Ok, here's the story. I took my boat out everything's running fine until some dumba** jet across me and I hit the wave hard. I was only going about 15 mph. I hit the wave hard but everything was ok until I hit about 35 mph then a loud bang and the motor dies ( it didn't do this the last time I took it out). First, I thought I blew the motor but when I try to restart it, it started right back up! But it dies again as I was going at about 15 mph. It goes on and on like this the whole day. Sometimes it even died while idling. It finally quit on me when I decided to go back to the dock. I looked around and noticed the gear lube monitor was low. It was already low before I left home that day I just forgot to fill it up. I checked and noticed it was getting fuel into the carb. So I called my father-in-law to the rescue. He brought me a quart of gear lube and I filled it up. Tried restarting but unsuccessful. The guy who sold the boat to me ( 1 1/2 month ago ), told me that he had drained the old fuel and added fresh fuel into the tank. So I guess my question is, what's the next step or does anybody have this problem before and knows how to fix it? By the way, the motor cranks but no start.
