To stay with fuel injection, you can go with the Edelbrock Victor Jr EFI intake and throttle body setup. The intake is a Victor Jr machined to accept fuel injectors, rails, and sensors. The throttle body mounts just like a carb would. No reason you couldn't keep the merc computers, but it would need to be tuned to run with the new intake (any new intake for that matter).

I will go with none of the above suggestions (for now) but thank you all for your input. EFI, mild cam (to avoid reversion), liveability, and more hp is what the goal was with these 540's, and not to abuse the drives too much. The motors were just put together an Innovation, and I am not impessed with the final hp(but that is not Innovation Marine's fault); my father ordered these motors and cams (short blocks before he passed away) -- 540's with a mild compression (doesn't help make hp, but is cost effective for fuel) and a mild cam with Gil exhaust and silent choice restrict how big a cam that can be utilized to gain more hp.
I am really suprised that there is not an aftermarket plenum with bigger cfm available for this application. I am not against throwing a Dart intake and an 1150 Dominator on top, but for now it will stay an EFI boat.

Call me toll free at (866) 496-8181. I think I have a couple of EFI setups for a 540 package on rectangular port big block heads that are configured for 600HP on a MEFI ECM just like your 415/502 mercruiser engines.

Smitty and Jayhawk261,
Thank you for putting me in the right direction if a change of intake happens, at least I know what is required
