This may be in the wrong forum....
I have an 88 Sport-Craft C-eagle. 19', 4.3L OMC. And I am noticing fumes, at odd times.
As much information as I can think of.....
The engine was just put in a few months ago, and has about 100 hours on it total. No leaks that I can detect.
I am noticing the "fumes" when I uncover it in the yard, and at random times while sitting at anchor.
General temp here the last few months has been 90+.
I have checked the bilge, and there was no evidence of fuel or oil.
The fumes smell a bit like a rich exhaust mixture. The part that gets me the most, I smell it in the cabin more than anywhere else.
I leave my boat on an angle (bow up) with the plug out, and I have checked the area where it would leak to the ground. Nothing.
I degreased my bilge, threw some chlorox in it for a half hour, scrubbed it clean, and waited. Nothing entered the bilge.
I have also left the plug in it for a few days, thinking something was slowly leaking, and I see nothing in the bilge. Small amounts of water (less than a 1/4 cup) from rain leaking through the hatch in the cabin is all i have found.
I went so far as to taste the water, and there was not fuel/ oil in it.
I ran it on the hose for an hour, at different RPMS (from idle to brief 2500 moments), both with the cowl open and closed. I do not smell anything from the engine compartment, bilge, or even out the exhaust. All seems normal.
I have left the cowl open, hatches up, and let it "breathe" all day. I covered it up last night, and when I went out there to dump the rain water off the cover, I could smell it again.
I can leave uncovered longer, but I live under huge oak trees, and its fall... so I am trying to NOT have to clean mountains of leaves from my boat/ bilge.
I have also taken the access patch off (where the sending unit is) for the fuel tank, and its dry as can be, and doesn't seem to smell.
The only thing I have NOT done yet, is to take the deck blank out over the tank. This is on the list to do this week, but I wanted to see if anyone else had any ideas what could be going on.
The reason I have not taken the blank out yet, is there is nothing in the bilge. Common sense tells me, "if the tank were leaking, it would find its way to the plug". Water flows from the cabin drain and deck drain, passed the tank, and to the main bilge with no issue. This water is also "clean". The other side of me says, "the fuel could be getting soaked up somewhere, but then i would have rot issues".
So I am pretty much at a head scratching moment.
I also noticed the windows of my cabin are getting a "film" on them, though this could be unrelated... The doors are coming out this winter to be replaced as the wood on them has seen better days and there is a small area of rot in the bulkhead to be repaired.
Ideas?
