The engine compartment should be vented to the outside and also have a blower attached. The smell of diesel oil
and engine exhaust are two different problems, and neither should exist on a boat with modern engine(s). Either there is a diesel fuel
leak or an exhaust leak. Or the engine or engine room is simply very dirty and coated from careless maintenance
and needs a good cleaning
. You should be able to solve this problem (although I guess it's not your problem in this case).
I have a tobago
, which I think is very much like an Athena.
There is no engine blower, as the engine room is vented via a couple of hoses that end behind the moulded aluminium logos.
Do what Mark reccomends, then check out the area around the diesel tank, if it is under the cockpit
When I bought my boat (it was 7 yrs old) I couldn't find the source of the diesel smell. It turned out that behind and under the diesel tank, spills had built up, with dust to a nice layer. The area under the cockpit
seats connects the 2 aft cabins as it is used for the tube connecting the rudders.
Pull out the tank, give the whole area a good clean, then you should be OK,until someone spills diesel again, thats why I always decant using a siphon hose, into a funnel, -its slower but cleaner, and can be done in rough weather
