With a 25 HP do not go more than 75 amp. Too much lost for that HP.

I had the original Yanmar 3GMD. The problem was leaking oil from the intake manifold caused by serious blow back. There is also a transmission problem, where it doesn't always go into gear. So the decision has been made to put a new engine in, and as someone mentioned over capitalize the boat. But we sail to the outside of Vancouver Island and up north to where engine problems would be a super pain. (Soon I will post information about the engine and extra parts in case anyone is interested. It has an almost brand new exhaust riser on it built by Gartside.) The old engine is out and we are now sound insulating the engine compartment. The boat currently has an ice box but putting in refrigeration is high on the list. Getting ice rapidly becomes a challenge as you head off. This would imply more battery power and an alternator to keep it going. We are looking at a Beta 25 for which you can get a 75 or 120 amp alternator. Because of limited battery space I'm thinking of using AGM batteries which you can suck more amps out of. Has anyone got some words of wisdom and/or experience with this? Including what is the minimum amount of available amp hours you need? The water is cold up here and it usually doesn't get too hot. It seems with AGM batteries you need a fair bit more charging capability. Although the refrigeration project is a little further off I don't want to but too small of an alternator now. Thanks Don Jonsson Victoria, B.C. _______________________________________________ The bills have started coming in for the year 2018 and have gone up again. October will be our fund raising month.
