I bought a 97 sea ray that had a crack in the block so the dealer installed a reman. The original motor is a LX EFI 5.7l but the reman is a vortec block. The dealer supposedly broke the cam in. I had a chance to take it for a spin today and i took it easy since im breaking it in. A few things i...

I have a 1993 merc 115 and I would like to replace the prop being mine is dinged up pretty good. I took the prop off but I do not see any numbers or anything stamped on the prop. Where did mercury stamp their props? And how can I determine the prop pitch and size without the numbers? Thanks
