We have a pontoon boat with a new Honda 4-stroke on it. The motor idles
fine and revs in neutral but as soon as we put it in forward or reverse gear
it cuts out. Is there some special switch that is out of adjustment???
Modern 4 strokes have a lot of sensor driven electronics. They are
difficult to troubleshoot without the proper diagnostic equipment and
software. I'd take it to a dealer if it were mine.

depends on whether its a big 4-stroke or a little one. On a smaller
motor, this might very well be a matter of slightly adjusting a
needle screw on a carbuerator.

I vaguely recall a Honda ad that indicated engines down to 40 hp would
be available with EFI. But there still are plenty of Hondas of many
sizes available with carbs or, "venturis," as Honda calls 'em.

I stated earlier I thought it was the throttle position sensor. I had
the exact same symptoms on my Yamaha 225 and 150 until the mechanics
found the sweet spot on TPS adjustment.
