    Hondas 150 HP stalling at idle.

    Hello everyone. I have twin Hondas 150 hp, purchased around 2021 with 2,400 hours. Both are stalling at idle, needing a bit more of crank time to start, or stalling once you slow down into idle. The RPM's seem a bit to slow at idle, specially on a cold motor. The spark plus are new and on one of...

    Honda 150 hp rpm's oscillating.

    We swap the valve between two Hondas 150 and the problem moved to the other motor, and the one that had the problem starting to work good. I just ordered a O2 sensor. Thanks for you help. Allois

    Honda 150 hp rpm's oscillating.

    Thanks. Expensive part. I might swap between other Hondas 150 to find out if that is the problem. If yes, then I will buy a new sensor. Thanks. Again

    Honda 150 hp rpm's oscillating.

    Would it be this sensor? Part 16 on the diagram? VALVE ASSY., AIR BYPASS 36163-ZY3-003 Also, I just changes the entire module with the fuel pump and vapor separator and nothing changed. Thanks.

    Honda 150 hp rpm's oscillating.

    Thanks for that tip. Is the O2 just a sensor I can buy and replace? Looks like more 5.000 rpm. The problem since to increase over time. Thanks. Allois

    Honda 150 hp rpm's oscillating.

    Hello everyone. I had a few Hondas 150 hp over the years. On two of them the rpm's oscillates around 1,000 rpm, up and down, when going between 2,500 to 4,000 rpm. I did change the fuel pump and vapor separator module and nothing changed. Any ideas of what causes this problem? Thank you, Allois

    Hondas 150 HP overheating at 5,000 rpm

    I did install the new thermostat (two off them) and all other new parts. No o-ring for the bottom part. Instead they say to use liquid gasket on the bottom of that plastic mid section. A few drops of the liquid gasket fell inside the chamber as the liquid gasket is on the bottom of that mid...

    Hondas 150 HP overheating at 5,000 rpm

    Hello everyone. I have 4 Hondas 150. Out of them 3 sound the alarm for overheating and go into the safe mode at 5,000 rpm. All pumps work good and water pressure seems ok. Could it be a thermostat issue? I live in a very hot place. Water temp always around 86*. They used to run at 6,500 rpm with...
