I’ve seen that ad and would like to know more about it too.

Id guess close to 90 depending hull weight.

And s blast to drive 😉

I talked to the owner. He has twin 400's and it runs 90 which is pretty much what I run in a slightly smaller Velocity with my 700hp I/O. Based on our conversation it handles the same as mine so no benefit there. He did say fuel economy was real good about 12gph at 45. I get about 2.5mpg at 50-55 so pretty much the same there too. All in all it's a toss up, I build my own stuff so cheaper for me to go with an I/O for sure, and I have a lifetime warranty. LOL

They are building a new 280 with the new twin 300's that should be interesting. I think its in rigging now.
