I have a 290sp and need to replace the gear case oil. The manual says to use 10W-30 motor oil but that manual is from 30+ years ago. The original outdrive needed replacing so I had a rebuilt one installed earlier this year. Is there any reason to use a different oil?
Also what washers/o rings will I need to replace on the drain and fill holes? Anyone have the part numbers?
And one last question. What lube do I use for the zerk fitting on the bell housing? I was told to lube that periodically too.
The mechanic who replaced my outdrive quit and the shop’s invoice doesn’t list any of this info. Thanks for any help
