Todd, that’s what I am seeing as well just wanted to confirm with Brian before I take skill saw to my newly finished transom. >:(a

Yes, measured on the OUTSIDE of the hull, assuming your 'aft transom' leans aft at 14 degrees like the original transom would have, the measurement from the bottom of the 'V' in the hull to the cut-out in the standard transom is 25-1/8".  It would be 25" exactly if the transom were vertical, but with a little bit of trig, you can see that the hypotenuse (measurement of the distance flat on the outside surface of the transom) is actually 25-1/8".  Your new 'aft transom' should also measure 25-1/8" from the 'V' to the top of your motor mount, measured on the transom.  What does it measure right now?

Almost 27 inches. I could use a jack plate to lower it but that’s just another $300. Arrrgg. I have to blame you for this Brian, the only reason I measured it is because of your question about the swim step heights, 😂 . I’ll post some pictures of what skill saw does to a finished transom.

By the way good word “ hypotenuse” , that’s a new one for me.

Well ... technically, the dimension in the design is already adjusted to place the cav plate just barely into the water a little.


Example)

h cos(14) = x, where x is the shaft length and h is the measured distance on the transom itself, the hypotenuse. 

h = x / cos(14), which is 25 / cos(14) ... which comes out to about 25-3/4" inch. 


There's a little more than 1/2" downward adjustment in the 25-1/8" measurement to make up for minor motor mounting errors.  It's better to be down 1/2" than to suck air ...

PS: It's better to have to remove a little wood than it is to add!

Ok now your just showing off!!

[Brian.Dixon]

Ar ar arrr.....   Trig is one of the most useful types of math.  You don't have to remember it all either, just basic triangles, cos() and sin() stuff.

I can taste the salt air..... almost

Sexy looking boat!

Lookin good! I like the wood rails on the roof.

[Farmboy]

Outstanding!

Another big step

That is a beautiful sight!  I cant wait to see it in the water which looks to be soon and I am amazed how fast your boat is coming together.

Looks like you trimmed the motor mount and have the anti-cav plate lined up pretty good?  Is that bedliner coated on the motor mount?  Good idea!
