Oh, as an added note... This motor has a CDI PowerPac on it.. and it works great... only problem is that this particular model powerpac (113-6212) that's on the engine calls for the engine to be a 1993 or newer unit. Not a 1991. So now I don't know what the hell I have. (I'm pretty sure it's an outboard motor) The I.D. quest continues......<sigh> |

$209 about right for a set of carbon reeds for the engine? :head:

Thanks for the link.. I'll give them a shot. BTY, based upon the cowl I've narrowed the engine down to: 200TX, 200CX, 225T, 225P.
Which brings me to an interesting question. If the engine is a 200, and it's got 225 carbs on it, does that change the HP of the engine? Specifically, what I'm thinking is that since the venturi of the 225 carbs is wider than the 200 carbs the airflow thru the venturi is going to be less. What I mean is that if the engine is in fact a 200 then it will require x amount of air to run. By making the venturi larger with the 225 carbs the engine will draw the same amount of air in, (because that's controlled by the engine's displacement), but the air velocity through the venturi area will be different, due to the larger opening. The engine will be able to breath easier, which may be a good thing, but will the engine still have enough vacuum to properly break up the fuel from the main jet as it enters the air stream in the venturi? Damn, my head is swimming now... <sigh> You shouldn't do this to an engineer... it's bad for our sanity....:devil: |
The ONLY difference between a 200 and 225 IS the carbs, that's it. If you run the smaller carbs it's a 200 and the medium carbs is a 225(large carbs were only used on early HO style engines). And as far as powerheads go, from 86 to about 93 they easily interchanged with each other. And even the late model powerheads can be swapped in if you have the correct driveshaft for the crankshaft in the engine. So who knows exactly what engine you have. That's the thing with the OMC's, there was a HUGE parts interchangeability with them.

Well, that explains things... I'm thinking that it was a 200 rebuild and then they bumped it up to a 225 for that last oz of thrust... I am sooooo tempted to pull the engine and put my 200 Merc on.. that's a $0 conversion.. just time and maybe some bolts and stuff... Still, I think I'm going to fix this engine, even though fixing it is keeping me from fishing <sigh>...
decisions.. decisions :head: |
Ok.. New (used) carbs are on order. Found a really nice set of 200 carbs (2 screw butterfly plates) off a 1990 200hp Johnson. Made an offer, got all 6 at a really good price.. complete set, bodies, bowls, throttle plates and linkage. Should have it before next weekend.

heck i have 3 sets of the 200 carbs on the shelf thought you were looking for the same 225 carbs.
