Hi all! i recently purchased a 1967 6hp Johnson for a small jonboat. The motor overheated the first time out and I shut it down quickly. Noticed no water coming out exhaust ( ne pee hole). I pulled LU and found impeller seperation so i replaced entire water pump. No she pumps out the exhaust hole at all times but still overheats after 2-3minutes at WOT. Idles ok for quite a while. Once the motor colls its starts right back up. Any help would be appreciated.
Thanks
Thanks
