2007 22Ve MP starter issue

[D_B]

Thanks to this forum, I was able to troubleshoot my no start issue down to a bad distributor cap and rotor causing no spark.
2007 22Ve with MP engine

Problem now is that the starter only goes bang, bang, bang (or pop, pop, pop) when trying to start.

I have good batteries, and good voltage to the solenoid.
I've removed the starter and tested it with the same battery and works perfectly once removed from the engine.
I have checked and reconnected all of the ground wires.

Since it works off the motor, I'm assuming I need to replace the starter and not just the solenoid.
Are there any other places to check?

If I need a new starter, where is the best place to source one? Part number? Top mount, but I assume normal rotation and not opposite rotation.

Thanks for any and all suggestions.

It bangs only once when you turn the key one time or keeps banging?

Are the battery cable leads from the starter to the batter in good condition?

Bangs once then lose power to helm...continues to bang if hold in start position with continuous alarm.
Cables are in good condition.

I do have a 2 battery setup starting on battery 1.
When I try to start in ALL, it will crank, I guess it is a battery problem or could it still be a wiring issue?

If it cranks in "all" then you have a dead/bad battery.
