2019 150 Mercury Outboard

by Mike
(Granby CO)

I bought new tritoon boat last season with a Mercury 150 outboard. Two weeks ago I would bring it to almost full RPS's then hear 6 audio tones and the motor would drop to idle. I have tried every Merc service shop in the state and no appointments are available until late September. In the Rocky Mtns, thats almost the end of the season. I called Mercury direct and they pretty much said tough luck.

Does anyone have any ideas?

I sure did learn a lession. If it happens just once, buy a boat and prepay for 5 months slip and then miss most of the season? A Mercury is pretty far down my recomondation list.

Possible overheating
by: Jay

Had that same issue on my pontoon with the 2013 150hp 4 stroke. Found it was over heating due to the fact the 3/4 pontoon was disturbing the water flow to the lower unit water intake. Mercury sells a part to add the the intake to ram more water into the engine. Solved the problem. Great engine 7 years latter. Good Luck.

Maybe tilt trim msensor
by: Jeff

Sounds like it's not getting the proper signal from the tilt trim sensor. Try unplugging in the engine compartment. then plug back in and cycle the power. This should reset the sensor.
