Re: Mercruiser 165 IL 6 electronic conversion kit
I have installed electronic conversion kits (incl new coils) on a pair of OMC 165s. The idle has newer been better. With the old points, they shouldn't get below 700-800 rpm, otherwise it felt like they could stall at any time. (new points will off course had helped here) But now they run like an electric motor and can go down to 500 rpm.
Throughout the rpm range, the engine runs more smooth, I think.
The kits came from "hot-spark". They are very easy to install, no external box, it is all hidden in the distributor. Two wires, adjust timing, and you are ready to go.
Off course, well adjusted new points makes an engine run great, but I believe that system is outdated.
Electronic ignition newer wear out and requires no manitainance, great.
