    1992 250 V8 Carb/intake/cylinder question

    How does the 8 carbs feed each of the 8 cylinders? Back a few years ago, the lowest carb on the port side was leaking from the vent so I took it apart, figuring a needle and seat, changed it and the problem was solved. I am a bit concerned because the sparkplug lowest cylinder on the starboard...

    I have a 1992 250 v8 on a 23ft Robalo CC. The engine has decent water pressure, around 15lbs at cruising speeds. At the upper end of the throttle range the water pressuer starts to bounce. I am wondering if my engine is a bit too high? Also, on acceleration or cruising in choppy water, the...

    I have a 1992 250 v8 and this year it appears to be loading up at idle. It will run fun at idle then I'll notice the idle will drop off a bit.

    Evinrude 250 V8 starting question

    I have a 1992 250 V8 outboard........Whenever it sits too long, like over the winter, its a b_ _ch to get started. Once I get it running once, its usually not a problem. I suspect that I should look into my fuel system and priming pump....Any suggestions would be great..... Thanks, Justin

    1992 250 V-8 question about carb prob.

    I have a 1992 V-8 evinrude and am having a carb problem. The engine runs great but dribbles fuel from the air box at low speeds and idle. As it turns out its coming from the vent on the lowest port side carburetor. I assume its the vent, its a port in the bowl just below the gasket. I was...

    L/U input shaft endplay 1992 250 V-8

    When I did my water pump a couple of weeks back I noticed the input shaft (from crank through w/p) can rock around a bit. There is no side to side movement. In otherwords, once engaged in the crank it cannot move. Is this normal? At first I chaulked it up as normal so it aligns with the crank...

    1992 evinrude 250 V-8 cooling question

    When I first ran the engine on the hose, the **** stream was a little weak. Figuring it'll get better once in the water, I tried it but not really any better. So I did the WP and tested it again. The stream is better but not great (at least as compared to my Yamaha). Its not overheating but it...

    Using the tach lead to power fuel gauge question

    As I see it, the three wires for my tach, grey, purple and black, I should be able to branch off of one of theose wires to power my fuel gauge when the key is on correct? Which one? Or should I tap into my key switch wiring? I figured the tach harness is right there so it'd be easier.

    How do I know I have the shift cable adjusted properly?

    I rigged a new BRP binnacle control box last night on my 1992 250 V-8. After setting it up I noticed the shift cable at the engine, never returned to the exact same spot when shifting from reverse to neutral and forward to neutral. Once I started playing with the control box I found the throttle...
