Light is right, but I believe Merc's new 115 Command thrust is much more motor than the etec 90. I think you'll find it closer to the etec 115 in performance. It's a 2.1L with gearing that allows more considerably more prop. I'm pretty certain the etec 90 would perform similarly to your Yammie. A hair slower WOT perhaps, but excellent cruising torque curve and economy, incredible economy through manatee zones.

"bitsamonkey" had incredible numbers from the Suzuki 90 on his 18,also...

Thanks for bitsamonkey's link, the numbers look really good but the question brought up about staying up on plane at lower speed was not addressed and I would also like to know about that. The command thrust is slightly heaver at 363lbs. but that's still doable, if I relocate my starting battery from the transom compartment to the console it should float at an identical level its at now and she's sitting just right.

Anxious to hear more about the subject, please keep it coming.

I can plane at about 12 knots/14 mph with a carburetted Yamaha F100- a glorified 1.6 liter F90 on a 20 foot master angler and a 4 blade prop and aquashield. Before I added the T-Top, it would come off plane at just over 10 knots. I have a 12-3/4 x 15 4 blade prop- the $100 Solas Amita 4.

It isn't the 18, but I thought the data point might be relevant.

Edit: I want the inline Etec 90 for my next outboard, if it is really 10-15 hp more power than nameplate..
