I recently overheated my 1991 Yamaha 150 V6. After changing the water pump I found that now I cant get up on plane. I idle ok and start out ok but it just doesnt have the power to get up and it seems to bog as if i was pulling a really big load. Sometimes after a really long time I might get on plane. I did a comp test and all 6 cyl are around 105. Someone said i may have burnt out my high speed coil. Any suggestions!
