3303-812648T Carburetor Carb for Mercury Marine 2 stroke 4HP 5HP 3303-812647T1

Saved me a trip to the mechanic. My 15HP Mariner was running rough and stalling at idle, but this carburetor fixed it right up. It bolted on easily and matched the old one perfectly. The engine starts smoothly now and idles consistently without any issues.

Carb went on easy and the bike’s running smooth.

Arrived quickly, ran smoothly out of the box, and the price was better than expected. Second time ordering this, I used the first one on my old machine and it worked great for years.

The new carb made the bike feel like it’s brand new again. No more bogging or hesitation and throttle pickup is super clean. It came pre-set close enough that I only needed minor tuning. Build quality looks better than some of the used carbs selling locally.

Easy to in stall. My 2014 9.9 yummy fired right up and ran smooth like new.
