My son bought this engine used. It had been sitting 2 years. We installed it on the boat. It took a little effort to crank but once running ran fine. Put it in the lake cranked right up let it run for about a minute. Eased into the throttle and it smoked more than normal for about 5 seconds. Putted around for a minute then gave it abut 3/4 throttle jumped on plane ran perfect for 30 seconds then lost 3/4 of the power. Clean carbs,new fuel pump,filter and new fuel connect to engine. Had to use starter fluid to get it cranked. Then no problem. Ran it for 15 minutes with the ear muffs. Put it in the water ran it for a minutes. Eased on the throttle and it would only run about 1/8 throttle wouldn't take the fuel then it cut offl. Couldn't get it to crank back up in the water. Any ideas. I have spark to all the plugs.
I already installed a new water pump. Aren't getting any alarms. Haven't checked compression yet. That's next on my list.
