For those who own a boat, you know they are expensive to buy, operate and maintain; but the dollars spent on maintenance pales in comparison to the cost of replacing a power-head or lower unit. There are never any guarantees with these high performance motors, but I can't imagine a worse feeling than hearing a loud clunk from the motor when at WOT, and knowing it was something that might have been avoided.
