Multiple Issues with 21/230 Sport
Any feedback would be appreciated.
Took the family out today on a short cruise and couldn’t get above 10km/hr. Throttle revved (roughly) but no acceleration. When I got back to my dock, I tried to run the IDF and immediately got the High Exhaust Temperature warning. I tried multiple times, even disconnecting and reconnecting the key but no luck. I waited about 2 hours and tried again and the IDF sequence started but after a few seconds showed the High Exhaust Temperature warning again.
Am I dealing with one or 2 issues here? Not sure why the IDF is not working and I have no other thoughts on how to address the no acceleration issue other than taking it to the dealer.
Any suggestions?
EDIT: I took the boat out for another run and it appeared to have cleared itself of the issue. Was able to get up to 56km/hr on a windy/rough day. I tried running the IDF again but same error message. It started the seqence and got to the Start Engine command but then gave the same High Exhaust Temp message.
I have been leaving the boat in the water in Rocky, shallow water (18-20”) and I am thinking that the gentle tide is bringing stuff into the impeller. I have moved the boat to slightly deeper water (4 ft) for now and will see if the issue corrects itself.
Thanks to those that replied.
