1975 Johnson 115hp

Hello. I am new to boating and revelry acquired a 1975 Arrow Glass from a buddy. It needed a water pump and two coils but other then that was supposed to run fine. I bought a brand new battery and when I attempt to start the boat, the starter lifts and engages but it turns very slowly and hesitantly. Also the negative battery cable is getting hot to the touch. Any tips or ideas on how to correct this issue would be greatly appreciated. Tony

Battery cables getting hot when starting boat
by: Bruce

The Armature that spins inside the starter motor is grounding out because of the bearings that it rides on or wore out.
Plain and simple solution, you need a new starter motor. Your battery cable wires are getting hot because you're trying to short-circuit the battery through the starter motor.
Remember that I short-circuit creates smoke and heat depending on how long you are trying to start the boat.
Check your wires make sure they are in good shape with no corrosion remove the power cables from the battery and make sure those connections are good and clean. The battery post can look clean just buy a visual inspection but the problem of a bad connection occurs underneath the battery connection on the post on the battery
