    Engine alignment question.

    Hello. I don't seem to be able to align the engine to the bearing housing assembly. It looks like the engine coupling is too far right from the bearing housing coupling.

    Do I need to re-shim intermediate housing to get it fixed?

    Re: Engine alignment question.

    Have you had the pump, and mid shaft out?

    I find them to be WAY off from the factory.....

    We use the Cold Fusion alignment tool. IMO This is the ONLY way to align a Yamaha.

    You need to pull the engine, and mid shaft. You mount the tool to the bulkhead, and align pump until the insert slides onto the shaft and into the plate like butter. This is where you will determine "if" you need shims on the midshaft hosing.

    Last, you shim / move the engine around to get couplers aligned properly.

    Doing it ANY other way, you risk shaft spline, or midshaft damage.

    Re: Engine alignment question.

    I did have pump out years ago, when I replaced impeller and it's housing. I had bearing assembly out now - replaced and rebuild. Intermediate housing were never touched.
    Another tool - my wife gonna kill me!

    Re: Engine alignment question.

    The tool is very nice, but I have years and years on skis aligned by eye and feel with no issue. He's not working on a $30k boat here... If the splines look good, just reinstall the midshaft the way it was, and align the engine to it.

    That was kind of my question - how this should be done? I can see how I can move engine up/down, a little bit left to right if using shims only on one side, but I need to move the engine more to the left without increasing the hight, so how can I do that?

    Re: Engine alignment question.

    A question when u set this up to be aligned did you tighten all screws down all the way on your motor mounts ( bedplate to motor mount )?? , and are there any shims on your motor mounts ??

    No I didn't tighten the screws, just thread them in the holes to hold the shims. Don't think that tightening would do any major movement if any at all.
    Currently I have 2 shims at the PTO right mount (looking towards the back) to raise engine and move left, but still looks like need to move left more. Just trying to get into the ballpark before more precise alignment.

    Re: Engine alignment question.

    Just wanna clarify. If I'm gonna decide to purchase the Cold-Fusion tool - I need to remove the Bearing assembly (3) and Intermediate Housing (6). And the tool installs in lieu of Intermediate housing (6) - correct?
