Timing isn't going to make it turn slow.You need to fully charge the batteries and put a meter on the cables and see what the starter is drawing. If you keep cranking without letting it set that will heat up the cables.

A bad starter will cause slow cranking. I replaced the starter on my last boat for slow cranking and the difference was night and day.

Bad starter or really tight motor.
