Best Starter motor ?
 

My starter died this summer, it was a stock 502mpi.
which is the best starter for a 572 ?

Be sure to use "Starter Bolts." They MUST be knurled, otherwise you will have nothing but gear and flywheel issues.

if its a healthy big inch natural then you need to look at jegs or summit for something serious i went thru a few till i found a good one it rocks good ones are 250-400$

MSD starters are total junk and their customer service is a joke as well as liars. just saying !

switched to tilton and never had a problem again. 557cid , 9.5 compression, rolls them over easy.

Are the powermaster good ?

Tilton is a good starter.

Yes. In vehicles anyway. Never tried in marine, ie: never checked if totally sealed or not.

Make sure whatever you get it's marine rated or you could have trouble if you ever have an insurance claim. Does your ignition support start retard? I have a 10.1:1 524 and it starts like a dream with a stock Mercury starter. But I have start retard enabled so no kick back.

I went thru a bunch of starters , mostly in the $300+ range and found this $91 starter to work the best .

Starts my blower motors no problem.
I find the high TQ starters turn slower and take longer to fire off.
