Need New Motor For 1998 Malibu Response LX

[SeanGove]

We had our engine block crack this winter from a bad winterize job.  Needing to know what motor to replace it with.  It’s a 1998 response lx. 320 monsoon.  Having a friend do it but need to figure out what specific motor it is. Any help would be appreciated. Thanks

These guys get a lot of mention on this site. With good reviews too.

If you have a place to do the work, swapping over existing parts to a new long block isn't a huge undertaking.  Biggest pain is getting the old one apart and cleaning off old gaskets, mating surfaces, etc.

Of course this could be the time to drop in a killer big mill!

Go for drive by wire so you can run Zero Off!

Do you foot with it? Put in a stroker.

Think it needs one? We pulled our annual Barefoot figure eight tourney every spring up at UW-Stout with our team boats in 02-04, which all had Monsoons. Even the bigger guys had no issue with the speed it could make with two full grown men behind it.

Needs it? No. But more speed/power is nicer. Figure 8 usually only goes 41-43. But at least the response can hold that speed on corners. Unlike Mastercrafts of that era.
