The "lift assist" cylinder on my 1989 88HP Johnson motor does not "assist" at all anymore. I can move it from full up to full down, but this is getting a bit tiresome. <br /><br />From other posts here I'm guessing that I need to change the cylinder. Am I correct?<br /><br />If I decided to put in a power tilt system, would I still have to replace this?<br /><br />Is this cylinder common to other engines? (years/models)If I go to Ebay, is it a good idea to look for a used one? <br /><br />The boat and motor have been in salt water all their lives and the top cylinder connection point looks pretty bad (corroded). How hard is to to replace one of these cylinders? Can I do it while the motor is still on the boat?<br /><br />I know this is alot of questions, but I have been thinking about this for a while now.<br /><br />Thanks!!! mjosiah@summitechnologies.com
