Hi,
Am hoping one of you guys out there can help. I have a Honda 9.9 ( early 1980's).I've recently serviced it new plugs, oil, impeller etc, has now got good stream of water out, problem is it runs for up to 30 minutes then overheats and cuts out.I have been told this could be a head gasket or maybe the coils. Can anyone advise please? I would to be able like to be able to sort this problem myself as I am on a tight budget and really enjoy getting out on my boat.
Many thanks, Big Link
