40hp Mariner Question

[andreworiordan]

Hi Guys,
Im thinking of getting my 40hp X-RNLI fitted with an alternator (rectofier) to charge my batteries and run all my lights, The engine itself is a Mariner 2004 model. What do you think I would expect to pay to get this done? would like to know so I don't get such a fright when I get handed that bill.

I'm thinking of fitting a Zodiac A-Frame to my boat and adding nav lights and a few spotlights, Hoping to take the boat out of the water in the next few weeks.

It may already have an alternator on it. Do you mean you only need a rectifier?
