Twin 150’s or single 300?

[williamscott]

The doubled-mechanic-labor point is the part people underestimate. Two 150s share the same service interval, so you're paying labor twice per season, and the second set of anodes, filters, and gear lube adds up. The $161 kit figure is helpful, but the same kit for a pair runs close to double, plus plugs and impellers on a second lower unit. For the single 300/350, one oil change, one water pump, and one set of plugs keep it simpler. On docking, I'd weigh how often wind and current line up against your slip before deciding.
