1976 Evinrude 15hp vs 2000 Tohatsu 9.8hp

I'm considering picking up the Tohatsu after owning a few Johnson/Evinrude 9.9's and 15's .
Main reason for the upgrade would be weight . I assemble and transport every outing.
Seller claims the 2000 Tohatsu is faster / better than any old Evinrude 15 because they measure at the prop while the Evinrudes measure at the powerhead somewhere around 12 hp.

Someone told me once, there is no replacement for displacement
2000 Tohatsu is 169 cc @ 57 lbs
The Johnson / Evinrudes are 215 and 255 cc respectively @ roughly 70-80 lbs

Would a 1993-2007 Johnson Evinrude 15 be a better purchase ?
or would the 2000 Tohatsu be a better purchase ?
To me, weight savings would be significant if the power is the same.

Would I notice a big difference between a newer 1993 -2007 15 than my older 1976 15 ?
or would the power be the same across the board more or less for all 3 outboards ?

The boat would be a 10 ft soft bottom inflatable weighing under 100lbs .

The 93 and up Johnson would be my choice.----Prop rated and smoother running ( different intake ports ) on them.-----Too much plastic on them.------I think the 1984 OMC are the best and parts donor motors can be found easily.

A 1993 and up Johnson are 250 CC motors compared to just 169 CC of the Tohatsu. No, cant bump a Tohatsu 9.8 to a 15 HP one, are different animals. The good thing about having too much plastic is that can remove both lateral covers and retorque the cylinder head and exhaust cover without needing to remove the whole powerhead from the pan...

Is there really that much of a difference 169 cc vs 255 cc ?

I'm going to stay away from the Tohatsu then.

Not worth sacrificing a ton of power just to shave off 20lbs .

For the ones that haven't tried running both CC motors powering medium light large applications 86 CC is a lot of power to count with and not need than.., you know the rest. Go for the larger HP motor, doesn't matter if weights more since you'll be sacrificing power against portability.....

Thanks. I'm going to focus on a 93 and up 15 hp because I can still lift them easily.

Some people cant , physically lift 80 lbs , maybe age, or a bad elbow or shoulder , ect.... and so they opt for the lighter one.

Wise decision, a higher 15 HP motor will push/plane whatever floats much better than a 9.8 HP one...

I currently have a 76 15hp.

Once I find a 93 and up , I should notice an improvement in overall performance. Bigger displacement, larger exhaust, stronger spark vs points and condensers, improved reed valves, and it should be a lot smoother overall

The intake ports on the 93 and up models are different.----Results in better scavenging.-----

Your preference are the 88 - 92 motors ?

Better overall design and simply more junkers available ?

I like the older ones.----I am not fond of the ones with the cable in the tiller handle.-----Too many beer tokens for some of those pieces.

I personally like the Cable tillers better. On the older ones the tiller always has to be inline or you risk breaking expensive gears. The cable tillers allow more flexibility and they are longer so more comfortable.

Have a few extra inches on the tiller would definitely help shift more weight to the center.
