Preped motor in spring on muffs and ran fine. Launched boat wouldn't run. Back on muffs ran fine. Launched again wouldn't run. Took off hood at dock motor started right up, replaced hood-motor died. Again, hood off ran great, hood on died. Found- after much head scratching was 4 of the 6 bolts holding lower unit to power head were missing. Replaced bolts and motor runs great.
