Yamaha SUV conversion project using the FX140 HO 4 stroke engine for a fishing rig
I have gotten another 2003 Yamaha SVU 1200 that I will be converting to the 2005 Yamaha FX HO 4 stroke engine. I have the donor ski and will do a test run on the FX soon then I will be pulling the necessary parts needed for the SUV. This will be another fun project and will make a great fishing rig when finished.

I have started stripping the Yamaha SUV 1200 to get it ready for the FX 140 HO 4 stroke engine transplant. I ordered new steering and reverse cables for the SUV 1200 and they should be here next week. I also ordered 2 new push-pull trim cables that connect to the twist grip assembly.

Hare is a walk around of the donor ski.

Here is a video of the test run of the FX140 HO. I say that it passed the running test and is now ready to be disassembled and made ready for the transplant.

How fast is the stock FX140 HO and is this what your 2002 SUV has in it? How fast will the 2002 go with the 4 stroke in it?

I am not sure but it looks like the 2005 I have will run 60 to 65 MPH by the display. The video I made is the only time I have run the 2005 FX HO and it was to just confirm that everything was working as it should before taking it apart. I was told that it would run about 65 MPH and it looks to be all stock. It has a completely rebuilt pump on it, a $1,700 bill. The FX140 HO is a 160 hp. rated engine.
In my 2002 SUV I used a 2002 engine setup which is a 140 hp. rated engine and it will easily run 55 MPH but I haven't tried to run it all out yet. Most of my use has been offshore fishing and you cannot run all out unless it is a very calm day and I haven't seen one of the days like that while fishing with the 2002 SUV yet. The 2002 SUV has a R&D ride plate and intake grate installed on it.
Thanks for asking.

The start of a new project is always fun.
Today I was able to remove the steering head from the skis and completely tore both of them apart. I compared the two of them to see if I would be able to use the FX steering head on my SUV. It took me about 7 hours but I made it work like a charm. I had to take the tilt handle from the SUV setup and used it to replace the one in the FX setup. The reason for this is that the FX setup the tilt handle sticks out about 2 inches farther and looks bad. also would interfere with the glove box storage compartment. I had to drill and tap the bottom of the FX setup to be able to use the steering cable clamping or anchoring bracket from the SUV. I also had to modify the bracket so that the tilt function would function properly. I also had to cut out the hole in the fiberglass a little larger on the top and bottom for clearance for the tilt function to work like it should. I used the pitman arm from the SUV on the FX setup. I also had to drill 2 new lower mounting holes to be able to mount the FX steering unit on the SUV. I will need to confirm that the steering cable has enough adjustment to be able to center the handle bars straight, that will come at a later time. The cowling still fits as it should.
This was allot of extra time and work when I could have just used the SUV steering setup but I liked the FX look and feel better plus now I can utilize the electronic sensor in the FX steering setup.
I am now working on mounting the MFD so that I can put the cowling back on.
