I just got a checkmate with a 235 hp envinrude. I charged the batt and tried to turn it over. no-go...The starter acuated and the flywheel did not spin. I took the plugs out and tried again, same results. I even put a ratchet on the nut holding the flywheel and it moved barely 1/4 inch. The piston moved about a fraction of an inch when I did that. Any ideas??? <br />Thank you in advance!
