Trucktok 3310-804622R1 3310-86448A1 Marine Carburetor Replacement for Rochester 2 Barrel Mercarb Carburetor V8 5.0L 305 5.7L 350 Mercruiser Engine with Electric Choke (YELLOW)

💯

Installed carb, was running good on muffs so took her to the water. I have Mercruiser 5.0 1999 Maxum 1900sr. She was running fine until I gave her throttle then she was would run lean. So I took apart carb to find 145 jets when my boat calls for 165. Be mindful of your jet size before installing so you don’t get stuck on the water or damage your pistons

When the original carb was failing after its third rebuild I chose this carb to replace it. I was a bit skeptical as to the quality and if it could be trusted, especially on a offshore boat application. To my surprise the quality was every bit as good as the OEM and at a fraction of the price. My only frustration was the fact there was no documentation as to the size of factory installed jets (it is marketed as universal fit for several sizes of small block Chevy base engines and comes with three sets of additional jets, 135, 155, 165). I even posted the installed jetting question before buying and did not receive any response from the seller, manufacturer or others. Upon receiving the carb and seeing the extra jets I should have deduced that given the gap in range 145s were factory, but rather than guess I opened the carb to confirm. I didnt know what size best to tune this engine since the original carb jets were not readable as to the size so I went ahead and installed the new one with the 145s but found these to be too small and the engine lacked higher RPM performance. I then installed the 155s which worked perfect for my application. Other than this jetting change and some easy electric choke connector changes, the install was simple and the engine runs like a fine watch. I would buy this again and would recommend it to others.

I have not installed this but I can see it is a perfect replacement and should hook right up.I do not foresee any issues but if any arise I will be sure to update. I have used several aftermarket carbs and I have found that it is good to give them a once over before use. look in the passages and make sure they are clear, blow some air through it. This just assures there is no crap floating around in there. I have found doing this can save some headaches. I would buy again. 5 STARS

El mío me salió malo! No pasa gas!
