I had just recently purchased this motor and I was at the lake yesterday driving around and the previous owner neglected to mention to mix my oil and gas. All the other boats i've owned have been oil injected and you didn't have to mix the oil with the gas. Well i ran down the lake for a while and all of a sudden the boat just bogged down and quit, since I was unfamiliar with the new motor i didn't even try to start it more than just to make sure it would still start. I've been told it could've done a lot of bad things to the motor but i put oil in with the gas and the motor began to act better, it idled better but when I would try to blast off it would bog down again and i couldn't get on plane so i gave up, hoping that i didn't throw a rod or ruin my heads or anything. If anyone has some insight on my problem please let me know. It will be much appreciated.
