I have not read where anyone has really had a problem like this resolved, but I am going to put it out there to see if any of you smart guys know where to look.
I have a 2012 Seadoo Speedster 150 HO
I recently had the motor rebuilt and since I got it back, the boat has been hard to start when warm. I have full power and it runs very smooth on the water.
The symptom is as follows. I push the start and the starter starts the motor but it immediately stalls almost as if the RPMS are too low. Then I hit the start button again and it takes about 2 or 3 seconds and the motor starts and it sounds like it might stall at first but then it idles normally and all is good. Sometimes I smell the exhaust right after the start and it smells rich like unburned fuel. There are never any error codes thrown. I checked everything with the CanDoo and it all seems fine.
This will happen every time until the next day when everything is cold and it will start normally.
In the process of fixing this and from some recommendations I have replaced the following.
Injectors
Fuel Pump
Throttle body
So, to summarize. Boat runs fine and performs as expected but it is abnormally hard to start when warm and this all started after the rebuild. (guy who rebuilt it is never available so there is no going back to him)
Any Ideas? I was thinking may be the MAT sensor but......I am not sure if that would even cause this problem.
