progress report....or lack of it. Replaced expensive little map sensor
Started and ran ok saturday morning on muffs albeit it seemd to me to be a little lumpy.
Launched boat today, Monday, for on water test. Absolute b*!"%@!d to start which is highly unusual for this motor. Would only start with extra throttle applied and would only run with loadsa throttle on in neutral. Stalled as soon as throttle backed off. Sensor warning came up again with same sequence 3+2. As it warmed up it became possible to have the engine running at a lumpy tickover with throttle closed. Sensor warning would not cancel.
Never even got as far as putting it in gear and wasn't for venturing into open water with no back up. Boat winched out again and taken home. On muffs started fine, sensor warning still there but cancelled at first attempt. Ran at all engine speeds up to the out of gear limiter at 3k revs for a considerable period with no sensor warnings and smooth tick over.
Gonna try in a tub tomorrow to see if the exhaust back pressure in water makes any difference but it wont be as deep in tub as hanging off the back of a floating boat. Then go and chuck it in the water again when I get some spare time (whatever that is)
In the meantime the jet catamaran we run is having its own special jet sensor problems and a man who hopefully knows about these things is onboard at the port and is, as I type this, apparently replacing circuit boards. Hope he has more luck (and idea) than me
Tune in for the next thrilling and expensive
