got the boat out yesterday flushed out antifreez and fog oil. put new plugs in and started on rotor and distributor cap . Took cap off and tried to pull roter off. feels stuck on HELP HELP

it will pry off with flat blade the book has you loctight the new back on but most don't as you don't want any to get down in to dis. shaft. your choice!

If it's Thunderbolt ignition don't worry about it, as it's common for the rotor/shutter wheel to come off rather hard. Being careful not to bend the shaft, pry the rotor/ wheel up and off the shaft with a screwdriver. Don't worry about damaging the shutter wheel as the new rotor comes with a new one.

THANKS just did not want to screw up

Try using two large flat blade screwdrivers, place them 180deg apart and pry with equal pressure, it should pop right off.
