whats the difference?
| || |
when the first came out the 425 HP one had forged parts, and the 375 didn't. But Merc changed that. Now they both have cast parts. Only major difference is the cam.
I think they have the same short block, are the heads the same,
I know that they are 40 hp more
385 vs 425, but how is made?
so if you raylar a 496 mag, you get more hp per buck?
they end up the same in the end right?
just looked at the merc marine site,
the new ones are 420 vs 370
and they say wot rpms is only 4200/4600
