Sea-Doo 18Ah to 30Ah Front Battery Tray Adapter
Upgrade your modern Sea-Doo’s power capacity with this DIY-friendly battery tray adapter. Designed specifically for the ST3 and GTI hulls, this adapter allows you to swap the undersized factory 18Ah battery for a robust 30Ah unit (like the YTX30L or equivalent) without permanent modifications to your watercraft.
The Design Philosophy
Most aftermarket battery kits are over-engineered or overpriced. My goal was to create a solution that is:
- Cost-Effective: Minimal filament usage and utilizes affordable hardware.
- Ultra-Rigid: Engineered to handle the vibrations and impacts of offshore riding.
- DIY Simple: If you can use a screwdriver and a pair of snips, you can install this.
Secure Mounting (No Straps Required)
Instead of relying on factory rubber straps that can stretch or perish over time, this design utilizes two 16" heavy-duty cable ties (zip ties).
- Integrated Channels: The OEM battery tray features specific routing paths that allow you to feed the ties directly through the channels and around the new battery and tray.
- Rock Solid: Once cinched down, the battery becomes an extension of the hull—no sliding, no rattling.
Quality Guarantee & Returns
- Quality is guaranteed. If there is a print error or visible quality issue, we'll replace or refund it.
- Because the products are made to order, we do not accept general returns or sizing-related returns.
