I bought a boat with a 440 in it, put it in the water and it felt sluggish. I can't find my dial back light so I checked it with a std light and it had 5* after. I gave it 17* more to 12* before, runs much better but it feels like it could use a bit more. I'd like to run 35*-38* total and need to know how much mech adv is built into 3690432. This is the dist that comes in the MP conversion kits.
