More power and torque require stronger, larger gears to transfer power from the driveshaft to the propeller shaft. Secondly, the leading edge of the gear case disrupts the flow of water over the propeller. Was there a way we could convert this wasted energy into productive power and improve propeller efficiency? A single propeller creates forward thrust, to be sure, but also produces a significant amount of rotational energy as a byproduct. In developing the DF350A, we started with a blank sheet of paper, and considered all these factors in our design and engineering.įirst, we looked at the traditional single propeller design. On top of all this, boat speed is ultimately limited by hull design, the hydrodynamics of the lower unit and propellers, and how the outboards are mounted. However, larger displacement engines typically burn more fuel, adding weight creates a wide range of problems for boats, and more complex mechanical components create reliability concerns. Increasing displacement, or the use of a turbocharger or supercharger, makes more horsepower. Replace the dipstick once you verify that the transmission fluid is at the right level.Making more horsepower is no mystery.If the fluid is particularly low, you might have a leak and should get it checked out. If you need to top it off, be sure to use the recommended transmission fluid.Reinsert the dipstick, then remove the dipstick again to check the fluid level.Wipe off the dipstick with a clean rag, just as you would do when checking the engine oil. Remove the dipstick, being careful not to spill or drip any fluid.Find the transmission dipstick, which is usually brightly colored and toward the back of the engine.Apply the parking brake for safety and make sure the vehicle is in Park.
Obviously, you’ll have to be a lot more careful if the engine is running. Based on the owner’s manual, decide whether to check the transmission fluid with the engine on or off.First and foremost – and this is always good advice – consult your Honda owner’s manual.Many modern cars don’t have a transmission fluid dipstick, so the only person who can check it is a pro.īut if your car does have a dipstick, here are a few things to keep in mind. The first thing to determine is whether you’re able to check the fluid at all. In a practical sense, the most important reason to perform preventive maintenance on your transmission comes down to dollars and cents: getting a transmission fluid flush might cost you a few hundred dollars, but a new transmission will cost thousands. Unlike other fluids, however, transmission fluid doesn’t just lubricate the transmission parts, it also acts as hydraulic fluid, helping keep the transmission cooler and helping with shifts. Stop-and-go driving, towing or other high-stress conditions can shorten its life even further. Like any other fluid such as engine oil, transmission fluid becomes less effective over time. The top reason to change it is to keep your transmission operating at its best. Unless there’s a leak or a problem, some newer transmissions are designed to never need a fluid change.īut let’s say your car does need a transmission fluid flush as part of preventive maintenance. Actually, the first question is “Do I need to change my transmission fluid at all?” For the answer, consult your Honda Owner’s Manual.
