Hey guys,
Received my plans from AMA on a potential addition to my hanger. Plans call for a 0.15 O.S. Max with a low profile Tatone manifold mounted inverted and fully enclosed in a cowl.

Not familiar with this size of engine, do you guys have any recommendations for this or a different engine? Plans are from about '84 so I'm sure there are a few new choices in engines. Being a seaplane I could appreciate all the power for weight and don't mind stepping up to a .20 if the weight is comparable.

Thanks for your thoughts.
