i had my boat since 1989 new...this is the first time i replaced the gimbal bearing. it was about welded in there, wow...good thing i always keep my 19 foot bayliner Cuddy in the garage..otherwise i doubt that bearing would of been able to come out after all these years. as i tightened the removal tool there was immense pressure building up and then a loud crack and she broke free...after that loud crack the device began turning easily and soon had the bearing pulled out; to my relief. that loud crack was very alarming to say the least. the installation was effortless in comparison. just make sure you align that grease hole on the right side of the bearing, with the inlet grease tube on the right side of the outdrive housing. tap and pound it in slowly and check for alignment as you go is all. strong sturdy excellently built tool..worth every dime.
