    By taking timing out i mean it goes from 14⁰ to 9⁰ advance. Then at higher rpm goes from 22-24⁰ to 18⁰. I did try removing the shift interupt switch and it didnt seem to change anything. My points distributor springs are shot so after i come off plane it stays advanced and will not do...

    Hard plane after switch from points ignition

    Set total timing. water tested the boat. distributor is actually taking timing out at 1500rpm. get full timing at 2500rpm and anything above it takes timing out again. time time to ditch the delco est and go back to points if i can get my points distributor rebuilt.

    Hard plane after switch from points ignition

    Im not 💯 sure what the timing is at 1500 rpm. But at 2400+. Its 18⁰. 10⁰+ 8⁰ advance. I think my issue is that its not going into base timing mode. So when i set my initial timing, im already advanced half way into the curve.

    Hard plane after switch from points ignition

    Today i swapped out the module for an Ac delco module. Now i get 15⁰ total timing. 10⁰ base plus 5⁰ advance. At this point i am at a complete loss. Getting ready to ditch the sierra EST and find something different.

    Hard plane after switch from points ignition

    Hard plane after switch from points ignition

    1985 mercruiser 4.3L engine. Engine is in a 1985 arrow glass carisma 188. Boat originally had a 3.8L mercruiser. Boat ran fine but the points distributor was at the end of its life. The mechanical advance was seizing and springs were shot. Advance would get stuck. Skip forward to this...
