    4.3L GL overheating issue

    I started up my 4.3L GL for the first time yesterday on the muffs. It started running hot. I checked the raw water impeller and it was good. I pulled the hoses of the raw water pump and turned the water on and no water is coming out of the supply hose in the bilge. I put the garden hose in...

I attached a photo. Does anybody know...

    Replaced Volvo Penta 4.3GL with Mercury reman engine - lost 3 to 5 mph off top end.

    In spring 2011, I had a Mercury remanufactured 4.3L V6 engine installed in my 20' Chaparral. It was a complete engine (minus intake and carb) that was fitted up with all the accessories from the original engine. A new intake and original carb were placed on the new engine. With the new...
