Correct craft strut reference chart

Long story short, I'm looking to see if anyone has a more clear chart than the one posted on CCF?

I'm trying to get a replacement for my strut on my 1978 Martinique. It takes the same strut as a 2nd gen ski nautique the SA154. My existing strut shows the number "AF2500-6"

Now I have to see if I can link the pictures I have of my strut and the blurry chart I found here on CCF.



Thanks,

And just to back up Steve's answer, here's a quote from an old thread

So does anyone know the difference between the sa/dv154 strut that I need, versus a strut from a 71 Martinique which uses a 6dv?

The strut on my 76’ Martinique is the af2500-6. Works fine for me.

KENO wrote: What are the measurements of your strut that you have now? Size of the base, bolt hole spacing, length of the barrel so that maybe somebody with a 6DV can measure and you can have something to compare to? Or somebody with a SA 154 or 154 DV or any other  can measure and you can compare to.

Great idea. I have a feeling that there are less different struts than we are led to believe, based on the chart.

Ok. Here numbers.

Based on my AF2500-6 which is supposed to be an dv/sa154 according to the chart.


Base measurements are 3.-1/4" wide x 5-7/8" wide

Bolt spacing center to center 2-1/4" short   side x 4" on the long side.

Barrel length of the strut is 5-1/8"

Did different struts use a different angle?? That's harder to measure since my original is pretty bent. I did take measurements of where it should be height wise from bottom of the base where it mates to the hull. Bow side = 5-5/8" to top of outside of brass strut and stern side is 6-3/4" using the same measuring reference.

A CCF member has a strut from a 71 Martinique and one from a early mustang. Both of those have the same AF2500-6 markings as my strut from my 78 Martinique. There two he has have different barrel lengths. 4-7/8" and the other 6-1/8". He has both those side by side and they are exactly the same except for barrel length which shouldn't matter.   If the only difference is the barrel length on these 3, then any of these would work, right? Most cutlass bearings are not the same length as the barrel.

That 5-5/8" measurement is estimated, because my original strut it bent about 25° however it's bent, not smushed. . So there's no way it's 4-5/8", unless the way others have measured. But I doubt it based on my measuremen might be a little short if anything, def not shorter than my measurements. . I'll check out that thread you likyed..
