Injecting lower gear oil in lower unit

[Bass2Lip]

I used to have a Merc 225EFI and was able every winter to drain the lower unit and refill with new gear oil with a little pump set up that had a white plastic fitted insert for the lower drain hole and a pump handle to place on top of the gear oil quart. I now have a 250 HPDI and the same white fitting plug does not fit into the lower drain hole on a Yammie - anyone have any suggestions?

Thanks,
Larry from PA

Had the same problem. I took the guts out of an ink, put the hose on one end and put the pointed end in the LU and filled her up.

they make different size fittings, check with a yamaha dealer

you need the metric adapter

Yamaha uses a different size fitting for the lower unit.I got one at my dealer and it works great with the pump.
