Got the engine fired up today! Sounds great on the hose at idle!!! Getting closer one tiny step at a time!! Still finishing up wiring does anyone know if there are several wires not used in the engine harness on these efi engines or are they repurposed? Like choke, magneto kill wire ect? I mean I can start it and shut it down but have a few wires that don't seem like they would go anywhere looking at a generic diagram.

Glad to see some good progress. It should run out at a fairly brisk pace. What prop are you gonna try first? 19 Mirage should be near perfect. Sounds good, post that video up...

I'll put together a better vid and post it when I get back working on it! I've got a 21p prop right now and I'm gonna try it first... Hopefully it will be pretty close otherwise I'll be saving for a new prop also. What prop were you running on this engine when it was on your boat?

I ran a 21P Thunderbolt (Mirage Copy) and a 23P Tempest with vent holes for holeshot (signature picture) When I switched from your 250 EFI to the 250 XS I lost about 3 MPH. I took a old Tempest 25P and had it customized to get my MPH back. They knocked some of the pitch out and cleaned up the edges. I think I would try what you have first. It had ought to be close. When in doubt, trim it out...
