Sup guys, I have been postponing the inevitable here. Saw another post talking about this and it reminded me. In the bulletin it says to preferably move the telltale to the top of the block, or to keep the hose running from the exhaust housing, and route the hose above the top of the powerhead and back down.
Here is a pic of my '84. Not sure if this is factory, or if someone re-routed the hose. You guys think I should leave it be, or drill and tap into the top of my precious block :faint2:

Here is the bulletin. http://forums.iboats.com/engine-frequently-asked-questions-faq/johnson-evinrude-adding-tell-tale-222677.html





Thanks guys.

Leave it where it is. They didn't have a prob with that mtr until a few yrs later. If everything is working fine now, leave it.
