Anyone happen to know the part # for a 2019 M5 raw water pump? The one I have sounds like it’s about to go out. I have already isolated the issue to the pump and not the valve train which was a major scare to say the least. Yes I could go get one from the dealer, but I am looking to save the drive if possible. I did an online search for the original Sherwood and for a Johnson if available, but came up empty. This is what is on the current Sherwood plate: P1505 / 18247

Thanks for the help. 
 

Malibu sent the wrong rudder.....

that is a great idea and should have mentioned the rudder check.  Often people think it is the steering cable but a lot often do not even lube the rudder housing and things go bad quickly.  @John I.

if the steering is stiff, the cable needs to be replaced.  The direct drive on the response does make this much easier.  Unscrew from the rudder side, unscrew the 4 bolts on the rack and pinion side that is attached to the steering wheel and it will pull out.

The write up by oldjeep is great! 

After disconnecting the steering cable from the rudder, turn the rudder back and forth by hand to ensure it is not binding and the problem is indeed the cable.

Before you spend the money on a cable, please confirm that it is just "stiff" and no pulling to one side when at speed?  If so, that is rudder pre-load and is normal for an inboard slalom ski boat.  

If it is just stiff in general, and more stiff at speed, then disconnect the end of the cable from the rudder tiller and see how stiff it is by moving the steering wheel.  Then check the rudder for smooth rotation...there is a chance your rudder bushing is damaged and is binding and the cable is fine.
