    Default transom headers

    Hey guys looking to fab up some headers to replace my logs and snails. The header fab is pretty easy and straight forward. The water cooling part is what input I'm looking for. What is the best way to plumb in engine cooling and header cooling now that the logs would be gone?? Its a jet and thru transom exit as well. Thanks.

    Marcsrollin on this site had a set of through transom with a T valve....the ball/spring got sand in it and didnt allow water to the headers. The exhaust hose melted and he was forced to run his boat right up on the launch ramp to keep from goin down.

    Ya prob was water injected not jacketed? Not too hard for me to fab water jacketed style tube header. Tube
    within a tube. When I used to make alcohol or fuel headers this is how they are made. They obviously dont have water in it but not too hard to redesign to allow for water. Question is what is best way to cool motor? If water comes straight into motor first without preheating , is this bad? Run way too cold??

    NO just run a valve to adjust water flow.
