Re: 2000 150 Yamaha EFI
is this OX66 EFI or HPDI ?
post the model number.
also look at all the maint records, if the maint hasnt been done on the hourly OR calander basis as per the maint manual you may want to take a mulligan on this one.
trust me on this one.
I am fighting a commercial use F225, book says every 200 hours or yearly inspect the water pump. engine went 2 years and 700 hours without it, the driveshaft splines are now hung in the crank splines and lowerunit OR powerhead removal is now impossible.
I lifted the transom of a 28' parker off the trailer by the powerhead,heated the exposed part of the driveshaft just below the powerhead until it glowed red several times and hit the shaft with a dulled air chiesel to viberate it. it hasnt moved a mm.
motor was placed in service in 05.
is it yamahas fault or the customers for the lack of periodic maint as per the schedule ?
