They fit practically all V4 & V6(OX66, HPDI & carbureted) 2.6L, 3.1L & 3.3L outboards.
These are OEM Yamaha bolts and are the standard size used on a very wide range of Yamaha outboard sizes and years. They are NOT cheap aftermarket bolts that are more likely to break in the future (you don't want to have to deal with broken bolts...promise).
Excellent physical condition. Bolts have been tumbled, cleaned & all threads are good.
