Default Engine Comparison... Help?

Hey guys, so i own 2 shockwave 36s, and i was running one of them in salt water.
Long story short- engine is seized and im currently ripping the engine apart and going to redo it.
MEANWHILE im looking at just buying another engine all together.... I HAD the stock .32 Dynamite engine in before.
i was thinking of putting an OS 21VZ-M Turbo.

The old Dynamite engine was a .32 engine
here are the specs...

Product Specifications
Type:2-stroke Marine
Displacement:32 cu in
Bore:19mm
Stroke:18.4mm
Total Weight:350g
RPM Range:28,000
HP:1.18 at 28,000 RPM
Cylinder Type:ABC
Carb Type:Rotary



NOW thats the old stock engine that is stuck or "frozen".... now the new engine that i would like to buy is the OS engine.
Here are the specs...

SPECIFICATIONS
Stock Number: OSMG1627
Displacement: 0.2 cu in (3.46 cc)
Bore: 0.65 in (16.6 mm)
Stroke: 0.63 in (16.0 mm)
Practical rpm: 3,000-40,000
Output: 2.5 hp @ 33,000 rpm
Weight: 12 oz (340 g)
Includes: P7 turbo plug

Now guys, what should i do here??? As some of you probably know, these boats are tricky to handle at top speeds...
this Newer OS engine is about 50 grams lighter, and has about 10k more top end RPM than the stock Dynamite Engine.
So what would give a better engine to this boat?? should i spend the time and fix the old engine...? or should i spend some $$$ and
buy the new OS engine...?
Any idea/thoughts will help me decide guys...
Thanks
Justin
