Bigedmustafa....I didn't see your post on the subject, (Nexstar/Magnum 46.) Glad we agree. The Magnum has a chrome liner as opposed to the OS liner. Many guys were switching to the Magnum liner when their OS 46 FX liners were peeling back a while ago. They are interchangeable and half the cost. I'm not bashing OS, I have a bunch of them but I have 3 XLS engines. I just can't pass up a bargain.
