Engine replacement on a Seadoo Challenger 2001

[benji_165]

I currently have a seized Mercury 240hp EFI V6 engine in my seadoo challenger. Does anyone know of any engine that is the same size as my engine, that I could do an engine replacement with? thanks in advance for any help.

The Sportjet 200 Opti, 210 Carb, or either of the 240EFI's will fit your gearbox. If you are doing a full swap... the 250 will bolt into the hull.

You really can't use the "Outboard" power heads as the splines on the input shaft were different.

I'm currently doing a replacement of my 240 EFI M2 (2002 Challenger). It sounds like you're looking for other options, but I'll throw this out there.

I got the rebuild from here, which came with all the gaskets: Mercury Sport Jet Powerheads

So I recently threw a rod in my 240 EFI, just curious, I found the Mercury Marine 200HP Optimax Sport Jet for sale on Dragon Engine Store, will this be close to a direct drop in to my 2001 challenger? As far as ECU and such. Thanks in advance

Edit : NOT purchasing from Dragon Engine Store, pretty sure they're a scam.
