Great Question! They have not done one on the 33 AT yet. All of the 33 AT's have 525EFI's. My buddy is a Donzi dealer and he has done it on 3 35 Donzis and he gets 5-6mph on top and about 3mph in the mid range on each with the CMI package. I would assume it would be comparable on the 33 AT since they are about the same weight. You are probably looking at a mid to upper 80's boat. The great news is that Mercruiser will warranty it up to 5 years if installed by the builder. It will cost you about 6K-7K for both engines.

One of these!

To me the 33 w/496HOs and CMIs is the perfect set up. Priced right/warr-5yrs/ Ins-cheaper by a long shot over Blue motors/ Good speeds/ HUGE cabin(if you use it) Just can't go wrong with it,perfect boat

I agree with cosmic on that and if I could just find that money tree I will have one of those before the end of this year.

You need to get rid of the goats. If one does sprout near you, they will get to it first; just like a wife.

6 MPH with a set of headers alone?

Rippem

I've called BS on that before

that equals enough power/RPM to go up 2 inches of pitch min.

pretty amazing for 35HP a side

I have never been in the Donzi. That is what my friend tells me. It gets more than 35 a side. You are looking at 45 a side. That’s 90 HP.. Most step bottom boats gain 1 mph for ever 12 to 13 HP. Plus you go up in prop...He is running 32 labbed bravos vs 28 stock bravos. Build one and let’s see...

condidered it. As I had my 353 sold to another board member.

but... I'm 6'5" and hang out on my boat/stay aboard alot.

The minimized cabin and sunpad of the 35ZR just won't cut it.

I think he ment a 33 A.T.
