What exactly is "X" dimension? I know it has to do with drive height but that is about it. Thanks in advance

That is what I thought but someone in the prop forum said they has a 15 1/4" X dimension...is this possible or was he in error?

On a sterndrive the term refers to the crankshaft center line or the drive input shaft center line which should be the same On an outboard I don't think the term should really apply

And all this time I thought it was the size of the filing cabinet on "X Files",,,,,,,

I had to read that about 5 times to make any sense of it. I'm not the best with spelling or punctuation but you realy need a period between those two sentences.

On a sterndrive the term refers to the crankshaft centerline or the drive input shaft center line wich should be the same. On an outboard I don't think the term should really apply.

The distance from the bottom of the boat to the crank center line, not the prop shaft center.

OK--help me out here with the X dimension mystery--

On my SR357--distance from CL of crakshaft to CL of propshaft is 26".

The distnce between bottom edge of V in front of drive(s) to CL of prop shaft is 9".

TRS Drives are spaced 33 1/2" CL to CL.

Do any of these measuements mean anything?

Is prop "deep" or shallow -- or what--

Thanks

The distance from the crank center to the prop shaft center will always be the same of course unless you start altering the drive itself (like installing an Alpha SS or an Imco shorite or spacers). The X-dim measurement is used when installing the engine/transom assembly and it is the distance from the bottom of the boat up to the crank centerline. The bigger the # the higher your drive will be.
