Loopers versus crossflows

[rumrunner]

I believe loopers are much better engines than crossflows.

I like the one's that start when I turn the key or pull the cord... max 3 pulls.

But I'm sure there's more of a debate out there.

Was my 1978 9.9 evinrude a crossflow or looper?  That son of a gun started on the second pull for 20 years.

I believe that was a crossflow but can't say for sure. You have a very valid point. Reliability really should be above all else for a fishing moter. I've had several of these old omc's that did great for a long time. But when things started going it was one thing after another. The crossflows versus Looper really comes into play on the bassboats. Do the crossflows make their power at lower rpm? Do the loopers make more power but at higher rpm and does that help top end? Does it matter to anyone but hot Rodders and tournament fisherman?

Much better at what?  There are advantages to both designs.  Stronger idle, smoother stronger acceleration, and dependable hole shot with a crossflow. 

Better fuel economy at WOT and quicker acceleration once your out of the hole with a loop charged design....but with an increased likelihood of detonation and/or meltdown.

has absolutely nothing to do with the induction design of the powerhead.

That comment wasn't directed at just crossflows. My experience with old outboards in general. I'm going thru the fuel system on my '93 50hp now. But the starting and ignition have been perfect. More than I could expect for its age.
