New Carburetor for Yamaha F20A F25A 20HP 25HP 4-Stroke Outboards Replaces 65W-14901-10 11 12

Plug and play

The listing says "it may fits Mercury Outboard part number: 3329-883314T03. But make sure you can install it." I installed this product on a 1999 Mercury 25 HP Bigfoot 4 stroke outboard and it fit fine. Unfortunately, I was missing the original OEM carburetor, which is shown in the first picture. It has a different linkage than Yamaha, which is shown in the second picture. Without the correct linkage, it would only idle or run full throttle, but it did run fine. You can move the linkage from the old carburetor to this model (or have your mechanic do it). Unfortunately, you can not buy the linkage separately, so I had to buy the Mercury OEM carburetor ($630 with tax/shipping). I was looking at a wait time of several months, but I got lucky and found the one dealer in the whole US with one in stock. I will keep this one as a backup in case the Mercury OEM carburetor has any problems.If I had the original linkage, I could have tested the entire range and given a 5 star rating. My idiot boat mechanic took the old one off for a rebuild, found it was beyond repair and needed to be replaced. He lost interest since it was so long on back-order, and the jerk never returned my old one despite my repeated requests.By the way, if you have never installed a expensive carburetor on a boat in the water with all the bolts and pieces that have to align perfectly in a cramped space and avoided dropping the whole damn thing in the water, then you have not lived life to its fullest. :)

Fuel Connection not at exact same location, but easy adjustment. Works well & a great saving over Yanmar OEM replacement part..

It matched up and fit fine. it will start and idle but bogs out heavily under acceleration. I took it apart and cleaned it just incase there was manufacturing debris or a stuck float. I can not get it to run properly. I have new fuel filter and fresh gas. it is useless to me and a complete waste of time.

Carb body has mold defect. Float sticking open right out of box. Had to disassemble and modify.

Complete carb, carbon copy of the old one. Worked perfectly.
