Zodiac Hurricane 733 - Debating single Yamaha F-300 or twin F-150s

We're building out a Zodiac 733 and debating on whether to go with a single Yamaha F-300 or a pair of F-150's.
I have a couple of buddies who have the same RIBs both running the twin F-150's and they're awesome but I think I would be good and even more economical running just the single F-300.
After owning outboard boats for the last 40 years Iíve only had one catastrophic failure (blew up an old 2 stroke) that left me in need of a tow.
I often go spearfishing up to 60 miles offshore but always subscribe to Vessel Assist towing that is good out to a 100 miles anyway. Never had to use them yet.
Curious if anyone has used a big single on this RIB (or similar) and what their experiences/thoughts are.......?

When I built mine I talked to the folks up at Hurricane and they were not supportive of going over a single 250 so thatís what I went with. We dive the Channel Islands with usually four people. Boat rides like a dream and get 3mpg up to about 30mph. Click image for larger version

3 mpg at 30 is nice. What about your max speed?

Before the t-top I hit 50+, with t-top and a load of people it tops out about 46mph or so.

That's impressive too. That's right about what my buddies with the twin Yamaha F-150s get.
Are you completely satisfied with the Suzuki?

Also, when you guys go diving are you using any type of a ladder or just crawling over the tubes?

Twin 150 Yamahas and I've seen 52 mpg in a friend's 733. Faster than I'll ever need to go (or be able to).

733 twins or single

I've spent quite a bit of time on 733's with twin 150's. Twins are far more maneuverable in close quarters. As well, I have experienced a loss of one engine when out but was still able to get up on plane and get back to the dock. That was a rescue boat. I'm intrigued by the reviews of the Evinrude high output oil injected engines. More power and better fuel economy. No direct experience though.

Iím totally satisfied with the suzuki. Itís quiet, smooth, runs awesome.

Twins definitely have advantages and disadvantages as well. I remember one person pointed out that two engines doubles your chance of something breaking :-)

I have a ladder. I got it from a local stainless guy who made one for another customer who never came back. Itís mounted on a bracket welded to the transom cap.

Great boat. That pod adds a bit of length. You can call it an 800.
