"i just got this engine and it
"i just got this engine and it starts and runs good out of the water. i did my compression check and it checked out fine. but i have 2 problems with this boat. #1 it idles fine the water and when i put it into foward and im trimmed all the way dow i will fill and hear a thump thump thump as if it is slipping in and out of gear. its not a grinding sound like when you first put it into gear this sound is when you start to increase speed, it will quite after several thumps. then my boat will plain out and it is fast. now #2 problem it will run fine for about a minute and suddenly loose power and come off of plane. the carbs are rebuilt and i do have new plugs and plug wires ordered, but i dont think that will fix it because ive took this boat out serveral times and on first start up in runs fine. do you think that i could loose fire through my plugs or plug wires after a minute of operation serveral times without any missing or backfireing during that first minute of operation. i can twist the distributer and increase my speed to just plain out but thats it. thank you if you have any suggestions"
