I currently have a '95 Talari 200, my second Mariah. I've used it one season, and one of the things that annoys me is that it takes a while for the engine to draw fuel when I first start it. Are there any tricks or easy ways to prime the carbs. I used to just pump the throttle on my '97, but this one I have to sit and crank for a while.
Thanks!

I have a ‘95 Barchetta 182 and when the engine is cold it takes at least 3 or 4 good cranks to get it started. It always starts and runs great but never quickly. Don’t know why, just got used to it and don’t even think about it anymore.

I assume you have a carburated 4.3LX. Generally speaking when a carburated engine takes a few seconds to start it is usually due to the fuel bowl being empty or below the proper level. In the old days you had to crank over the motor to get the mechanical fuel pump to fill the bowl. I believe your motor has an electric fuel pump. The Mercruiser fuel pump doesn't turn on until the key is turned to the start position. The pump is powered by the starter solenoid. Once the engine starts or the oil pressure is high enough an oil pressure switch keeps the fuel pump running.

So, your fuel bowl is most likely empty from sitting and the fuel evaporating through the vent. It probably takes a few seconds of cranking to excite the fuel pump and fill the bowl.

One possibility is that you may not be getting power to the fuel pump from the starter solenoid. In this case you must build enough oil pressure by cranking the engine for a few seconds before the fuel pump will turn on. To rule this out you can try disconnecting the fuel pump from the oil pressure switch. If the engine starts after cranking then you will know that you are getting power from the starter solenoid to the fuel pump. Note that the engine will die shortly after you release the key from the start position. Let us know what you find.
