It also looks like the 15 and 20 HP are the same weight and displacement.
15HP
4500-5500 rpm range
15HP@5000rpm

20HP
5000-6000 rpm range
20HP@5500rpm

Carb looks like the culprit here also.

It is my understanding that the camshafts are different as well.

They probably are different. The RPM ranges are different so the cam you think would be. This is not on the spec sheet at Honda Marine though.

They don't want you to know all that stuff.

They want to sell HP.

If the motors are essentially the same then get the smaller one.
It will work less and last longer.

Actually the reverse is true, the more horsepower the motor has the less it will have to do to move the same boat the same speed. The more HP motor will be using less of its reserve capacity.

I disagree.

All the bearing surfaces and working parts will be under less strain all the time.

I have the 8HP. It's heavy, quiet, a one pull start. Aside from the ethanol issue... and that you MUSTY add fuel stabilizer.. it's a good clean motor.

The weight is a pain so I got a demountable Garhauer crane.

How do you like that crane? I have a Garhauer davit and find the construction to be very good.

No, because the motor will be working harder to do the same thing, like more rpm to get the same speed. Anyway who cares? This was supposed to be what are the differances and I showed the differances.
