Re: does anybody know how too add a telltale pipe into a 1968 18hp evinrude?
In my outboard, the telltale comes off the exhaust housing, not the cylinder block or head. See if you can find a similar model in a year that has a telltale and copy the setup. Also, go to johnson website and search the parts diagrams for a model that has the telltale. You can then order the parts if still available. <br /><br />Here is an example of the parts diagrams available at the Johnson site. <br />

mouseboat, The info in this thread may give you some ideas, it deals with the same thing you're looking to do.<br /><br /> http://forums.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=28;t=037675 <br /><br />According to the diagram for your motor, you have a water passage located at the top of the outer exhaust cover, you may need to pull the outer cover to locate the proper place to drill and tap.<br /><br />The BRP site was working today so you can probably locate the diagram for your motor, if its not try the iShopMarine site.

thanks guys, i see what both of your are saying, it looks easier than i originally thought. but if i doo add a telltale pipe, will the exaust get too hot and damage somthing?
