So I have a new to me boat with 360 hrs on the original motor. The seller advised me of a weird startup issue with it, but played it off as normal.

Here's the issue (if it really is one): Both the main cluster switch AND the Acc switch on the dash must be activated to start. Additionally, the spark plugs don't fire unless the key is no longer turned all the way to the start position. In other words, I have to turn the key and the starter turns the motor. I then have to kinda time when I let off the key for the ignition to actually fire. I suspect some wonky wiring repair has occurred sometime in the past.

I should point out that the motor is definitely difficult to start when cold despite me being very familiar with carburetor engines.
