Exhaust
Plan the exhaust carefully. It can be a major
source of trouble if not done correctly.
We use a 3 inch offset 90 degree header and
tuned pipe.
Be sure that your pipe is mounted firmly near
the outlet.
Never pull a pipe to one side to mount it. Even if
you only put a little side pressure on the pipe
when mounting, it can leak water into the pipe
and kill performance.
We like to assemble the header and pipe to the
correct length (13.5 inches for the Zipp Super
Tuned Pipe) first.
If the tip of the pipe is short of the transom, use
an exhaust outlet and silicone tube.
If the tip must pass thru the transom, either
loosen the pipe and slide it forward on the
header, or remove the engine mount bolts.
You need to be able to slide the engine back so
that the pipe tip just contacts the transom.
Be careful not to pull the pipe to either side.
Carefully mark around the tip, on the transom.
Drill this out in steps so that the tip will fit the
hole with a piece of silicone tubing over the tip.
Use Zipp hi temp silicone exhaust tubing to line
the hole in the transom.
Pipe against transom for marking.
Transom marked for pipe.
Note silicone surrounding pipe thru hole.
