2005 Mustang 2200 ClubSport (LOA 27.7)
5.0 MPI
Bravo II
Closed cooling system
name : Sally (Mustang Sally!)
G'Day!
We are having an issue that could be related to each other
Our 2005 Mustang - 5.0 MPI -Bravo II had been sitting in the water for 5 years, we took her out without starting - have changed out her risers, checked manifolds, changed out leg impeller, gimbal ok, fuel and oil changed out - filters changed
plugs and leads all tested fine. - no osmosis and antio fouled - now stored in a SeaPen
She idles perfectly, although her taco and volt meter do not work.
On her first run- 0-5knts -fine
6 knots- and on throttle up- runs for 5-10 seconds and we get a solid alarm
the handheld read- 100% available power- just before the solid alarm the Guardian feature kicked in and she hesitated until almost stalling....handheld read 4% available power...pulled back to neutral and back in gear at low idle - no alarm
Fuel pressure before start up 40-solid no fluctuation
when Guardian mode kicked in it raised to 50...then we lost fuel pressure for 2 minutes..then it returned.. so we changed out the fuel pump today- hooked her up to the handheld.....same issue!.. 5-6 knots..Guardian mode.- sits on 180 (closed cooling system)
Any ideas what it could possibly be?
This is where it gets interesting- the dash hour meter reads 89, but the ECM reads 268
The previous owner - has owned the boat since new - and assures me nothing has been changed out - hour gauge or ECM.- no reason to doubt him -
This leads me to my next question - When we hooked up the handheld it does not give us any serial numbers we can tie up to the boats engine, leg or VIN, is there any mode that does this, or can Mercruiser extract serial numbers, -( we are in Australia, but my Mechanic is heading back to California on Wednesday for 3 weeks, I am thinking about him taking the ECM for testing in the US, for faults and to extract any serial numbers to confirm boat of origin)and tell me if the ECM is original or has been swapped out for a defective ECM (with higher hours) and my low hour ECM put into another vessel.
Any help on wither questions would be greatly appreciated.
