1993 Evinrude 175 Looper

[imported_Z]

I am looking for opinions on the above motor. Looking to replace a 1990 175 Johnson V6 that needs rebuilding. Any historical problems with these motors or anything I need to look out for. I am hoping this would be a plug and play motor using same controls and gauges. Thanks for your help.

Yes, it's a direct replacement. But boy, will you be shocked at the difference!

in what way?

I take it from that, that the '90 motor is a crossflow and your gonna swap it with this looper, and you'll see a big difference in performance.

Yes, the 90 is a crossflow. Which motor has the better performance? How is it different? Is the 93 looper a better motor? I have been struggling between rebuilding and replacing, however the cost of a remanufactured powerhead makes me lean towards replacing. Maybe I should be looking at something more current. Any help is appreciated.

Re: 1993 Evinrude 175 Looper

i would choose the 60* 175,

reason is, its a fairly easy motor to work on.
its carburated so still old school.
the ois sound very fancy but its still cdi ignition. not computer controlled. just 2 powerpacks in 1 unit which can do some tricks like Quickstart and slow, shift interupter.
the only difference is it has a timing wheel with infrared sensors.
i do like it.

if you want to do some maintenence yourself this is the motor you should choose its better than the crossflow and not as complicated as EFI or DFI or 4 stroke.

but if you are looking for a smoother running engine and better fuel economy this 2 stroke still burns oil and is very loud compared to DFI motors.

hope this helps your decision.

Re: 1993 Evinrude 175 Looper

is the fuel economy or noise level any different than the current 175 crossflow that I have?

Re: 1993 Evinrude 175 Looper

fuel economy might be slightly better, but if thats a real isseu dont run a 2 stroke carburated outboard. crossflow or looper.
the problem with them is that at one point both ports are opened and effeciency is being lost.
with DFI "ficht" this problem is solved.
the 2 ports, intake and exhaust are still open at the same time for some period but there is no fuel in the intake. the fuel is being introduced after the intake and exhaust ports have closed by the direct injecter.

the noise between a looper and cf is probbebly the same.
the 60* looper starts a lot better than any other carburated 2 stroke.

Re: 1993 Evinrude 175 Looper

The 60* looper will be quieter than your old crossflow, will get much better fuel economy and have much more power. Comparing the two on the same boat, set up the same -- you'll probably be able to run a prop with more pitch.

Set it up at about 6000 rpm with an average load. You'll be impressed.
