Mechanical & technical differences between new Merc 4-stroke 60hp and 75hp

[MGood777]

I am looking for some technical detail about the differences between 60hp and 75hp 4-stroke outboards. Does the 75hp makes use of more advanced ignition, fuel delivery, electronics, etc. Wanting to know what the extra $1100 might buy me besides just another 15hp and 120 pounds. The Mercury Marine site and product literature has very few details. Can anybody share or link to some detailed information or comparisons? Thanks in advance for any help.

If this link works, the differences are clear. https://www.mercurymarine.com/en/us/engines/outboard/compare/?e[]=301&e[]=302

Thanks for the reply. I appreciate the link and I have seen that comparison, but I disagree that the differences are clear. Take a look at the fuel induction system on the 60hp. It says SOHC and 2 valves per cylinder. That's got nothing to do with the type of EFI that's used. It may or may not be the same multi-port EFI as is on the 75hp. Same could be said for ignition. Is ECM 70 the same as "SmartCraft" ECM 70 Inducive? As far as I can tell, you can't know whether all those systems are different or are they the same and the marketing people just happen to be more descriptive in the 75hp descriptors.

Please!

The 60 is 995 cc and the 75 is 2.1L or more twice the displacement.
The 60 has 18A alternator and the 75 has a 35A.
The 60 has power trim and the 75 has power tilt and trim.
The gearcase ratios are different. 60 is 1.83:1 and the 75 is 2.07:1
Both are fuel injected.
The 75 has a higher price and is 100 lbs. heavier

Where is the fuzzy marketing?

as GA stated, where is the fuzzy marketing. its like buying a truck. one is a Chevrolet Colorado, one is a Chevrolet Silverado....one is bigger than the other, costs a bit more than the smaller one and weights a bit more than the smaller one.

Apparently the 60 is the largest of that block size, the 75 is the smallest of the next up block size.

Kinda like how the Optimax 75, 90, 115, 125 are all 1.5L, then the 135 all the way up to 225 (I think...maybe 250?) are the 2.5L

Now having said that, there are more diff's than just block size in the Optimax family, the 2.5L models do have a few features that the 1.5L models do not, like a speedo pitot right in the leg (big whoop), probably a few other sensors/hookups/outputs, and the ability to hook 2" rigging tube right up to the cowling, etc.; so you might check on that in the 60 vs 75 4-stroke models.
