Guys,I have a comp viking with 2.4 offshore and jackplate.I have always ran a twin pinion speedmaster lower.This year I am going to a shifter lower, with bobs nose kit, and a tork tamer tab.I have a blowout ring to put on this unit.My question, is it needed, will it be faster or slower or just doesent matter?.I will be running a 28 offshore cut and a 28 cleaver.The unit is stripped for paint and now would be the time to install it.
