Why won't my Sea-doo Boat engine start?
- LlatoyascottAug 1, 2025
If your Sea-doo Boat engine won't start, several factors could be the cause. It could be due to a discharged battery or bad connections, so check the battery's charge and the battery posts. Other potential causes include a burnt 20 A fuse (check the fuse), no power at the VCM (check for battery voltage on VCM wire connector pin 6-G), a bad ground (check for continuity with ground on VCM wire connector pin 6-D), no power at MPEM (check voltage on MPEM wire connector pin 3-26), a defective DESS post (check DESS post), or a defective VCM (replace it).
