My 454 has the early style sea pump that is the 3 piece design...my question is, can I replace this with the 2 piece design found on the late model pumps? I cracked the section that the hoses conect too and cant locate a replacement that comes with that?

Any help would be great!

Yes, done it. 3 piece is considered superior however. More leaks but better wear.

Here's possibly the best answer to both wear and performance. The reason three piece has always worked great is dual wear plates or a wear plate on each end of the impeller. The plastic body wears day one.. We offer the feature in a two piece design. http://www.hardin-marine.com/p-14544...rhaul-kit.aspx

Looks very nice. Looks like you need to buy barbed fittings as well.

I put this stainless pump on my boat and I am very pleased with it. I think it is well worth the money for what that's worth.

I purchased this housing and I seem to be running a little hotter than with the plastic housing, but I don't have to worry about replacing the housing every season. I have started removing the impeller at the end of the season so I can get a couple of seasons out of it also.
