In regards to a 5-blade, go for it. Yes they are harder on the drive because they bite more, but with a 710 and the TCM XR drive, you shouldn't have a problem, its a strong drive. The 2750/800 combo was running a 30p P-5X so I'd say yours should spin a 27-ish 5-blade.
Good luck and keep us updated with pictures.

Hello Uncle Dave:
It is coming together quite nicely---your dream is turning into a reality.
On prop selection Airtime hit the nail on the head--- the 5-6 blades are tough on drives. Tomorrow44 is right if you boat on a lake you could get away with a 5 blade---but the gear sets [upper and lower] are still Mercury gears and when you have too little slip something will break and you will lose a tooth or two on a gear set and may not get back to the dock. No thanks, if your 20 miles off of Long Beach in a single engine boat.
I recall you indicated you would primarily use the boat in the ocean hence the radar and 3d aspects of your navigation system. In the ocean the 5 blades really bite hard-er and the water is really dense and props hook up good. I won't even mention when you go over swells quartering away and driving over or with the swells at speed--- where the drive loads and unloads the lash on those gear sets constantly. Add the extra bite of that other blade and your gonna have problems---prop slip is your friend use to your advantage.
I would take it easy and put a Bravo I prop of your choice on the boat start with a 28 and go up or down depending on your driving style and weight/power combo and WOT-- RPM's. I bet you go lower in pitch if anything and don't forget to look at the Mercury Revolution 4 props they really work well [I believe you can get a 25Pitch now and the Revolution is usually a bit taller ie... a 25 is more like a normal 27. Talk to the rep. at Mercury propeller division they will answer all your questions.
Thank you, for sharing your awesome build with us your hard work and effort is definitely showing in the end result

In time for X-mas
Thanks guys - I've been in New York all week and have to head up to Montreal tomorrow night and will be out of town another week so I havent seen it in three weeks now. I was drinking martinis in my pool a week ago- not quite the same thing here- my nipples could cut glass walking to the office.
Chris @ Lavey called me and basically told me were ready to go.
The interiors done now and they were going to have the furuno guy come over to bless the electronics install and run some tests then they'll do a lake test to insure everythings as it should be, and I should be picking it up next weekend. Ill post comprehensive interior picts and lighting picts at night.
All good info - I'm going to be pretty conservative for the first couple hours in any case and I appreciate your and airtimes feedback on slips effect on the drives, but I think there is actually even more to it than the blade count that's certainly a variable I can control as opposed to the hull itself which contributes to some base amount of given % of slip no matter the blade count. Im used to running tunnels and cats which seems to be inherently more efficient than v's
My tunnel routinely computes out at about 7-8% slip with a 4 blade and Ive not stripped any teeth even with an older B1 before I had the B1-Xr and Ive had some pretty serious loading and unloading but then again its a much lighter boat with only a 500 HP small block. Its a rockin machine but I want a ride in that Howard deck boat with a taylor engine for sure!!
I think its going to come down to the same thing it always does with me and that's my own ability to restrain myself - which IS an issue.
Im going to check out the revolution wheels youre talking about thanks for the info. Ill see you in San Diego for that tour of Coronado and the islands soon Kap.
Thanks everyone for taking the time to look at the picts.

The extra blades will make it easier to deal with rough water at the speeds you'll actually be able to handle. More is really better in the ocean. The loads on the prop change a LOT as you pass each swell. Highly loaded, but high X dimension 4 blade props will just keep blowing out. The 5 or 6 will blow out a LOT less.
If the boat was 47 feet long, instead of 27 feet, then you'd be able to boogie hard and fast and long enough in big water to blow up drives in the ocean.
If you had a stripped out race 27, then you could. But all your gear, batteries, and friends will break long before the drive.
At least, that's my experience. YMMV.

The final product
Minus a few tiny things being tweaked. Netx week we splash.
I know its mine, but this rig is seriously Phat.
