stan,

did you have to adapt your fuel lines or did they stretch?

More spacer isn't necessarily a good thing. I'd go with cstraub's recommendation.

Personally I won't change anything on my intake system on a boat motor unless I'm doing it on a dyno. You never know what changes are a plus and which ones call for a jetting change.

You may want to contact cfm-tech as he has made many pulls with various combinations and can tell you what to look for.

What about the thermal barrier properties of the phenolic material? Is the transfer of heat in a marine engine compartment not as much of an issue as in automotive? I have used a 1" Mr. Gasket phenolic spacer for many years and thought that the thermal barrier it provided between the intake and carb was probably as much of a gain as the extra air flow and signal it may have provided. I realize and fully agree that they are mainly a tuning tool but what about the heat?? I plan to purchase a new tapered/blended spacer but am still unsure as to which direction to go.....Canton, HVH ,Wilson and others. Any comments? Please!!
