The following information describes gearcase draining, inspection and filling procedures for the 2011 Evinrude E-Tec 15, 25 and 30 horsepower engines.
Remove the lubricant level plug (top plug) and then remove the lubricant drain/fill plug (lower plug). Allow the gearcase lubricant to drain into a suitable container. more
Moreover, always check the gearcase lubricant fill level at the upper plug before talking off the lower drain/fill plug. You can use something simple like a tie strap to check the lubricant level. If the gearcase lubricant level is low you should perform a gearcase leak test to pinpoint possible leakage.
Important Note: Different gear oils cannot be combined. If you elect to switch gear oils you should make sure all of the old gear oil is completely drained out before adding the new gear oil. Each gear oil brand formula is unique; mixing two brands will result in a lubricant that is inferior to either of the two that you started with. here
Conversations about lower unit lubrication don't typically generate much interest around the launch ramp. That is until someone gets water in their lower unit and loses a gear case. It happens more than you may realize because all of the power and torque of your engine, turning at thousands of rpms, is concentrated on two small rotating metal surfaces. We’ve seen more than a few boaters spring for a whole new engine because of a blown gear case. Here's what you need to know about outboard lower units and why choosing the right lubricant is so critical.
Most outboard manufacturers recommend changing gear oil annually or every 100 hours (whichever comes first). Some recommend shorter intervals when in salt water. At least one manufacturer, Evinrude, allows up to a 300-hour/3-year drain when using their particular HPF-XR oil. Regardless of the change interval, any accidental introduction of water into the system demands immediate attention. more
Water in an outboard's lower unit often goes undetected until it's too late and expensive repairs are needed. One of the most common causes, particularly among anglers, is discarded monofilament line which gets wrapped around the prop shaft and damages the seals. [links]
Spiral-bevel gears require extreme pressure additives (known in the industry simply as EP additives) to handle the strain of increased shock load and high RPMs. It's important that a lubricant has adequate film strength to prevent the metal-to-metal contact that causes heat and wear. Film strength can be measured using the American Society for Testing Materials (ASTM) D-2782 Timken Load test. The higher the film strength, the less metal to metal contact. Performance lubricant manufacturer Royal Purple has gained a reputation for developing lubricants that possess very high film strength as exhibited in the chart comparing the results of the leading synthetic gear oil and conventional (mineral-oil-based) gear oil with Royal Purple's 'Max-Gear' gear oil. more
There’s a simple answer for that. BRP (Bombardier Recreational Products) doesn’t want you to know the weight or viscosity of their marine gearcase oil. If a consumer is in the dark about the viscosity of the OEM gearcase oil, they will be much more hesitant to buy an aftermarket option. Look for this trend to continue in the powersports industry. Although this ruse is a refreshing departure from the usual threats of warranty denial for using aftermarket oil. BRP is one of the worst culprits for strong-arming customers in this fashion.
It doesn’t appear so. The BRP/Evinrude website refers only to the HPF Pro Gearcase Lubricant containing “synthetic E-P additives”. BRP does not describe the product as being a full or partially synthetic. This would imply to us that the HPF Pro product is a conventional lubricant. AMSOIL Synthetic 75W-90 Marine Gear Lube is a 100% synthetic oil. On this basis alone, we would deem AMSOIL as an upgrade over HPF Pro. [links]
As a bonus, the AMSOIL Marine Gear Lube sells for roughly half the retail price of HPF Pro High Performance Gearcase Lubricant at Evinrude dealers. here
Our answer: Yes we have a direct alternative for Evinrude HPF Gearcase Oil. AMSOIL Synthetic 75W-90 Marine Gear Lube is an ideal substitute for the HPF Marine Gearcase oil sold at BRP/Evinrude/Johnson dealerships. We have verified that the HPF Pro High Performance Gearcase Lubricant is in the 75W-90 range. So there is no issue with going with AMSOIL Marine Gear Lube in Evinrude or Johnson lower units and stern drives.
AMSOIL Marine Gear Lube is ideal for any brand of stern drive, lower unit, V-drive or tunnel thruster requiring the API GL-4 or GL-5 spec. In other words, it is basically universal and can cover most any marine application. It lowers friction, fights wear, prevents foaming and has world class anti-rust/corrosion capabilities. To conclude, this quality AMSOIL synthetic gear oil is a great choice for any marine gearcase. here
Unscrew the dipstick from the oil filler and note the gear oil level. The oil level should be at or near the center of the dipstick, and above the lower mark on the dipstick. [links]
Ensure that the lower unit/out drive/stern drive is fully lowered. As with the outboard lower unit, the oil is best checked when the motor has been running recently, or is allowed to warm to its normal operating temperature.
Place the flushing attachment's discharge ends over the raw water inlets of the motor. Turn on the water full force. Start the engine and allow the motor to warm to its normal operating temperature.
Lower units house the gears, drive shaft, propeller shaft, water pump and raw water inlet for both outboard motors and inboard/outboard motors, where the lower unit is known as a sterndrive, gear case, outdrive or simply a "drive." Lower units use an oil bath for lubrication; that is, the entire unit is filled with oil that requires regular replacement, in most cases, every 100 hours. The gear oil change gives you the chance to inspect the oil for evidence of internal damage.
Shut the motor down. Remove the lower unit's vent plug, a large bore, countersunk screw which you may remove with a standard slotted screwdriver. If oil does not leak from the vent plug when you remove the screw, the lower unit oil level is low. more
