I have lost essentially all power on my 90 hp outboard 1982. Brought it to my local marina to have them check it out and they are telling me cylinders 1,3 and 5 are getting no power and that the top ignition switch is dead. Sounds like it is about a $200 part. Is this something I can tackle myself? Any concern this is just step 1 of many leading to a lot more than my $1,200 investment in the whole boat?
