I think that White RE is a replacement motor that someone had already put on it, while the three White CE motors are the originals. So, it has an ID tag, while Tazewell removed the tags from the original CEs.
I'm now running 28.3ci White RE motors on my 425. Note that the 28.3 will NOT fit completely inside the bolt-on 1430 wheelmotor boxes that I'm also using. The body to had to be trimmed enough for them to recess slightly into the tub. They are about flush with the inside wall of the body tub. The back of the wheelmotor boxes are open, so that was not an issue. I had already cut recesses in my tub to run the 21.7ci Char-Lynn S series motors that I tried prior to these REs. I used the original welded on wheelmotor boxes With the Char-Lynns. While the torque of the Char-Lynns was adequate, the taper on their 1" shaft was not the same as the original White 12.5ci RS series, and I could not keep the hubs tight. When I swapped to the "bargain" RE series from
Surplus Center, I bought motors with new 1.5" shaft hubs attached.
Ditto on the taper being critical...
Edit: Just an anecdotal note on torque/power of these 28.3 motors on my 425. This past weekend my youngest son came to visit, towing his 18ft bass boat with his Nissan Frontier V6 4wd. Since I drive an older 2010 Frontier with the same drivetrain, I cautioned him to switch to 4wd before trying to climb my steep gravel driveway. Long story short, for some reason the electronic 4wd failed to engage completely, and he didn't realize it until he was more than halfway up my steep, curving, and sometimes narrow driveway. He only made it to about 20 yards from the top before losing traction. He tried to back down for another try, but the trailer started off into the ditch on a curve. I stopped him, and told him to wait for me to get the PT and a chain. We hooked it on, and I pulled his truck, boat and trailer up the hill and over the crest. The PT was intermittently scratching its 26x12x12 lug tires in the gravel, but the approximate 1400lb tractor pulled not only his midsize pickup, but also a boat/trailer combo that weighs far more than the little PT. I told him to give his Nissan enough gas to help, but not enough to spin, and the rugged little PT did the rest... He couldn't believe that something so small could do it, but it did!
