Yamaha SUV conversion project using the FX140 engine on the cheep side for fishing.
I have a 2002 Yamaha SUV 1200 with a new rebuilt engine and was thinking of installing a VX110 engine for better fuel mileage.
I have a 2008 VX Deluxe Jet ski set up for fishing and love the way the engine runs and the fuel consumption, it sips fuel.
I was think of buying another VX110 to pull the engine and everything else needed to support the engine to install in mu SUV.
Has anyone done this? If so any information would be helpful.
would I be able to use the current jet drive and couple the new engine to it?
I have all the tools necessary and know how to do this if it is possible.
I have found this site http://jetskifishing.co.za.dedi30.cp...net/blog/?p=44 that sounds like they have done this and I am trying to contact them also for information on what needs to be done to do the swap.
Anyone with information or ideas will be appreciated on this project.

I picked up a 2002 Yamaha FX140 to use as a donor ski.

I used my 2010 Prius to tow the jet ski home and the trip was 325 miles one way and I got close to 35 MPG. Now that is what I call towing economy.

I did take the ski out to check it out and it runs sweet. Did I tell everyone that I got stopped by the City Police for going to fast. Evidently the Jaguars have a game this weekend and you can only go slow between the Main street and Mathews bridges when they have a home game.

Here is the video of the test ride of the FX140 before the teardown, and the nice Police Officer (LOL) on the river downtown Jacksonville.

donor has been gutted.
I have the engine and pump removed from the donor jet ski. I will do a little cleanup and change out all the hose clamps with SS ones on the 4 stroke engine. Then comes the painful part, Taking my SUV out of service and removing the newly rebuilt 1200 cc 2 stroke engine. I sure hope that everything goes well so the SUV will be back running soon.

SUV has been gutted
I have removed the engine, wiring and pump from the SUV. I have started studying the parts and differences in the two drive trains.

2002 Yamaha SUV pump compaired to2002 Yamaha FX140 pump
I have studied and measured the two pumps and intermediate shafts and have decided what I am going to do to install the 4 stroke Yamaha FX140 engine as for the pump end. There is a 2 inch difference between the two setups both being 2004 year models.
The SUV pump has one impeller housing, this is where the wear ring is located.
The FX140 has two impeller housings, the second impeller housing is like a 2 inch spacer in front of the pump, making the total length of the pump 2 inches longer than the SUV pump. another words the FX140 pump will 2 inches longer from where it mounts to the transom plate than the SUV pump. If you remove the second impeller housing the two pumps look to be the same pumps.
Here is a picture of both pumps. The left is the FX and right is the SUV.
Here is a picture with the second impeller housing removed from the FX140 pump. The left is the FX and right is the SUV.
By using the FX140 pump unit with the second impeller housing you will need to do something about the difference in the length of the cables, trim steering and reverse. The length to the intermediate shaft will be ok.
By using the FX140 pump without the or the second impeller housing or using the SUV pump you will not have any cable length problems but the distance to the intermediate shaft will be 2 inches forward of the original mounting location.
Anyone can speak up if I am thinking wrong

intermediate shaft bearing
I an going to use my SUV pump so that I am not changing any engineering of the jet ski. Yamaha spent a lot of money designing the hull and pump setup and I am not as smart as their team.
I will be making a spacer to space the intermediate shaft mounting point 2 inches forward from its original location. I think that this is the simplest solution.
I will remove the rear bearing housing from the SUV intermediate shaft bearing and install it on the intermediate shaft bearing housing from the FX140. I need to do this because it is what makes the seal to keep water from entering the hull. I will also install a new hose that is 2 inches longer that seals the bearing housing to the hull pipe joint.
Here is the original intermediate shafts. The left is the FX140 and the right is the SUV both 2002 model.
