motor has not been ran for almost 4 years. i replaced the impeller, fuel pump, for rebuilt carb. boat runs good for about 10 to 15 minutes then dies out like it runs out of gas. it will crank back up and run fine. i am wondering if the motor is overheating. is there a therostat on the motor that might be bad. thanks for any info. boat also smokes real bad. I think the mixture of oil and gas is wrong.
