I am a first time user and pleased to be a part of these forums. It's great that these are made available to help us "do it yourself".
Hopefully this question will make sense:
I had my boat winterized, and when I picked it up the mechanic told me "don't forget to re-install the drain plug (in a baggie) that is taped to the steering wheel... it goes on the bottom of the exhaust manifold"
So a year later I get the boat out of storage and go to work. Well, I found two threaded holes on the bottom of the manifold, and the 1/4" brass plug fit nicely in the stern end of the manifold. I got concerned about the threaded hole in the middle of the manifold, so I called the people who winterized it and unfortunately for me they have gone out of business. I called other dealers in town and they had no idea, other than to drag the boat in and they would look at it.
I tried an 1/8" plug and it was too big... I tried a 1/16" plug and it was too small. My guess is it might be a bolt thread, but I don't have a bolt that will fit.
I dug around the internet trying to find out what this hole might be and today I found a drawing (parts breakdown) that shows a good pic of the manifold. It shows both holes, and it shows a 1/4" plug that belongs at the rear hole. It does not show anything that indicates a plug or bolt belongs in the center hole. Here is a link to the print I found:
Exhaust - category details
My question is can someone who may have worked on one of these give me a verification as to whether this middle hole is something that is not plugged and maybe it is used to mount an accessory?
Thanks in advance...
