I had no intentions of re-powering as my boat runs great but a guy who's sponsored by Yamaha listed these for a price that made me run down South and buy them. The Century 2900 Express has the same beam, loa and weight and gets 1.4 at cruise. I have an intimate knowledge of CG and the 290 is very sensitive with respect to balance. Just changing the battery location and adding a pair gave me a noticeable improvement in hole shot and mpg.
I believe these V8's are ment to be on this boat, she's gonna run like no other

Actually they're 804 lbs dry each but my boat can take it. Plenty of beam, the bow curently sits slightly down and the transom is easily strong enough. Someone has to be the first

nope, I should see 1.5 cruise and I hold 225 gl. not quite as far as I really wanna go but it's a huge gain in the right direction

Its interesting that you're falling off plane at 27mph. I can stay on place, with a decent load, down to about 23mph. Did you have the 4.2l F250's?

Regardless, you'll have an awesome riding boat with the 350's. Looking forward to pics and test results! Good luck!

I also have a costal 290, 2007 model and was thinking of moving the house single battery to the centerline in the Genset area as I have room with the generator in there.

Currently there is a single group 31 and am going to upgrade to two straddling center line.

Any gotchas or issues you came into when you did this?

Thanks

No issues but I did add a pair and decided to change the wiring around so the way I now have it is House 1 & 2 and Starting 1 & 2 plus one for the Gen. I only have a 3 bank charger so I'm definitely running the secondary charging wire so all 4 batteries will charge when engines are running. May end up installing a two bank just to be covered if I need to.

I'm mainly having issues in rough water. When I'm not fishing and just cruising around I can run 23 mph before I start losing plane. I'm hoping with the amount of torque the 350's have I will be able to slow way down in the rough stuff but still have enough power to keep her in control

Don't listen to them...!!!

I have the F350s on my boat and switched from triple Merc Optis. I also removed the SS XL props and added the Enertia Eco props for a HUGE difference in mid-range cruise speed and RPM. I have never seen a 1.7 mpg cruise, EVER!! The holeshot is unreal compared to the Vrods and I would rather make my torque at all RPMs than just when under boost.

Headed back to the shop for day two of disassembly, 220 & scotch brite pads... i'm getting faster prepping these motors for paint but damn, it takes a while to get it all scuffed & cleaned but if you want it right you need to scuff every surface.

What size Eco's fit the V8? The Yamaha Props are larger hub. Mercury must make a F350 hub kit I'm assuming?

Default Did you modify the live well?

Did you modify the live well to have a transparent window in it?

Or is your boat just newer than my boat??

Thanks
Eddie

They all had this setup until 2004 when they change the seating arrangement. You must have a newer model than my 2003


Come to think of it, I think the window was an option on the early 290's

Hi Rob,

Engines look great man. Can't wait to see this run.

I currently have 275 Verado's on the boat I'm about to take delivery on. Thinking of flashing them to 300 or 325 hp so looking forward to seeing your numbers.

Currently rebuilding an aluminum trailer to get it ready for the boat.

Can I ask a favor? If you have a minute would you mind measuring the height of the top of the bunk from the cross member? Are those 8" or 10 " L brackets... and what is the distance between the bunks?


Appreciate the help, your trailer looks very similar to mine so the measurements will give me the best chance of the boat fitting on delivery.

Thanks
Jeff

I'll be at the boat shop tomorrow. I'll measure it up for you.

Removed the helm today so I can finally get to all the wiring and clean it all up nice. New bus bars, new uflex power assist steering and had a new stainless panel cut out to fit the new Command Link Display. Picked up the new Command Link Plus DEC Rigging Kit yesterday, HOLY CRAP that shizz is expensive. I'm excited to get her back together but it's going to be a few more weeks. Work is busy as heck, we're fishing the Wahoo Smackdown in Bimini next weekend and Thanksgiving is right after that. The soft spot in my floor is also expanding so I may as well cut the cockpit out and re-core it while the cool weather is here. I will most likely pull the gas tank while the floor is out. Inspection and coal tar epoxy will go a long way. I'll take some pics tomorrow
