    solid ......but solid as in multi strand wire for flexibility . copper is nice but anything metallic will work fine. 18 inches or so will get you near 0 ohms resistance compared to carbon stuff !

    1977 Evinrude 85hp - Intermittent power loss

    chat gpt opinion ... 🔧 1. Ignition System (most common on old OMCs) Stator & charge coils – These can develop heat-related failures. They may work when cold but lose output when warm, causing a weak or missing spark. Power pack (CDI unit) – Classic for intermittent misfire or total loss on one...

    do you loose it solid like and it gets back normal after a cool down period ?. have condensers (even new ones) been load tested with a proper high voltage test apparatus ?(Merc-o... or mohat box) so when did all this start happening ? after some maintenance you did or suddenly ? try an extra...

    Coils available today are dirt cheap (Amazon) & seem to have a wide range of secondary resistance values ...sometimes 4K sometimes I have seen some at 8-9 Kohms . Try to stick with OEM $$$$ 8-9Kohms may mean more turns to induce move volts or it may simply mean cheaper China...

    Visit the AOMCI western site ( link posted above) for great docs covering condensers, testing, repairs and if you plan working oldies there is a great little condenser test box you can build. You can ask mr.Mohat to send you the diagram. (read his article ). His basic model without this...

    eye testing sparks is tricky...at best at least you have sparks. suggest to read up on magnetos... never having taken out the long bolts on coils corners !! the $20 suggested for older engines explains it all as well as utubes and this article...

    1981 Johnson 115hp 4 cyl

    chat gpt says... On a 1981 Johnson 115 hp 4-cylinder (crossflow V4, 2-stroke), a sudden power loss after running fine for 20–30 minutes, then returning to normal later, usually points to an intermittent heat-related or fuel delivery issue. Here are the most common causes: 🔧 Fuel-related causes...
