I recently purchased a 140 Evinrude from a friend and was wondering if anyone can help me figure out what year it is and if it's a looper or crossflow.
Model # E140TXCUA
Serial # G1446324

Thanks for any help!

87 25"

most likely its a looper b/c in 87 they were rating the motors at the prop and 140 prop would be a looper but im not positive

[CSD23]

Thanks for the help! That was fast. I believe it's a looper also because it looks skinnier than a crossflow, right?

[Scream And Fly]

If it's an '87, it's certainly a looper :)

Hope it will make my viper scare me when i'm done with it!

[hsbob]

scarey maybe not but it'll a good motor with fair preformance.

I've been told that the looper will produce higher rpms than the crossflow, is this true and what kind of rpms can i expect with out blowing it up right away?

Don't try using a 25" motor on a Viper. That is an accident waiting to happen. Too high of a C of G.

HI. Ithink 6000 rpm is good thing to keep in mind,if you want dependable power. Either engine can turn more , whats important is to have the engine turning the prop not the prop allowing the engine to turn higher.[advantage looper more power band torque]. Agood weight carrying prop 24 raker lighter weight 26 to28 hipo style prop set-up is so important and fun thanks.

I didn't plan on using the motor as a 25" shaft, actually when I went to get it I thought that I was getting a 20" shaft but my uncle said we can change that motor to a 20", and seeing as how I got the motor for free I figure its worth a shot. It is turning out to be exactly the motor I was looking for besides the shaft length. Do you see this as a big problem? Does anyone know whats involved in the swap? What I'll need?

Whats a hipo style prop?

[Riverman]

Find a scrap V4 and use the mid and clamp from it. On the gearcase you will need to change the drive shaft and shift shaft. No big deal.

[CSD23]

Riverman, Do you know if I can use a 20" mid from a 88hp spl crossflow for my 140 looper?:confused:

[Riverman]

I know for a fact the gearcases are interchangeable, don't know about the mid. Racer would know. :)

Thanks!

HI. Sorry I used a short form meaning hi performance, mostly designed for greater top speeds thanks.
