The original-size Marine Kettle 3 A10-207-3 and Cabo A10-703 are both gas grills. Magma also sells a separate charcoal Marine Kettle; it is a different product. We have not tested these models side by side.
Quick Verdict
Consider the round Kettle 3 for its grill-and-stove configuration; consider the Cabo for its rectangular 9 × 18-inch cooking surface.

The Contenders
Category Breakdown
Fuel and model
Winner: DependsBoth models discussed here use propane gas. Magma's separate charcoal kettle is A10-104, not the A10-207-3 Kettle 3.
Cooking layout
Winner: DependsThe Kettle 3 has a 15-inch round kettle format and a stove configuration. The Cabo has a rectangular 9 × 18-inch primary grate; compare how each shape fits your food and storage space.
Materials and mounting
Winner: DependsMagma lists a 304 stainless exterior for the Kettle 3 and 304 stainless construction for the Cabo. Mounts are separate; confirm fit for the grill and boat.
Safe operation
Winner: DependsUse either grill only as directed in its manual, with appropriate ventilation and clearance. Check your boat's fuel setup and marina rules.
Final Verdict
This is a gas-versus-gas choice, not a charcoal-versus-gas comparison. The right format depends on your cooking and mounting needs.
Buying Advice
Look for A10-207-3 for the original-size Kettle 3 and A10-703 for the Cabo; confirm your region's regulator and model suffix.
