Re: 1957 35hp Johnson Generator Question

[WAYNE]

I agree, Richard. Generators are seldom necessary for most outboard powered boats. However, I think its better to have a charging system than not. I have the alternator option on my 1955 Mercury MK55. It keeps the battery fully charged all season so I never need to pull it out for charging. The battery is used for my navigation lights (which I frequently use) and for the fish finder I used all last week while on vacation.

I’m also planning to use two 40 hp Johnsons with generators on a small cabin cruiser that I’m restoring. The generators output full amps at approx. 2000 rpm, which is well below cruising rpm. Charging is important for maintaining the batteries while running the chartplotter, VHF radio, lights and 12V ports. I plan to spend entire weekends on the boat so my situation is not normal.

Solar panels work great for charging, but I like things to look period correct as much as possible. Its hard to hide a solar panel.
