1345Re:: Battery charging.
- Feb 5, 2017> As I need to get a new outboard, I thought I'd get one with a coil to charge the battery. The extra cost is minimal, if anything.However, it seems that the advertised wattage output is only achieved at or near maximum revs.> I may still go for a coil version outboard for backup but a pair of modern solar panels looks likely to be more effective.If you need to buy a new outboard anyway both decisions are eminently sensible.But I think there is a bigger issue with the outboard. Most outboards are designed to drive lightweight planing boats at planing speeds, rather that punching displacement boats through a seaway. They will do it, of course, but not as well as one designed for the job.Other things being equal, if I were buying again I would be looking for one with a "saildrive" gearbox and propeller; i.e. a large diameter prop, and either with a much finer pitch or a bigger reduction gearing.My 5 h.p. Honda has served me well, but even with the fine pitch option (and there is a choice of only two props for this engine) it is still over-propped; the engine sounds as though it is labouring slightly and is unable to achieve the revs that I would expect, and the boat is more seriously impeded by strong headwinds or by head seas than I would expect. It is not a major issue, but it is a detail worth thinking about when buying a new engine.Oliver
