Has any one dealt with these folks? I was told that they have been rebuilding marine motors for 30+ years. Claim to have less than 3% return rate on their rebuilds (that's good, isn't it?).<br /><br />I've got one on order, just wanted to check them out more.<br /><br />Also, can you tell a GM 305 from a 350 by outward appearences??<br /><br />thanks, Larry
