I suggest that before you continue with more posts that you read the section for new users, etc.
Posts are very vague and with no information as to what type and/or model of motor.
sounds stupid but how do i start a new post?
Go to the forum that you want to post under. Above the left column that shows the numerous post "Titles", you'll see a blue button "+ Start a new post".
+3 regarding the original question. It's Friday night and I just figured the OP might have been dippin' in the sauce before posting..made no sense to me.
I believe the confusion results from your asking about a sealant for the lower unit to the exhaust housing..of at least that's how I read it. Looks like Adhesive M for the wear plate seal...and just a litttle of that. OMC Gasket Sealing Compound for the threads on the water pump housing screws.Seems like I saw a chart either in the Top Sceret Files or FAQ section listing equivalents for Adhesive M.
