siwash Posted July 29, 2022 Report Share Posted July 29, 2022 Hey folks, is it possible to clean a lower unit of an outboard and if yes, how? There's build up as you can see from being in the water I assume. Link to comment Share on other sites More sharing options...
Fisherman Posted July 29, 2022 Report Share Posted July 29, 2022 I would try CLR, probably several applications, no scrubbing otherwise the paint may go too. Link to comment Share on other sites More sharing options...
gregtheham Posted August 12, 2022 Report Share Posted August 12, 2022 (edited) I have also used oven cleaner for such “baked on” marine crud...(but test a small area first, for paint reaction)..but ya gotta believe there is an aftermarket marine cleaner designed especially for this.

Can't remember offhand but it will give you the manufacture date and year. I wouldn't buy anything older than 6 months, because we all know that no one in the store would bother to recharge the battery every so often. I would go to a place like Total Battery where they put them into service(add acid) the day they are sold. Link to comment Share on other sites More sharing options...
