equipment it replaces. All products shipped are tested. Marine electrics live a hard life, and a regulator that has been sitting in salt water and vibration is one of the most common causes of a Sea-Doo that will not restart at the end of a day on the water.

Frequently Asked Questions
Does it fit without modification?
Yes. It is a plug-and-play, direct fit replacement with a single three-pin plug on 105 mm leads, matching the original. No assembly and no wiring modification are needed.
What is included?
One AC voltage regulator rectifier with three wires of 105 mm and its fitted three-pin connector. Mounting hardware is not included, as the original screws and bracket are reused.
How do I tell whether my old regulator has failed?
Check the voltage at the battery with the engine running. The system should reach at least 14.5 V plus or minus 0.5 V and the open circuit voltage should stay under 15 V. A craft that cranks slowly after a short run, a battery that will not hold charge overnight, or a reading above 15 V all point to a regulator that is no longer controlling output.
Does the same unit cover the boats as well as the skis?
Yes. The Challenger 1500, Speedster SK and Sportster share this regulator with the 720 GS, GSI, GTI, GTI LE and GTS watercraft. Cross check OEM 278001239 or 278001056 against the number on your original unit before ordering.
