    2008 F250TXR code 72?

    Last year I limped home. It sounded BAD. It was obvious a major internal problem had occurred. I did a compression check they all came back about 150 cold. I Took it apart I could see the crank /thrust bearing failed. I got a new crank and did new bearings throughout. I put in a new oil pump as...

    code 72 was the only new code... the others were not since the engine rebuild

    2008 F250TXR code 72?

    Nope. I got on plane with my computer hooked up and even after the alarm went off and it went into limp mode the software didn't really say what was wrong. It logged code 72. Seems ridiculous it can go into limp mode and not log something more than that.. like overheat or low oil pressure.

    2008 F250TXR code 72?

    Okay... here I am again. From the beginning now... Engine blew a bearing last year. I rebuilt the engine. After getting it on the boat it seemed one side wasn't firing. I could disconnect the injectors on the port side and it made no difference to the engine RPM. That is now fixed I'm not %100...

    Interchangeable lower units??

    Thanks for the reply... and I think your right. I read on another forum that the lower water pickups were for cooling the front bearing. Had nothing to do with better cooling of the engine itself.

    Interchangeable lower units??

    I have a 2008 Yamaha 250HP. It has the additional water intake passages. I replaced the lower unit with one that was a couple years older that does not have the secondary water inlets.... I am having a problem with it overheating.... could this be a contributing factor??

    2008 F250 4 stroke. low compression / bad am phaser?

    Found the problem. I must have let one piston slide down and smack the spark plug when I was changing the bearings. It bent the spark plug to zero gap.

    2008 F250 4 stroke. low compression / bad am phaser?

    Same problem. That wasn't it. Guess I'll replace all the plugs. If that's not the solution I have the software getting here Tuesday so I can try and isolate the issue. I throttle up... gets the boat on plane... but I'm into throttle a lot more than normal. It then struggles to stay on plane...

    2008 F250 4 stroke. low compression / bad am phaser?

    I'm not %100 sure on the hours it was my dads... he got it used. As I recall it was considered 'low'. I took off the OCV... looked clean. Tested it with12v it moved. Took the cap off the phaser and CAREFULLY put some pressure on the banjo bolt... I felt a small 'click' like it might have been...

    Yamaha 4 stroke timing

    Obviously might want to triple check your tensioner is working correctly. If it is it's almost impossible for it to jump teeth like that.
