Fishop Posted May 24, 2020 Share Posted May 24, 2020 I have a 1994 15hp yammy. Its a 15D model if that helps (dates back to 1982 i believe). I had the leg offand noticed this hole up inside the upper casing (top right corner). Is it meant to be there? It seems very cylindrical. It doesnt show up on any parts diagrams. Also when i fired it up it has exhaust coming up the upper front part or the casing. Seems to be coming from around these grommets. Does anyone think the two may be linked?

kingie chaser Posted May 25, 2020 Share Posted May 25, 2020 (edited) Exhaust port Id say? Looks like a bit of oil coming out of it which is probably the result of the blown head gasket. If you have gases coming out of places its not supposed to then I would be a bit concerned! Edited May 25, 2020 by kingie chaser Link to comment Share on other sites More sharing options...
