Just for the record - The 4 stroke Nissan 6HP is the exact same engine as the Nissan 4HP. The only difference is the carb. You can buy a 6HP carb for a 4HP Nissan and turn it into a 6HP. You may get a little better thrust with a different prop but I'm not sure about that aspect. I can't understand why they charge so much more for the 6HP since they both have to have a carb and I know for a fact that the 6HP carb is only a few dollars more than the 4HP (maybe even the same price $100 plus or minus for a brand new one.)
Same scam Briggs & Stratton was pushing a few years ago. It was known in the industry as "decal horsepower". What they did was to measure the HP at a higher RPM in order to show the higher HP. unfortunately, in order to keep it in one piece, you didn't want to actually
run the engine at the higher speeds. Uncle Sam squashed that one, and is why you now only see cubic inch displacement figures on their engines instead of HP.
As far as why manufactures offer multiple HP of the same basic engine, that's because consumers want what they want, and the factories are anxious to oblige. why the cost difference? thats an easy one.... because they can. easily justified because, after all, it has more HP so it
must be worth more money :roll eyes: . the cost to produce a product has nothing to do with how much it sells for. hasn't for many many years. ALL products sell at whatever price the market will bear. if it turns out to cost more than that to produce, production simply stops. which explains why so many "great products" go off the market unexpectedly.
And now you know, the
rest of the story.
