Have 225 Promax 2.5 Litre with Alien cowls. Boat had Year 20002.5 Litre 200 with Standard Cowls.
Presently one "larger size" Rigging tubes go from transom to motor for each motor
1-Is their an adaptor (coupling) that goes from larger rigging hose to smaller rigging hose?
2-Can I get all rigging (fuel, Harness, battery cables, shift & throttle cables, etc., no oil lines) through one smaller rigging hose?

3-Should I just Alien double rigging outlets?

Hope this makes sense
Thanks, Mike
