I/O (Sterndrive) Conversion to Outboards

[Pmt133]

It was just a curiosity more than anything. I have seen the occasional transom with 2.25" core (3x 3/4 sheet core vs the normal 1.5 and layup). I wonder if it was just a selling/cost saving point and nothing more. I agree that it doesn't add anything. There are some out there for whatever reason though.

I've been a semi retired shiftless bass turd for about 5 years. 8 think next year is cutoff for me as grandkids are starting to pop.

Mamma has another five minimum. I need her to support my boat habit.

Been retired 8 years but have worked part time throughout. Wife just retired. It's nice to have time, which is one thing money can't buy!

More progress . . .

I got the exterior panels cut an installed. Lots of measuring and odd angles . . . my head started to hurt.

I'm letting the 'solar curing' do its thing.

I got to start thinking more about the internal structure. . . stringers, gussets, bracing . . . that sort of thing. Box structures are weak . . . a triangle is the strongest shape.

Isn't a circle the strongest?

No, a circle is the roundest shape

That was pretty much day 1 in Engineering school . . .

"A triangle's resistance to deformation is fundamental to its structural stability, making it a common shape in trusses and frameworks. Engineers use this property to create strong, lightweight structures by ensuring applied forces result in tension or compression along the triangle's sides."

I just don't want 'busy-up' the internal structure too much. Since the structure is about 3 feet tall, I'm also thinking about impact buckling . . .

Maybe a continuation of existing stringers thru the transom into the addition?

But if I'm putting a pipe thru a beam, round is best?

I've been looking at some twin engine brackets to see about the internal structure and hopefully get some ideas.
