1988 Johnson 140s VRO and plug advice

[usmma2013]

Thank you for the plug recommendation! The motors have NGK plugs at the moment, I will replace with the Champions.

I'm definitely going to keep the VRO. 1988 was the VRO2 system which is very reliable - I was just interested to hear what/if any p.m. on the systems would be beneficial, should I replace lines or bulb, flush, etc.

Heres a good article on the VRO systems!
