I have a nitro hammer the ? is can i swap out the stock engine with a traxxas 2.5. i have been around the rc world for some time but the boats are new to me. thanks for any help

If you wanted to go to the Traxxas motor, get the new one that's coming out.

heck i just put a .18 cvrx by os engine in mineits already faster than my stock and im just getting into the break

will the 2.5 mate up to the stock shaft just thought i would ask before i tear into the stock boat

IF you get new new version, it should be a bolt-in. I wouldn't try to shoehorn the onboard starting system in it though, go with the pull-start version.

thanks i think i will try. i ditched the ez start the first thing i did when i go the engine. when i am done with the nitro hammer it will be a frankinstine boat with spare rc parts from here and there lol

The reason why I mentioned the new version is because of the crankshaft. It has interchangable threads to go from long or short to an SG type. With the old version, it was set up with the SG type for the clutch assembly.

SO does the stock engine that comes in a Nitro hammer a long threaded shaft? Im interested in buying one, and i have a 2.5 and a 2.5r laying around And i know they have alot of power for a little .15. When my Revo was on the stock 2.5R it would wheelie like crazy! And it was very easy to tune and held tune really well. And Tower is selling the water cooling heads for the 2.5s
