Ribcraft 6.8 final update and last chance to change spec

Hi

You all helped me well with the spec of my 6.8 Ribcraft. (see my previous topics)
I now have the drawing here: http://image82.webshots.com/182/9/14...3RzRldg_fs.jpg

This will be the last chance to make minor changes or additions before it will go in production.

I am still in doubt about the engine size should it be 175 or 225 Hp and extra patches more up at the front.

Please comment

Boat will probably at the Southampton Boat show in mid September.

Cheers

Q.

Q.
WEIGHT and handleing not horses[within reason] would be my main limiting criteria.Ribcraft make a truley great RIB,they are very solidly built,as a consiquence are heavier than some,and in my experiance do benifit from a few extra horses!!

I got "overall patches" on mine, and to put none to fine a point on it, that section is probably the best preserved bit of my 25-ish YO tubes.........

Unless the 225 is spectacularly heavier / more expensive than the 175, I'd go big!

If it's the same block, 225. If not, 175.

i would also say go 225. We went for the larger of the two choice of engines on our 7.8 ribcraft and its worked well - plenty of power when you need it and you dont have to rev it that hard so fuel consumption has been a pleasant surprise...as much as it can be a pleasant surprise running a large outboard!

Plunge into debt and get yourself some scotseats - awesome!

seen a 6.8 with a 225 on over the weekend , it seemed quite heavy on the back , didnt handle so well,just didnt seem balanced right, i've taken out a 6.5 redbay with a 175 suzuki on and loved it , very smooth engine and with 6 people on went 42knots no prob ,also took out a 7.8 ribcraft/tornado[tornado hull everything else ribcraft]with 175 suzuki, and was really surprised how well it preformed, 40knots with full tank and 5 on board, so i think the 175 will do everything you want it to do and keep it well balanced, wouldnt put the 225 on unless you where going to be bringing heavy loads
