Service Marine Lower Units to Prevent Water Damage

Service Marine Lower Units to Prevent Water Damage

Preventing rust and other water-related problems in marine lower units.

Most other Marine Gear Oils fail to make the grade. We learn more on that from our own customers when they make the switch.

_by David Hilgendorf April 24, 2023

Water and gear lube don’t mix. Unfortunately, you can’t avoid submerging your marine motor’s lower unit, and your boat isn’t going anywhere without the lower unit’s combination of gears, bearings and other components that turn horsepower into movement.

Water contamination – you can decrease the effects

Water contamination is bad for several reasons:

Viscosity loss – Viscosity measures a liquid’s resistance to flow or thickness. Your marine motor’s lower unit is designed to use a gear lube of a specific viscosity for optimal wear protection. Water can reduce the gear lube’s viscosity below what the manufacturer recommends, reducing wear protection.

Foam – A film of gear lube forms on the gear teeth it protects. This fluid film absorbs pressure and prevents metal-to-metal contact. Water contamination, however, invites the formation of foam. As the foam bubbles travel between gear teeth, they rupture under the intense pressure leaving nothing behind to prevent metal-to-metal contact, which leads to premature wear and potential gear damage.

Sludge – Water produces sludge, inhibiting heat transfer and increasing the lubricant temperature, which speeds chemical breakdown. The faster the lubricant breaks down, the sooner it fails to provide adequate protection, and the sooner it must be changed.

Rust formation – Water contamination invites rust formation on metal surfaces. Rust can flake off and circulate throughout the gear lube, where it acts like sandpaper and scours bearing and gear surfaces.

 

The solution is AMSOIL’s purpose built Marine Gear Lube

Avoiding contact with water is impossible when boating, so we’ve engineered AMSOIL Synthetic Marine Gear Lube to deliver advanced protection against power loss and gear wear, even with up to 15% water contamination.

WOW!!!

So next time you are about to place your expensive outdoor boat guy sunglasses up on the bill of your ball cap ask yourself if you checked and replaced you lower gear unit’s oil this year!!

Good Day

How Often Should I Change Differential Fluid?

How Often Should I Change Differential Fluid?

Fluid change intervals depend on your vehicle, driving conditions and gear oil quality.

_by David Paiuilldorf | july 26, 2023

A differential is a set of gears that allows a vehicle’s driven wheels to revolve at different speeds when going around corners or over rough terrain. Those gears require lubrication, which is commonly called differential fluid, gear oil, or gear lube.

How often you should change differential fluid depends on your vehicle, driving conditions and fluid quality. If you drive primarily on the highway in temperate conditions and rarely tow or haul, you won’t need to change the differential fluid very often.

However, severe operating conditions break down differential fluid more quickly and place greater stress on the gears and bearings, inviting wear that reduces their lifespan.

Greater load capacity, less lubrication.

Truck manufacturer’s ongoing arms race for the highest towing capacity has resulted in trucks that place more stress on differentials than their predecessors. Meanwhile, differential fluid capacities have largely decreased or remained the same.

For example, compare a 1996 Ford F-250* Crew Cab to the 2021 version. Back in 1996, maximum towing capacity was 10,500 lbs. using a rear differential that held 3.75 quarts of gear oil. The 2021 model offers up to 15,200-lb. towing capacity using a rear differential that holds between 3.3 and 3.5 quarts of fluid.

This means less lubrication is responsible for protecting gears among higher heat and stress. In this environment, inferior lubricants can shear and permanently lose viscosity. Once sheared, the fluid film weakens, ruptures and allows metal-to-metal contact, eventually causing gear and bearing failure. That’s not good!

Increased temperatures in differential

As temperatures rise, lubricants lose viscosity and the extreme pressure between gears can shear the lubricant film, causing increased metal-to-metal contact, friction and heat. Friction and heat create a vicious cycle known as thermal runaway that spirals upward, leading to increased wear and potential gear failure.

Oh and let me tell you a quick story about AMSOIL diff fluid. Under thermal runaway the heat causes the gears or metal to expand just enough to act like a brake. We’ve had RVs comment on reaching 5 to 7 more miles per hour on mountain passes due to the reduction of heat using the AMSOIL Severe Gear. See what I’m saying?

Severe Service Differential Fluid Solution

If you drive via Severe Service towing conditions or haul heavy loads frequently, especially in warmer temperatures, most manufacturers recommend changing the differential fluid more often, sometimes as often as every 30,000 miles. This applies to most work trucks and anyone who pulls a camper, boat or trailer regularly

The best way to determine the recommended mileage interval for differential fluid changes is to check your owner’s manual. Use a high-quality synthetic gear oil to reduce gear wear and maximize your vehicle’s ability to tow and haul.

Amsoil’s Severe Gear Squeeze or Easy-Pack

Amsoil Squeeze Packs cut the differential oil change process in half!

AMSOIL SEVERE GEAR Synthetic Gear Lube is specifically designed for severe service. It maintains viscosity better than other gear lubes under rigorous use and contains advanced anti-wear additives for additional protection.

SEVERE GEAR often costs less than OEM-branded gear oil, and the AMSOIL Easy-Pack or I call Squeeze Pack eliminates the frustrations of changing gear oil. Its flexible design lets you easily reach inconvenient fill holes and squeeze all the gear lube out of the package. Less mess, less waste, less frustration.

And hey, by the way most auto parts stores don’t even carry a known name brand GL5 gear lube these days. Tell your auto parts store to PLEASE carry AMSOIL as it’s about the only real performance player out there and the only one that really works..
