Welcome, Bill! I can't provide the exact answer you are looking for. For my 290, with the twin 350 5.0L engines, we ran with 4-blade stainless 19" x 20P 'Sea Ray cupped'. That setup was super responsive and worked well for the boat.
Hey Bill, I have the same engine setup and the PO put 4 blade 14 3/8 x 18 (I think, it’s a little hard to read and sorry it’s upside down). I think they are great around the dock and we hardly ever get over 2500 rpm at about 10 mph. We can run the entire length of Lake Norman, about 26 mile round trip on about 1/4 tank. Boat struggles to get to WOT rpm. My .02Hi everyone,
New to the forum as of today. Great info that's been shared over the years on the 290! Something that's come up a number of times has been re-propping from 3 to 4 blades. 2nd summer upcoming with my 290 with 3 blade props and thinking of moving to 4 for the reasons many have posted about previously (holeshot, lower rpm cruise). I have the 4.3ltr with Alpha 1's. I'm hoping there might be some good advice from the forum on optimal size of 4 blade to run with this configuration. Any help is appreciated!

Tacoma did your 290 have 5.7s or 5.0 engines? I ask because I am dying to add four blades to my 5.0s on my 98 290 in a couple weeks… I was thinking 17s or 19”p would work well…Welcome, Bill!

I need opinions..... Going to redo my whole canvas and don't know if I should keep the beige, or swap to black. Does the black have downsides, like heat, Salt Stain, fading? The Beige photo is my current canvas the black is an internet search.

Ah, my 98 has Alpha outdrives… I am finding that it looks like 14.25” x 17p for the best hole shot and top speed combo… and 14.25 x 19p for a slightly better top end and a better hole shot that the factory stainless 3 bladesTwin 5.0Ls with Bravo II with the 4-blade stainless 19" x 20P never felt under powered.
Hahaha well thank you for posting your original photo because it inspired me to got black. Its only half finished, he is still working on the on the glass and camper panels, but already looks way sharper in black.
