FX1's are hand laid fiberglass with gelcoat. Superjet's are SMC. Gel doesn't stick to "poop molded compound". Apparently neither does imron paint.

Think the hoods are different from SMC on the SJ's. That where the paint always comes off.

After a grueling day of picking and sanding I was able to remove all of the bonding glue from the bondrail and motor mounts. It was a major pain and it was so hot yesterday! But I got a lot of sanding done and making progress, woohoo.
Today I will be cutting the pump tunnel out. I spoke with @AAlamo about where he cut for his Tom21 conversion. It seems like it is difficult to use the ride plate area for the conversion and most people are keeping the stock FX-1 ride plate mounts. I will make my initial cuts conservatively so I can always open it up larger. Can anyone confirm that you cannot use the SJ ride plate? I would prefer to do that for clearance as it seems like it is a tight fit with the FX-1 ride plate and a larger pump…

Progress being made! One of my buddies did the 144 conversation as well but instead of glassing in a new tunnel, he added reinforcement on the inside and grinded out the tunnel to allow the 144 shoe to work

I've seen SJ ride plates used and even a full wb2 pump cavity and plate. The chines just won't line up. It's definitely a tight fit with the fx1 plate.

I stole this pic from FB. It has to affect the handling but not sure if good or bad. Owner seems happy.

That looks like an awful lot of filling and sanding to make that work

Interesting... I am about to remove the tunnel right now. It will probably make more sense when I am able to mock the 144 tunnel in place rather than just looking at them side by side ha

Also, I still have another FX-1 hull that I am going to repair... That being said, I still have a nice bottom for making a mold if I need to. I was also seriously considering just carefully cutting that broken hull apart and making a mold of the insert holders/ motor mounts and the bottom deck. After reading through Flash's build, I realize there are many possibilities.

i think if the tunnel was cut like storbeck showed in red, the tunnel looks like it might work fine then.

Well, it seems like this 144 tunnel is a bit offset from the 120 tunnel. @hornedogg79 you mentioned that this conversion places the 144 pump about 2” back from where the 120 mounts. So I would be aligning the intake grate mounts, not the pump shoe area? If that is correct, there will not be any room for using the SJ ride plate. The mounting holes are just at the rear of the hull.
This is with the intake grate mounting holes aligned
This is with the pump shoe area aligned
With the 2” setback, aligning the intake grate holes, that should give me the correct driveshaft length for a SJ correct?

I’m also very confused as to how this FX-1 ride plate is going to work with this 144 tunnel…

Look how thick the glass is just in front of the intake grate mount!
144 tunnel needs some trimming…

and now it’s raining… so no more cutting or sanding today.
