I've got a 2007 15hp 4 stroke Yamaha. It's been sitting pretty much since it was new. I recently gave the boat its on a make over. Last week I put a new impeller on it. I took it to the lake yesterday and couldn't get it to [censored] out of the indicator. I let it idle for a few minutes and watched what look like all the air purging out of it. There was a lot coming out between the where the lower unit bolts on to the main housing. Then all the air seemed to work itself out. But the indicator isn't peeing. It doesn't appear to run hot. When I first start it the red light comes on for about the first 2 secs then goes off as it should.
So I pulled it back apart this morning and everything looks completely normal. The impeller appears normal and the keeper on the shaft is in place. All appears to be in place and working. But no [censored] out the indicator.
If it ain't yours don't mess with it!
