Onlyfire GS365 Santa Maria Grill Review: What Can Go Wrong?

The core appeal of this Argentine cooking platform is the santa maria grill height adjustment mechanism, which relies on a top-mounted handwheel, an overhead axle, steel wire rope, and a locking pawl. By raising and lowering the cooking carriage between 2 and 20 inches above the coals, you control heat intensity without adjusting airflow vents. Under normal operation, turning the wheel spools the wire cables evenly over the upper crossbar, while the ratchet lock prevents the loaded cooking grate from dropping unexpectedly. However, this assembly handles significant weight when supporting the three cooking grates, a heavy flat-top griddle, and large cuts of meat simultaneously.

Mechanical cables on any open-fire cooker operate directly above extreme radiant heat. Over extended grilling sessions, grease splatter and heat can dry out steel cables, leading to surface corrosion, wire fraying, or friction binding across the guide pulleys. Unlike open fire ring setups such as the big horn ranch 47 inch outdoor fire pit/grill, which feature static grate levels, this moving system requires ongoing physical inspection. Grill owners should regularly inspect the cable termination clamps and lightly treat the cables with high-temperature food-safe mineral oil to prevent stiffness and binding.

The ratchet lock is another critical mechanical checkpoint. If soot, charcoal ash, or windblown debris accumulates in the gear teeth, the locking arm can fail to seat securely into the ratchet notches. A slipping pawl risks sending a fully loaded grate dropping straight down toward burning coals. Keeping the ratchet assembly clean and clearing away loose ash buildup ensures positive gear engagement every time the grate is adjusted.

Evaluating long-term onlyfire santa maria grill durability requires a realistic look at how painted metal and stainless steel components handle exposure to moisture and high thermal output. The GS365 combines a stainless steel frame and stainless cooking grates with a heavy coated metal firebox structure. Burning split hardwood logs inside the dedicated brasero creates intense localized heat that regularly exceeds typical charcoal temperatures. Over time, these intense thermal cycles will inevitably break down protective paint coatings inside the firebox and along the lower coal pan, leaving bare carbon steel vulnerable to moisture.

Corrosion accelerates rapidly when wood ash is left sitting in an outdoor cooker. Wood ash contains potassium hydroxide, which turns into a corrosive caustic paste when combined with ambient humidity or rain. Implementing a proactive onlyfire grill rust prevention routine is vital for maintaining the structural integrity of the base. Users must use the included shovel and ash poker to clear out spent embers after every cook once the firebox cools down, rather than letting wet ash rest against the metal floor.

Outdoor storage demands diligent shelter. The included waterproof cover provides a first line of defense against rain, snow, and UV damage, similar to maintaining protection on a traeger pro 34 cover durability review standard. Applying an occasional protective wipe of food-grade oil to the interior firebox walls seasons the metal against atmospheric oxidation, particularly during wet off-season months.

The included onlyfire santa maria grill rotisserie kit expands this cooker beyond direct searing by allowing whole poultry, roasts, and loins to slowly rotate over glowing coals. The kit features a dedicated electric motor, spit rod, and balance forks engineered to span the main cooking chamber. Cooking on an open rotisserie differs significantly from rotisserie cooking inside an enclosed grill. Without an insulating lid to trap circulating heat, the food relies entirely on direct radiant energy from the coals below and the adjacent brasero basket.

Unlike thermostatically controlled cookers like the pit boss navigator, heat stability on the GS365 requires active fuel management. The side brasero allows you to burn hardwood down to fresh red embers before pulling them across the floor with the ash poker under your rotating meat. Because the rotisserie motor sits exposed on the outer upright post, careful positioning is required to shield the motor housing and power cord from drifting flames, wind-blown sparks, and direct grease splatter.

Load balancing is essential when operating the spit assembly. An off-balance roast places uneven mechanical strain on the internal motor drive gears as the shaft turns against gravity. Taking the time to center large meat cuts and tightening the prongs firmly prevents binding, motor motor stutter, and premature electrical burnout during extended roasting sessions.

At 286 pounds with an overall width of 68 inches, the GS365 is a substantial backyard installation. The inclusion of a folding side preparation table, tool hooks, and a lower log shelf adds genuine operational convenience, but the unit demands a permanent, level, fire-resistant surface such as concrete, brick pavers, or flagstone. The sheer mass makes rolling the cooker across gravel, grass, or uneven ground impractical. Assembly requires dedicated time, clear floor space, and ideally two people to lift the central firebox assembly onto the cart frame safely.

When considering long-term ownership, finding onlyfire santa maria replacement parts is an important consideration. While standard hardware components such as fasteners, washers, and cotter pins can be sourced from any local hardware store, proprietary parts like the handwheel ratchet arm, axle spools, or specific cable lengths may require direct contact with the manufacturer. Standard wire rope can be measured and replaced if the original cable frays, but preserving original components through routine care minimizes the need to track down replacement parts later.

The included auxiliary accessories, such as the flat-top griddle and secondary grates, provide flexible configuration options. However, lifting and swapping these heavy metal plates while the fire is active can be challenging. Always use the included grate lifter tool and heat-resistant gloves when transitioning from direct grate searing to flat-top griddle cooking over live flames.
