Greetings all. I have a 1990 Force 120hp and sometimes when I turn the engine over it cranks like the battery is going dead, even when I have my 50amp engine starter hooked up. The battery is a Marine deep cycle battery, 650 cold cranking amps, it was bought new in February and it's fully charged. Just a few minutes ago I hooked up my meter and the battery was 13.4 volts and when turning over it dropped to 10.6 volts which I know is normal. I disconnected my meter and started to walk back in the house but I turned around and wanted to try it again. Hooked the meter back up to the battery, cranked the engine and it spun fast like it supposed to and the engine started. The starter is Arco P/N 5393. Cylinder compression 1 through 4 is 120-115-115-120 psi respectively and all connections are tight.
Just not sure what is going on here..... I do appreciate your time. Thanks.
Edit: Now after I wrote this post I'm thinking I need to disconnect and clean all of the connections. Lastly, I was reading another post in a different forum and somebody mentioned that a deep cycle battery could cause slow cranking because the plates are thicker than a normal battery. Is this true? Thanks again.
