Much appreciated!!! Yes, I'll post here as it progresses. Pinging an engineer friend to look at some material/strength numbers for me.... I'm ok with building part of it as way-overkill strength, but of course if 15+lbs could come out of it by aluminum VS steel and thickness of some of the...

Yes, no need to pass 6000rpm. If it had to idle nice to make a bravo/etc shift gently it'd maybe give up say 40hp@6000 and 30 @5000. I know I'll have to watch alignment, but if it's a double cardan/ CV at the front of the shaft the same as what's stock at the rear of the shaft, it won't be...

I certainly have more time than money--- and I do like fabricating... We'll see if it turns out I have as much sense :) If good usable bravo drives were about half the cost they currently are..... I could see going that route.

From the transom forward, it should be similar weighted as if it had a big block, I should have maximum of ~3.5" of the transmission poking past the transom. Velvet drive would have poked through about ~1/2" by my measurements. I'll have a shaft made with a u joint at one end for the trans...

It looks like he has given them a work out, for sure!!!! I'll very very rarely see rough water---(Haven't done LOTO in my own boat yet but plan to with this one maybe 1x/year) but agree that I'm conscious of the weight and where it is . I see where I can trim a bit of weight on the exhaust...

Yes, small block power. If I don't get into a second boat with twin power, I'll want to turn this one up to ~550hp or more. I'm making enough space with the extension box for BBC+TH400 from the start although with more torque I wouldn't necessarily use another gear so I'll hang onto one velvet...

Excellent information, and I agree, it's a big change and usually wouldn't be warranted. Some part of it is wanting to try things, and what most say they end up with after extension boxes seem to be some good advantages---- besides me needing it to fit the longer drivetrain in. Please check...

I bought a 24' Mariah without drive/power. Single engine at this time... I'll be running ~450hp with a TH400 set up as a two speed--- and am making an extension box to convert from bravo to TRS and to able to run the prop a bit shallower--- TRS is tall! 1.46 trans ratio 1.50 drive ratio --- I...
