115HP Johnson cranks hard

[87rocket455]

What would be a few of the symptoms for a 71 Johnson V4 115HP that cranks very hard? It has the CDI box on for the ignition and and a sensor ring on the distributer. It has a brank new marine battery and starter. I didn't get a chance to check compression yet. Also when it does start it runs very well.

Thanks

90% of starter problems are bad connections. remove and clean both ends of the battery cables, so that they are shiney, also the cable from the solenoid to starter. check for nicks in the cables. and make sure the connectors are on the wire good. the cable tend to corrode from the inside out, if nicked, corroded wires, and connections, heat up and cause resistance to the follow of electricity, thus the starter doesn't get enough. you can also take jumper cable pos battery post to large post on starter. with a good connection, the engine should spin. then if the starter is good clean everything and retest. then trouble shoot solenoid. starters can be rebuit at a starter/alternator shop, much cheaper than a new one.

also have the battery load tested at the auto parts store, free, i've had new batteries go bad

Thanks i willl look at all the connections and the condition of the wire, i know the battery terminals are clean and have good contact as well as the starter soleniod and the starter itself, since i had those off recently.
