GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
I have a '68 IL4 120hp GMC with OMC i/o. Looking to change the impellar out. Online here there are three different ones listed for that size. How can I tell which outdrive I have and which impellar to order??
