Re: removing lower unit on a Johnson 1999 150 HP
First thing you'll want to do boju is make back up a couple of the bolts in the lower unit to remove the strain on the shift linkage.Hopefully you didn't force it hard and bend something.<br /><br />Anyway,the shift rod coupler is located under the lower carb area in the engine compartment.To release the rod from the coupler,remove the hitch pin from the shift arm as well as the shift cable clevis bolt and push in or to the port side to separate the split coupler from the shift rod.Once separated ,the lower unit should drop.The entire length of the shift rod as well as the driveshaft will all come down with the lower unit.Once removed,insure that you don't turn the shift rod as it will change it's adjusted length.
