Well i bought the boat a year ago and my fault for not researching alot more then i did, but it had a 455 olds from a mid 70s car. It ran ok...had a stock manifold with a quadrajet on it which didnt have working secondary's. I put a new carb, manifold, bigger oil pan and the drain back from the heads...well i spun a bearing over the 4th.(thats my other problem) I just wanted to find out...before i mess with the pump if it has the wrong size impeller on it.
