I'm new to 3.5 outboard tunnel hulls, and need a little help. I have 3 K&B's. Two of them are brand new 1 is used. I have not run the new ones yet, because I'm not sure about how hot to let it et during break in. I've read the FAQ's and they are a little spotty. How warm is warm? How long do you run it at that temp?. They also say to run it rich. Running it rich want let the engine warm up. Also running the engine rich can snap the connecting rod.
On my used engine after a full tank run you can touch the head with no problem? Is this ok. All the engines are water cooled. Any advice on these topics would be great thanks.
I have a IR heat gun, so temps would be the best.
