I guess I would check, take both spark plugs out, grab flywheel & try turning flywheel back and forth & around. If the flywheel turns motor over with still lots of resistance, shoot a little oil into the cylinders to see if that helps, look at prop to see if you are turning lower unit prop around at the same time, or before starting make sure lower unit is in neutral. If still turns over hard I would look for a mouse nest under or near flywheel that is causing the problem. You mentioned you burned out a 40 & a 35hp starter, did the ring gear match the gear off of the 25hp. I think the starter on the 1955 25hp is a 6 volt battery, are those other starters 12 volt. If all checks out the other problem is to check coil lamination for loose bolts or rubbing on flywheel. Gene.
