I'm looking to repower a 91 Outrage 22. Because the boat is already rigged merc, I'm planning to stay merc.

My question is this - what are the practical differences between the EFI and Optimax series motors? Fuel economy, noise, maintenance, etc? I've only seen list prices, how much difference is there in "street" cost between like HP Opti vs. EFI.

Also, the 200 through 250 EFIs and the 200 - 225 Optimax all appear to be built on the same 3.0L block. Within the families is there any reason not to get the bigest HP - what is the difference between the 225 EFI and the 250 EFI (or between the different Optis)? Is it just how they are tuned. Or just that one has a higher WOT rating. If I'm cruising at 4000 rpm, is there going to be any noticable difference?

Finally - I live on the great lakes and can't imagine moving to either coast. Is ther any reason to get a saltwater version?

Just quickly, assuming you are talking single power, you will HAVE to get a Saltwater model. It means 25" shaft.

The 200 EFI is not the 3.0 liter block. It is 2.5 liter.
Opti's get better fuel mileage, are clean, weigh more, cost more, are noiser at cruising speed, produce no smoke, require expensive plugs and oil, and not quite as fast. EFI's are also bulletproof in reliability, but smoke on startup and idle, and sound powerful. In EFI, the 225 is your best buy. The 250 would only give you one or two MPH additional top end. If you want all out power and speed, get the 250XS Optimax from the performance division. Nothing else, any brand, touches it @ 250 HP.

I would get the 225 EFI. See Louie Kokinis's 22 Guardian in Cetacea. You have to decide which of the above qualities make the most sense to you.

Thanks for the info - intersting that the freshwater 200 EFI is 3.0L, but the Saltwater 200 EFI is 2.5L

Dave -

I just replaced a 1989 Johnson 225 with a 2003 Merc 225 Optimax on my 1990 Revenge 22 WT (Cetacea 44), have 11 hours on it. Right off the bat, lhg is accurate. Fuel economy - 1989 Johnsoon carburated 225 got about 2 mpg at BEST. Just goofing and cruising, the Optimax is getting at least 2.8 mpg. No smoke on startup while the old Johnson had people threatening to call the EPA. Noise - I don't notice much difference. Maintenance - I did all my Johnson work, will have to see about the Opti. Top speed is about 2 knots faster (a touch over 41 knots by GPS). Cruising at 4000 RPM is about 1.5 knots faster with the Opti than the Johnson.

"Smartcraft" instrument package is interesting, but a lot of pushing of the "Mode" button to see different funtions. Got to look at it when you push the button - means you're not looking at where you're going. You can outfit with analog instruments.

I talked to Louie about EFI vs Opti, and I wanted a bit newer technology so I got the DFI.

I'm satisfied with the 2003 Opti 225. $13,800 installed with 2 props - aluminum and stainless Revolution 4 (4 blade).
