?? X Dimension

#1 03-19-2004, 06:48 PM

ok ok calling all you outboard V20 owners.........i was asked by the guy that is going to rig my motor when the boat is ready. WHAT the X dimension was?????? he said it was the distance from the center of the bottom of the boat to the center of the prop shaft. had never heard of that before.........................if by any any any chance anyone knows. i'll owe you a beer. all kidding aside if anyone knows this one it would help.
thanks ken

My guess is that he is asking you what shaft leanth you need?? Which is the top of transom (center) to bottom of the boat.
Or from the motor bracket were it sits on the transom to the Cavatation plate (above prop)
This will give him the shaft leanth of the motor.

I hope this is it?? other wise yopu will need some one wiser then I!!

I have never heard of that measure before?? you can change the distance from boat to prop by timming the motor??
When you find out let us no, as I have never heardof this before and I converted my boat to a outboard motor and never considered this??
But it works fine.

I've never heard of needing to know the distance from the center of the bottom of the boat to the center of the prop shaft. I have heard of the "X" dimension though. I think MJ is on the right track. What I thought it was (and I may be wrong), is the dimension from the top of the transom (at the point of the motor mounting) to the lowest point on the keel. The motor needs to be set at the correct height which generally puts the cavitation plate at approximately 1-1 1/2" below the keel.
You may want to ask the question on The Hull Truth site or iboats.com to see what they can offer for assistance.
Otherwise, you'll have to ask him to clarify.

hey chum,
i think you got it. he said the lowest point of the keel to the center of the prop shaft. that is what the x dimension is..................i guess..........you have to excuse me i'm polish, sometimes it does not comput ;D

Well I thought the prop is under the boat??
The prop shaft and keel never are inline with each other! The cavation plate is in line with the keel.

maco,
i guess you take a straight edge to the bottom of the keel and extend it to the lower unit, then you measure from the straight edge to the center of the prop shaft. that is how it was explained to me. ( i think ) if this is the only problem i have i'll be happy
thanks ken

I am glad you found out!!

Now tell me what the heck is that measure for?? If the cavation plate is even with the bottom like it is supose to be what that measure mean??

Not trying to start anything but I really like to no what this has to do with the price ogs in Mass. ???

MJ, that's the whole point. The cavitation plate is NOT supposed to be even with the lowest point on the keel. It's supposed to be a little below. 1"-1 1/2" I believe.

Hey BTW, not to hijack this thread but, MJ, do you read any other sections on the site besides this one? I posed a question for you in the "Off Topic" section. ???

I try to?? If I see a post of the day. I come here 20 times a day and look for new post. I must have missed it.

Any way I am still wondering about this measurement??????? You no I am not the brighest light bulb in the bunch!! :-[

We know that! That's why we try to be patient with you. ;D ;D ;D
