Mercruiser Marine Engine – Replacing a 454 with the Newer 496
Miguel,
Thanks for your inquiry and the opportunity at earning your business. The new 502 engine would require all new accessories and is only sold as a complete engine not as a longblock. Therefore the accessories will not be an option to move over. Big block V8 repowers have changed significantly over the past 2 years because of the discontinuation of the 454, 502 and 496 engines from General motors. Mercruiser has developed there own 8.2L engine however it comes standard with the catalyst control system which makes it more costly, and a little more challenging when repowering older appications. The only option with regards to replacing the 385 and 415 Hp big block V8’s is going with a big block 496 CID motor from the Mercruiser CPO product line. The other and more common option for replacing the L29 (330 Hp big block) is the 383 Mag Mpi. I would recommend reading the articles we have regarding repowers and see what option best suits your need. Let me know if you need any further technical information or help placing your order. In either case I will be glad to assist!
P.S. If you are interested in going with a new or remanufactured longblock we do have several options available for these.
