I need to replace a 25 hp merc outboard on an old aluminum boat. We use the boat mainly for river fishing. The motor has seen it's share of stumps, rocks, and steep concrete ramps (ouch). It's just isn't reliable anymore and needs another rebuild. I would prefer not another mercury. Any thoughts on what manufacturer I should consider? This is a co-owned boat, but I'm the only one frustrated enough to put up $ for the motor. So, less expensive is better. Maybe Nissan, Tohatsu? Or bite the bullet for a honda? Any advice is appreciated.
