After getting boat running again (rotor), I was still experiencing the misfiring and stuttering at higher revs. Replaced distributor cap, no major changes. Turned out Poison and MMandley were right, the plug wires were completely fried. Some even had visible external wear on them from rubbing on engine components over the years. Replaced the wires and she is up an running again with no issues. Just remember to connect plugs in correct order.
But problem solved so thank you all for the help, invaluable this forum is in a country with no authorized dealers
