Hey everyone please help

this has happened twice now driving it for a while and just cuts out first time we had pulled up on a sand bank and boats went past and wash was comin up on back of engine. it started fine then we drove for bout 200m and it cut out and didnt start again wasnt kicking over or trying. took it to mechanic said it was power pack so we changed it plus a new battery and i was off. This time i was towing a friend on the tube and he fell off , wake came up as we slowed down and went to start it once we were in the boat and nothing wasnt even tryin to kick over again... when i got home put it in the tank and it started first time.

then next time i wanted to try it in the river soo took it out and just drove making sure the wake wouldnt come up and flood the engine which was my thereoy mind you this is my first boat and havnt had it long...but sure enough the boat was fine drove for bout 30 mins then turned around for home and bout bout ten mins from home the small round box near ignition started making wierd humming /buzzing sound...is this the over heating buzzer???and what is making it cut out any suggestions are much appreciated

Re: Chrysler 105 stalling problem electrical

The buzzer is the overheat indicator AND if you are overheating it to the point that it stalls, you have done major damage to cylinder walls. Let's hope not. Run a compression test. Anything over 100 is good but if you have one or more cylinders around 30-50 psi, then the cylinder walls are scored and the engine needs a rebuild. If the buzzer has gone off, chances are excellent that you need to replace the water pump impeller. Not costly and not a big job--if you are handy with tools. See the top sticky thread. It is for later one piece lower units, but your two piece lower is very similar.


You may not be able to find that impeller easily, so if you want to order one, go to Franz marine at the Chrysler Crew site.

Second less threatening possibility: The wire loom goes up over the block, under the flywheel. Sometimes the wires are loose and they can bounce up and contact the flywheel. They will wear through and short out the circuit breaker. Everything stops and the engine won't even crank over. Ten minutes later, the circuit breaker cools and the engine will start normally and run until the wire again contacts the flywheel. SO: check for frayed wires under the flywheel.
