Instead of only looking at the outboard specifications, you should give more attention to the ease of the maintenance cycle. Otherwise, the performance of the outboard will deteriorate over time, and the unit will end up running into issues. So, even though the specifications are important to look at, you should also prioritize the easy maintenance of the outboard. Recent complaints on outboard backfiring thru exhaust have created a ton of complications for anglers. If left unchecked, this issue can be quite problematic for the owners, and here are some things that you can do to fix outboard backfiring thru the exhaust.

Outboard Backfiring Thru Exhaust

1. Check Fuel Flow

Issues with the flow of fuel through the system are the primary reason why your outboard is backfiring thru the exhaust. So, you’ll need to check the fuel level and ensure that there is sufficient fuel mixture in the chamber to optimize system performance. Taking a look at the timing belt can also help you narrow down on this problem with the system.

This issue is often linked to dirty nozzles, and you should clean out the system and try operating the unit to avoid backfiring problems with your outboard system.

2. Check Air Flow

The backfiring problems are almost always related to the quality of the fuel mixture in your setup. A sufficient level of air is required in the system to get the desired performance, and you will need to make sure that the air filters are not blocked. Otherwise, the engine will keep backfiring thru the exhaust, and you won’t get anywhere with the outboard.

3. Replace Spark Plugs

While the spark plugs are not directly related to the backfiring thru exhaust issue, you will still improve the overall backfiring situation by replacing the spark plugs. Luckily, these are not that heavy on the budget and can be replaced rather easily by following a few quick steps. So, test your luck with replacing the spark plugs, and there is a chance that your outboard will be fixed.

4. Fix Leaks

The leaking conditions from the valves and the fuel chamber have also been known to create this problem with the outboard. So, if you’re sure that the airflow is optimal and the fuel supply is not restricted to the chamber, try to isolate the backfiring problem to defective valves. Ideally, changing the valves should fix everything, but it might be a better idea to call an expert to help you with the identification of the leaks.

5. Clean Dirty Carburetor

Lastly, cleaning the dirty carburetor is always a good option when you’re not getting the desired fuel performance from the engine. The best thing you can do here is use some cleaner from the market and run that through the system. However, if you’ve never cleaned the carburetor before then, it would be preferred if you could take the system apart and clean out the individual units. The process might be a bit complex, but it will yield far better results when the outboard is backfiring thru the exhaust.
