Ayuh,.....

Basically,...
SBCs can have only 1 of 2 different starters,+ which starter is determned by the Block's drillings,+ the flywheel.....

It's Either the Straight Across bolt pattern,...
Or,...
The Staggered bolt pattern....

Whatever 1 you took Off,... Put the Same bolt pattern back on,+ it'll Work.....

hi there ok the one they try to sell to me look the same that my old starter is the Straight Across bolt pattern but like I sai the one was on the boat before is a 9 tooth starter and the new is 11 that will make a diference, Im asking because I work for automotive and for example for cars you cant use the 11 on the 9 tooth or aeither the 9 on the 11.

Maybe new style starter.

Uses less juice to turn.

Just don't forget to put the bracket that holds the front of the starter on.

Or the starter bolts could snap.

If they looked it up, and the #'s match, the bolt pattern match it will work.

Good luck!
