As I read I chuckle a little... Doesn't anyone really know? Some are one the right track, like added R&d cost, it's a hobby or luxury... But have you ever looked at the parts inside a marine engine? Have you ever wondered why the old 2 strokes lasted so long? The engines are built better. Car/truck engines use a sleeve type bearing, but marine or at least the old ones used all roller bearings. There's is quite a large price difference in the base cost of the the bearings as well and the set machine set up for the rod caps and journals. And as long as those old bears get oil and don't over heat they are going to last! They were made with all good quality chrome. You will also notice they are sitting in water all the time so everything has to corrosion resist, and they try to use metals that will resist electrolysis due to metals alkalids or calcum in the water. All this goes into R&d as they try to make sure they build a tuff engine that hold up,the crappy fuel regulations the EPA keeps pushing with ethonal, in with a gas engine is not designed to run with added maintance... theres a reasone race cars use it and street cars don't!
Making engines lighter, also means using a alloy that is stronger, a and that means trying to match metals that have similar expansion and contraction rates so you don't have issues with gaskets blowing and bolts pulling threads like some of the auto makers have with there great ideas!
All this adds up, and yes add that to a luxury and you get $$$$.$$ X2!
No hobby is cheap, if you do find one let me know cuz I sure would like to know how keep my wife off my back! Lol
