My brother-in-law has a 1992 48 SPL Evinrude on a 20 foot pontoon. He needs a new aluminum prop as he bent his badly. He called the Marina and they told him his 17.5 he has on there is not the right prop but they couldn't tell him which one to get......? Can someone tell me which aluminum prop he needs.... an 11 or 12??? No clue here on how to help him, I figured you could help!!! Thanks.
