If you got fumes concentrated enough to explode up as far as the
distributor then you got a lot of gas in the bilge. The starter and low
mounted alternators are the critical items. And the likelyhood that the
coasties are going to figure out it had an automotive cap are about nill.
All the plastic will be melted anyway. Coasties probably won't even look
at it if it catches fire unless it's convenient.

OK. It will be a closed cap.

Some Chrysler caps had a vent hole, not all.
Aren't boats with inboard engines supposed to have exhaust blowers to
keep the
engine compartment clear of fumes? Don't these vent well enough so that
a spark
isn't a problem? I ask because I don't know.

Engine compartment blowers should clear the fumes, but if someone
neglects to run it long enough, the spark can exit the hole in the cap.
Insurance may be void.




Repeat after me...........gasoline produces explosive vapors, not
