Ya Gotta love vintage shovel nose hydros.
Good choice for power, but keep your voice down some folks round here don't appreciate smelly noisy Zenoahs.

I have had my eye on that boat and the easy vee which looks really simple for a big boat kit but the vintage hydro look is awsome.

[Flying Scotsman]

Doug, do you have plans for hardware, as of this date?

They aren't going for it. LOL

The motor, mount, pipe and header arrived today!!! The exhaust er eh, electrons, will exit the transom.

I'll be putting the deck on next.

Doug

[G Doggett]

Looks like you have tons of room to fit the engine and exhaust in there.
Will the carb be under the deck line ?
I had a hell of a job squeezing everything into Miss Zenoah because it has a much lower profile deck than yours.
The main reason I made the dummy exhaust stacks was to disguise the bulges for the header pipe and carb.
Keep up the good work.
Vintage hydros rock.
Graham.

[Doug Smock]

Yes sir, everything will be hidden away. I will have to put short needles in the carb, but other than that I should be ok.

I'm getting excited!

Doug

Graham, post some pics of your Miss Zenoah, I love to see what other folks have done.

[Jeepers]

wow! that motor looks tiny in that thing!
