Looking to purchase boat with 2000 150 h.p. 2 stroke johnson ocean pro with a apparent electrical issue,doesnt turn over, Im considering the sale because of price. Anyhistorical glitches,lemon aspects, about engine or electrical system that could be considered before starting specific troubleshooting.Turn key, alarm beeps , slight click thats it. Battery and connections all good.Any advice would be appreciated. Thankyou Andy
