I'm going to test drive a boat with this motor on it, what should the rpms be up to? Is there anything I should look for? We started it up on land and water came out the weep hole, started right up and didn't smoke much. After the water coming out the weep hole became warm I noticed a little smoke coming out a square shaped hole right below the engine cover-is that normal??
