Lower unit oil change is the same as with your older engine. If the oil is milky in color, then the seal below the water pump and or the seals forward of the prop are bad. As to the gasket or o’ring on the two fasteners, it’s always best practice to replace them. I also always finish the job by using a handheld impact tool to finish tightening those fasteners.
Lastly always remove the prop each year, to lubricant the shaft with waterproof grease and to inspect the area between the prop’s thrust washer and the seal forward of it, for debris like fishing line. |
Thank you! I wish they sold an "oil change kit" for this..

I'm not sure what type of gear oil and oil filter the 2021 BF100A takes. Does anyone know how to find this info for sure?
Boats.net says they need to serial# of my motor to be sure. I don't have that right now. |

| Got the oil filter. But they won't say what gear oil to use, only that it's found in the SHOP manual, or from a Honda shop... Anyone know? |

Do yourself a favor and buy the pump attachment that screws onto the bottle. Most of those will have multiple threaded tips for all manufacturers and the Honda, too.
Found a maintenance kit for 90 HP. I would think it would work for 100 HP. Might want to give them a call to find out for sure. Do you have an owners manual? Found an online Honda owners manual and the specs are same for 90 HP as 100 HP.

The lower case oil is easy. To empty remove the bottom plug then the top (less oil on your hands). Let the oil drain. Using a pump attachment on the gear oil bottle (commonly available, see example in link below) pump the gear oil into the drain hole until it just starts coming out the fill (top hole). Insert the plug in the top hole, then remove the fill hose and insert the drain (lower) plug.
I change the washer each time. The plugs get changed when the slot for removal tool gets too torn up.

Salmon Fisher,
yes, thanks for the reminder! I've used one of those before.
Been out fishing lately? |

Yes, thanks.. It IS easy! Problem I've having is that the owners manual does not give a SPEC for the gear oil. 90W or 75W90? GL-4 or GL-5 (apparently GL-5 is bad for gearboxes with yellow metals in them)... Just not sure what to use! |

Online BF100A owners manual says "API Standard (GL-4) SAE 90 Hypoid gear oil" |

Yes, and my 2006 Honda outboard says GL-4 OR GL5. So it would seem that a 2021 specifying GL-4 would be for a reason.(?) the "internet" says GL-5 can be "corrosive to soft metals such as brass and bronze". There's no brass or bronze in there, but isn't the entire casing made of aluminum (soft metal)!?
Problem is I can't find any GL-4 that is also 90W "marine"... Confusing!
Anyone? |

I work on all makes of outboards as a hobby and have done this for years, I also provide local outboard training. My go to 99% of the time for parts is boats.net easy to work with, they have real people to speak with, they take returns and they can get my my parts quickly if I need them. |
Hi Steve, I'd be curious of your input on my above inquiry about the Gear Oil (see above).. Why is my 2021 BF100A specifying only GL-4, and then the Honda gear oil they sell is GL-4 & GL-5 (Honda part# 08739-90W). The internet is saying GL-4 is a specific type and not just "superceded" by GL-5... |

I find the shop manuals to be hard to follow until I already know the procedure. You can find some good Youtubes that show better how to 1) change oil, 2) replace lower unit lube, and particularly, 3) flush cooling system, and particularly 4) replace the impeller. |

Thanks Robhwa,
Good Point!

A great place. If you catch the pass between McNeil and Anderson at Eagle at low tide, about 50 seals will be on the shoal there. We've had a lot of Biggs orcas here lately, and the seals are very nervous. |
