We recently had our 2006 Bayliner BR225 engine swapped after what we believe was an impellar issue at WOT resulting in rod or crank knock. We swapped out the long block 5.0 with a reman 5.7L carb and the tech swapped all items to the new long block. After swapping there were a myriad of issues involving proper cooling and it was finally found that there were parts of impellars lodged in the cooling system.
We took the boat out for the first time after getting it back and it was having issues staying running and finally would not start at all and we had to be towed in. The plugs were fouled badly and my tech swapped them out. It seems that there are still issues which cause the boat to run at 175 to 200 on the hose even after replacing the impellar and housing, manifold and riser gaskets, all sensors, distributor, 160 thermostat, and some other minor parts.
Now the tech says that the 2 barrel OEM carb and/or the flame arrestor may be causing the engine to not get enough air and is leading to over fueling. The flame arrestor does seem small to me, but I am have searched for two days trying to find a larger arrestor and new 2 barrel carb. I am attaching pictures of my current carb and arrestor.
