Outboard will only start when given 10%-30% throttle. Will not start when given full throttle or half throttle.

Yes . Hard to diagnose. Still gave great compression.

Also, did you buy Crosbyman a beer? At least give him an "atta-boy"!

I will buy Crosbyman (the winner ) as many beers as he can drink !

So what was actually wrong?

The head bolts needed tightening. That's all. I'm no expert, but I think most hard starting 96+ 99's and 15s can be solved by removing the lower cowling and tightening the head bolts. I also feel the 93-95's are more robust ( my favorite years for that block )

Wait a minute, Cros said leaking crankcase, and you tightened the head bolts???

This is weird.
