Help! What brand engine should I buy?
i repowered my 30 ft boat with a Yanmar 3GM30F about 15 years ago and I just love it. It starts instantly always, is very quiet, burns only about 2 qts per hour, and is extremely well built. I would recommend it or the other GM series (1GM10, or 2GM20) engines. The only thing to watch out for, and it is true of any engine used in sea waters is to religiously change out the heat riser every 4 years without fail.
