That is a really good point. Suzuki have not really been on my radar. That's for the advice.

The etek 75 and 90 are basically the same engine so I would go for the 75.

But then there is the 90HO which is about the same as the 115. It is 4 cylider, has a lot more grunt and, because the gearbox and iternals are designed for higher output, it is more reliable.

I would check the price difference between 90 and 90HO ....

90 hp ho is too much weight on the back of a 5 m rib

Well it weights about the same as any 80-100hp 4 stroke...

It is about 30kg more compare to the 75 and 90.

If too heavy, go for the 75hp

And (IMO) the Etec will blow any equivalent 4stroke into the weeds. When it comes to torque & low down grunt the Etec will win every time.

That sound perfect. I will check it out. Great advice Thanks!

If the 90HO is based in the 115, it will be considerably heavier than the 75-90

Ummm. Maybe I had better loo out for an Etec 75. I may know of one.

I'd like to see a tug of war between the two motors, on identical boats...You might be surprised with the result...

I might be very surprised [emoji57]

How the etec 75 (90) was developed during its history? When the reliability was increased if any? Thank you, experts.
