I have a 1986 3270 MotorYacht that came with BB225B VolvoPenta's. I repowered with 5.7 4-bolt main long blocks. I stayed with the pre-87 version to use the original intake. My performance and economy have been going downhill the last two years. Had the carbs rebuilt and jetted, they are original Rochesters. I still have problems devoloping rpm's over 3100-3300. I don't run hard, usually around 3070 rpm would show me .80 kmpg. Now shows me only .67 kmpg and noticed continuing to give more throttle movement to achive cruise rpm. My original distributors look rusty and crusted inside but the springs are still visable, though scaly. They have pointless plates in them that I think were a retrofit, though present when I bought the boat.
I am considering replacing and wonder if the sierra 18-5494 or the Mal-9-26306 are both acceptable. The Mallory comes with a kit, new coil, wires and dist. My wires are probably 5-7 years old. Time flys when were having fun.
Any suggestions or advice would be greatly appreciated!
Thank You in Advance
