The Rheem Commercial Universal Gas Water Heaters are meticulously engineered to seamlessly integrate into compact retrofit environments while boasting the requisite features and capacity to withstand rigorous commercial demands. Appreciation for its compact size and versatile water connections amplifies in tighter retrofit scenarios, streamlining installation processes. It is imperative to note that this model necessitates a 120-Volt power source. Featuring a space-saving design with short heights and narrow jacket diameters alongside top, front, and rear water inlets/outlets for unmatched installation adaptability, it stands out. The system sentinel LED diagnostic system ensures operational integrity through sequential verification via glowing LED lights. Enhanced by a robust tank design, characterized by universal's proprietary steel formulation, patented multi-flue design, and dual coats of porcelain enamel, it excels in heat exchange efficiency. Precision-engineered stainless steel burners with a raised port design, facilitated by a drawer-like assembly for swift inspection and maintenance, underscore its durability. A low-profile automatic flue damper reduces overall product height, complemented by heavy-duty vent hood supports designed for enduring installations. Servicing is expedited by a factory-installed full port, full-flow brass drain valve and hand-hole cleanout for effortless lime/sediment deposit removal. Energy-saving features include a direct spark to pilot ignition system and a gas control system with thermostat adjustability ranging from 100°F to 180°F. Additionally, its built-in corrosion resistance, attributed to a patented anode design with multiple magnesium rods, ensures prolonged tank longevity. Encased in sag and moisture-proof fiberglass insulation around the storage tank and heavy mineral wool insulation surrounding the combustion chamber, it ensures optimal thermal efficiency. For tailored configurations, Rheem's universal line offers water heaters ranging from 35 Gal. to 100 Gal. models, available in a spectrum of BTU/h options in both natural gas and liquid propane variants, ensuring suitability for diverse applications.

The best lower unit gear oil I have used
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
I have been boating my whole life, this is by far the best gear oil. I use this in my Johnson 115 even though this is technically made by Mercury. I seem to get less if any water intrusion into my gearcase with this oil. If there is any, the oil emulsifies the water and continues to protect the gears. I have had better luck with this than Pennzoil marine or others. Highly recommend. It is a blue color and easy to drain and fill.

Does not come with a pump.
Size: 32 oz, Style: 32 Fl Oz, Pattern Name: Lube
The Good: Changing the fluid in the lower unit is a very easy DIY job. This can save you hundreds of dollars each year by doing it yourself. The Bad: You need a special pump to change the oil, and sometimes it comes with the gear lube. Unfortunately this product did not come with it. Luckily my neighbor had an extra one from changing the lube a different boat laying around and was able to use that. The Ugly: If you have to go get the pump, that could cost a few extra dollar but is just an extra nuisance. The pumps are interchangable but you just need to clean it between uses (DON'T MIX DIFFERENT OIL BRANDS)
