Hi have a 350 in my 93 renken and it cranks but no start. I checked a few things and it seems to have real weak spark, can anybody steer me in the right direction on what to check.

it has a electronic box that sits over where the distributor would be and some kind of electronic distributor.

I am thinking that there is a pickup in there and that might the problem but screws are rusted and want some input before o break them and have to drill them out.

Thank for any help you can provide.
fuel is good

there is no readable markings on the box, but i believe it has Yamaha controls if that helps. its a large flat box wires out both side to separate coils l&r power and signal from the dist thing. I will check again for any numbers or names

Might want to post a picture, from the sounds of it, you may have a Yamaha YEMS system.
May look something like this.
