Reply To: Evinrude Fastwin 18 HP 15032 Leaking Around Exhaust

I’m not sure I understand just where the leaks are here….Sounds as if you are saying that water is squirting out around some center screws in the exhaust cover…. Like Dave says, my first thought would be that the screws are bottoming out and not actually tightening the cover. Dave’s washer idea sounds like a good test.
I am very concerned about this issue though. You have just done a great deal of work to this engine, exhaust water leaks that might be getting back into the powerhead could ruin it…
Putting washers under those screws might only just “mask the real issues” here. The washers might stop the external leaks, but internal leaks might still be occurring. I know the thought of pulling that powerhead off and removing those covers again seems like a horror, but you sure don’t want that freshly rebuilt powerhead getting slowly ruined again….
I realize you are not using the original fasteners, I’m assuming your new hardware is threaded all the way up…
