swapping a 650 into a js300

[Brian_216]

I have a JS 300 and just for fun -and to have a backup ski Im debating swapping in a 650 from an x2. What will I need to make it happen that wont be on either ski? Both are perfectly running skis, the x2 is my friends and hes been trying to sell it, If this swap happens there will be a nice x2 hull for sale :silly: and we may have a monster of a backup ski. :Banane01:

aside from all that can someone clear some things up- Im told the hull on the js300 is the same as the 440/550 and it uses the 440 pump which is supposedly stronger than the 550 pump? (also open to suggestions for a prop with this swap) And is it worth taking 3 out of the back of the hull to make it a backflip monster?

All you need are the 550 engine mounts,a 550 bed plate and an adapter plate that mounts a 650 engine to the 550 plate ,however my understanding is you are better off with a 550 pump setup as it is a lower rpm pump and produces higher thrust numbers,pump loading on a 440 pump is an issue with a 650 engine.

is there any way to re-drill one of the plates to make it work?

Adapter Plate

Where can I buy the adapter plate I need to make this type of swap?

Ebay I believe JRE is the mfg of those plates.
