I have a 1980 Hunter 33 with a 2QM15 Yanmar engine. I need to rebuild the engine or replace it with something new. Yanmar now makes the 2GM20 with 18 HP and the 3GM30 with 27 HP. The 2GM20 has more HP than the original engine but less torque. The new engines are smaller and probably will have different mounting requirements. The original engine was a bit under powered in my opinion. Any information would be helpful.
