The Motor won't start??

I've seen these V-6 loopers idle at 2000, and then drop down to a 600 idle in the water. Back pressure is VERY crucial on a looper. Loopers flow more efficiently up high, and tend to produce more high rpm HP, whereas cross-flows pull extremely good down low. This is why many people were dissapointed with loopers when they first came out. There boats would rocket on plane with the C.F. engine but fall off up high, the loopers would struggle to get on plane but once they got on top would fly up high. This is why most small HP engines are C.F.'s. Don't pass judgement on the engine until you get it in the water.
