Evinrude 200xp Service Manual
87 vs 89 The Cube are different as stated. Also the porting is different. I am sure that there are a few folks that can talk to porting differences. I may be wrong, but I think the 87 has bridge ports that did not carry over to the 88/89 motor.
Sometime in there they introduced some finger porting. Carbs are different too. Can't remember on the control box. 200 vs 225 (88/89 model year) Not much.
If you look in the parts book and service manuals, the carb bores are the same and the high speed jets. I think the carb part numbers, idle and mid jets are different indicating that maybe the mid-range is a little different. I think the control box are the same, so I would say that they are the same in max output. Now for the 2000 200 vs 225 vs 250 The 225 has the same parts as the 250 and the 200 has different parts (Carbs) as well as smaller high speed jets. What I have observed: For a given year, most changes seem to be in the carbs and jets. Ok Here we go. 86-7 2.7 litre Early 86 had the big carbs, difference between 200xp and 225 similar build time.
No baffel in air box on the 200 and.675 depth head compared to.700 yes the 200xp had more power. XP Performance mounts. Both are bridge port exhaust 88-92 3.0 oval exhaust port 200xp/225 same other than color xp had performance mounts. Both had baffel in air box 93 intro closed deck 3.0 with finger ports, smaller and lower oval exhaust port.
The LE version 200 same as the 225 standard 200 had smaller carbs. They remained basically the same for several years, some carb design changes, intake changes, 94 small head change. Over the years ignition did change, most notably the intro of quick start in 88 with a single power pack.
Lower units also changed slightly. 92 started a new trim system. I have basically put together an engine using what I feel are the best stock parts I had on hand from different year models.
I have carbs with 3 different throat sizes and about and every one of them was jetted differently from the factory(idle and intermediate). The big throat set I used had 77D high speeds, 39 intermediates, and 36 idles. I used a set of the angled intakes instead of the 90 degree bend intakes. I have a 93 model fingerported block and a set of the 2.7L heads.
There was also a change in the weight of the connecting rods. The find a big difference in the weight of the connecting rods when I started tearing down some blwn powerheads, but I am not exactly sure what year this changed. I did put a set of the lighter rods in my engine. I do have a few spare blocks including a 2.7L block and a few pre-93 3.0L blocks I have been wanting to put together one of each just to play with, but that is more money than I'm willing to soend right now.
Is there any problems that yall can think of with running the twin powerpack setup? Any suggestions for further mods that are easy, possible with stock parts or can be bolted on at a relatively low cost. I think the big Johnrude looper is interesting in the respect that there are a lot of options available to boaters who want to build more power just by using stock parts from the different year models. There are some pretty good power gains that can be made with these engines. I knew Alan would jump in there. He know more than all of us put together. And I knew he could not resist a OMC V6 discussion.

Given all that info, is there a year that stands out as better or best for Hot-Rodding? Any particular years porting set up the best?

Does the Last of the Carbed OMC's (the 225 HO) represent the best it ever got, or are some of the older ones actually a better set up? Alan, your infinite wisdom please! PS - Really miss you guys racing in Minneapolis on the Mississippi.

I've been depressed ever since they dropped this event from the Aquatenial celebration. Where is the closest place to Minneapolis I could go and see some racing? Last edited by BuickTurboSix; at 10:28 AM.
