I can understand the confusion. The manual you downloaded is actually correct, even though it’s labeled for the YFM450FAR Kodiak. The reason is that this service manual includes the primary manual for the Kodiak 450, but it also contains supplementary sections for other models, including the 2009 Yamaha Grizzly 450 (YFM45FGY). Yamaha often includes multiple model references in one manual to consolidate information and provide a comprehensive resource for various models and years.
In this case, the YFM450FAR part of the manual serves as the core reference, but the supplementary sections will cover the specifics for your 2009 Grizzly 450. Look for these supplementary sections within the manual to find the information specific to your Grizzly model. The manual is designed this way to provide detailed and organized information for different variations of the 450cc models, so you’ll have everything you need in one place.

Since the battery is good, let’s look at other potential causes.
First, check the starter motor. It might not be engaging due to a faulty solenoid, bad wiring, or a worn-out motor. Are you getting power to the starter motor? Ensure all connections are clean and secure.
Another possibility is that the engine is seized. This could be due to rust or internal mechanical failure, like a broken piston or failed bearing. Try manually turning the engine with a wrench to see if it’s free.
Also, the starter button could be faulty. Worn-out or dirty contacts inside the button can prevent it from sending the start signal. Is the kill switch in the correct position? Lastly, inspect the wiring and fuses for any issues.
Hope this helps, and good luck getting your Scrambler running again!

If your 2005 Mercruiser 496 HO is idling rough, surging, or even stalling occasionally, there could be a few reasons behind it. Since your engine runs on fuel injection, addressing these issues involves a bit of troubleshooting and careful maintenance.
Dealing with Surges:
Surging usually hints at problems with air or fuel delivery. Leaky gaskets around the idle air control (IAC), intake manifold, or throttle body can mess with the air intake, causing the engine to run unevenly. It’s also wise to check the throttle valves for any wear or damage. If they’re worn out, they might not handle air intake properly, leading to surges. And don’t forget to inspect all hoses connected to the IAC or pressure regulator for wear and leaks—they need to maintain the right vacuum pressure.
Addressing Stalling Issues:
Stalling is a bit trickier and needs closer attention. If your engine stalls at idle, start by cleaning the flame arrestor to make sure there’s enough airflow. Testing the IAC is also a good idea to see if it’s opening and closing correctly; a faulty IAC can mess with your idle stability. Also, checking the fuel pressure with a gauge is crucial—it can help pinpoint any fuel system issues. High fuel pressure might flood the engine, so it’s important to inspect and possibly adjust the fuel pressure regulator.
Dealing with Misfires:
Misfires can contribute to rough idling, so it’s important to check your ignition system thoroughly. Take a look at the spark plugs, spark plug wires, and ignition coil for any signs of wear, damage, or malfunction. Replacing any faulty parts can help ensure your engine runs smoothly without misfires.
Taking these steps can help you figure out what’s causing your Mercruiser 496 HO to idle rough, surge, or stall. If you’re not comfortable doing these checks yourself, it might be worth getting help from a qualified marine mechanic—they can diagnose the issue accurately and get your engine running smoothly again.
Hope this advice helps you get to the bottom of your engine troubles. If you need more details or have other questions, feel free to ask!

Understanding the Oil Pressure Sensor
The oil pressure sensor is a crucial component that monitors the oil pressure within your engine. It sends this information to the Powertrain Control Module (PCM) using three circuits:
.
This sensor works similarly to the Manifold Absolute Pressure (MAP) sensor. Different oil pressures generate different output voltages, which the PCM then uses to relay information to your dashboard. This helps operate the oil pressure gauge and activates the check gauges lamp if needed.
Removing the Oil Pressure Sensor
Start by disconnecting the negative cable from your battery to prevent any electrical issues.
