I have a 1977 7.5 hp Wards k751 outboard made by Clinton. There are no drain and fill holes to put in 90 wt oil in the lower unit as I've seen in other outboards. Can anyone advise me on how to lubricate the lower unit. Thanks
<br /><br />Remove the prop, then remove the bottom gearcase cap. You'll probably find a thin white grease in there. That's what you'll need to put back in. I have two old tubes of LubriPlate 105 Marine Grease. I hope you can still get it. One tube will last you a lifetime. I tried putting gearlube in mine, but it leaked. The seals aren't terrible impressive on these.
