Kuuma Boat-Grill Mounts
A suitable mount keeps the grill positioned outside the boat’s enclosed living spaces and away from surfaces that could be affected by heat. Confirm the grill bracket, rail or rod-holder dimensions, available clearance, and installation instructions before choosing a mount.
Designed to position a compatible Kuuma grill outside a 7/8-inch to 1-1/4-inch round or square horizontal rail.
An adjustable-height mount designed for compatible 60-degree rod holders equipped with cross pins.
Choosing a Kuuma Boat Grill
Compare Cooking and Storage Space
A larger cooking surface can prepare more food at once, but it also requires additional mounting, operating, and storage space. Measure the intended location and confirm that the lid can open without contacting rails, canvas, seating, or other equipment.
Choose the Mounting Method
Kuuma grills can have folding legs and mounting brackets, but the installation method depends on the individual model. Confirm compatibility before pairing a grill with a rail, rod-holder, or pedestal mount.
Plan the Propane Connection
The featured Kuuma grills use high-pressure propane and may operate from a disposable one-pound canister or a larger refillable tank with the appropriate hose. Canisters, tanks, and connecting hoses are generally sold separately. Follow all fuel-system, leak-testing, ventilation, and storage instructions.
Maintain Safe Clearance
Operate the grill outdoors in a properly ventilated location and maintain the clearances specified by Kuuma. Never use a propane grill inside a cabin or another enclosed area, and do not store hot equipment until it has cooled completely.
Kuuma Marine Water Heaters
Kuuma marine water heaters are available in multiple capacities and electrical configurations. Some models also include an aluminum heat exchanger that can use heat from a compatible engine-coolant loop. Capacity alone does not determine fit: the voltage, mounting arrangement, dimensions, plumbing access, heat-exchanger position, and available electrical service must also match the boat.
A 120-volt, 1,500-watt model with a side-mount arrangement and front aluminum heat exchanger.
An 11-gallon, 120-volt, 1,500-watt heater with a front-rear mounting arrangement and front aluminum heat exchanger.
An 11-gallon, 240-volt, 1,500-watt model with a front-rear mounting arrangement for compatible 240-volt systems.
A larger-capacity, 120-volt, 1,500-watt marine water heater with a vertical four-way mounting arrangement.

Choosing a Kuuma Marine Water Heater
Match the Boat’s Voltage
Verify whether the boat provides 120-volt or 240-volt AC power for the water heater. A heater should not be selected solely because its capacity and dimensions match the available space.
Measure the Installation Compartment
Compare the heater’s width, height, and depth with the available compartment. Leave room for plumbing, electrical connections, heat-exchanger hoses, the temperature-and-pressure relief valve, inspection, and future service.
Confirm the Mounting Arrangement
Kuuma heaters are offered with different mounting-foot orientations. A side-mount model may not directly replace a front-mount or four-way configuration even when the tank capacities are similar.
Verify the Heat-Exchanger Configuration
On models equipped with a heat exchanger, confirm its location and compatibility with the boat’s closed engine-coolant system. Follow the engine and water-heater manufacturers’ plumbing instructions.
Plan for Professional Installation
A marine water heater involves pressurized freshwater plumbing, AC electrical power, and potentially an engine-coolant circuit. Installation should follow the current Kuuma instructions and applicable marine plumbing and electrical standards.

Kuuma FAQs
What is the difference between the Kuuma Stow n’ Go 125 and 160?
The Stow n’ Go 125 has a 125-square-inch cooking surface and a shorter body. The Stow n’ Go 160 provides 160 square inches of cooking space. Compare their dimensions with the available operating and storage areas.
What is different about the upgraded Stow n’ Go 160?
The upgraded Stow n’ Go 160 adds a built-in thermometer and piezo igniter while retaining the 160-square-inch cooking surface and portable mounting configuration.
Can a Kuuma grill be used inside a boat cabin?
No. A propane grill should be operated outdoors in a properly ventilated location with the clearances specified by Kuuma. Never operate it inside a cabin or another enclosed area.
Do Kuuma grills include a propane canister or tank?
No. The featured grills are designed for high-pressure propane, but disposable canisters, refillable tanks, and connecting hoses are sold separately unless a product listing specifically states otherwise.
Will a Kuuma rod-holder mount fit every rod holder?
No. The featured mount has a 60-degree angle and is designed for most compatible rod holders with cross pins. Verify the rod-holder angle, construction, pin arrangement, clearance, and load capacity before installation.
How do I choose the correct Kuuma water-heater capacity?
Consider expected hot-water use, the number of people aboard, recovery needs, available compartment space, weight, and the boat’s electrical capacity. A larger tank requires more installation space and adds more weight when filled.
Can a 240-volt Kuuma water heater replace a 120-volt model?
Not without an appropriate 240-volt electrical system and installation. Match the heater voltage and wiring requirements to the boat’s available AC power.
What does the heat exchanger do in a marine water heater?
A heat exchanger allows a compatible water heater to receive heat from a properly connected closed engine-coolant circuit. The plumbing configuration must follow the engine and water-heater manufacturers’ instructions.
