E-TEC 150-HP: G1 v. G2

Postby jimh » Thu Jun 30, 2016 11:29 pm

Here is a rough comparison of weights for an E-TEC 150-HP engine in either legacy (G1) 2.6-liter 60-degree V6 and new (G2) 2.7-liter 66-degree V6 configurations.

WEIGHTS (lbs)
-G1- -G2-
Engine 433 541
Steering 15 0
Oil Tank 5 0
Set back 35 0
ETS 5 0
TOTAL 493 541


The weight difference at first looks quite big, 541-lbs compared to 433-lbs or an increase of 108-lbs. But if we consider the weight of the steering actuator, the oil tank, the set back bracket, and the eletronic throttle and shift (ETS) which all are integral with the G2 but would be added to the G1, the weight difference drops to 493 versus 541, a differnce of only 48-lbs. For that extra 48-lbs the G2 gives the boat Dynamic Power Steering, I-Trim, significant improvement in fuel economy, improved torque and horsepower, and vastly improved emissions. From this perspective, the extra 48-lbs of the G2 is not intolerable.

If you want to head-to-head comparison without any allowance for steering, there is a 150-model with no integral steering. That G2 model weights 507-lbs. Head-to-head with the G1 at 433-lbs, we have a delta of 74-lbs increase, and we still get the set back feature. Include the 35-lbs for the set back in the G1, and the difference is down to 39-lbs. Add the 5-lbs for the ETS and 5-lbs for the oil tank, and the difference is now 29-lbs. There is no way 29-lbs makes a big difference.

[I wonder] about the cost difference.

I have not seen any official price data. I have heard informal comments that the cost of a 150-HP-range G2 compared to a G1 will not be more than a few hundred dollars, on an apples-to-apples basis, which I assume means the G1 would be upgraded to ICON ETS electronic throttle and shift controls. If the cost of an external hydraulic steering cylinder and possibly a short jack plate or set back bracket is also added to the G1 cost to get a more equal comparison, I don't think the G2 cost will be very much different.

Considering the substantial improvement in features, in performance, and in fuel economy, an initial cost disadvantage for the G2 ought to be quickly recovered in greater enjoyment and saved fuel expenses.

Both are too heavy for my 1999 Dauntless 18. When I re power I will have to sacrifice two-stroke power for four-stroke weight savings.

If a legacy E-TEC V6 150-HP at 433-lbs was too heavy for your boat, what V6 150-HP four-stroke-cycle outboard weighs less? Oh, wait, there are no V6 four-stroke 150-HP engines.

Even the four-cylinder four-stroke-power-cycle engines weigh more than the E-TEC, for example the Mercury 150 FOURSTROKE BASED ON 3.0-LITER BLOCK at 455-lbs. I don't think there is any modern engine that you can use. I think you are out of the re-power business based on your weight criterion.

Suzuki 140hp. Not a V6 nor 150hp but I must factor in the weight of my jack plate (which I love and can't do without) that weighs about 30lbs.
That said my trusty 1998 Evinrude carbed 2 stroke is the best motor I've ever owned. Hope it lasts forever. It is perfect for this hull.

How much does the Suzuki 140-HP weigh? You never really say its weight.

The Suzuki 140-HP is their high-performance version of their 115-HP engine. If you are satisfied with a high-performance 115-HP derivative engine, wait another year. Evinrude will probably have a V4 version of the second generation E-TEC engines available; it should weigh less than the V6 version.

Although the 140-HP Suzuki is their best selling engine, I don't think it can compare in performance to the Evinrude 2.6-liter 60-degree E-TEC (G1), and certainly not even close compared to the Evinrude 2.7-liter 66-degree E-TEC (G2). An engine weight difference of 26-lbs (433 Evinrude v. 407 Suzuki) seems rather insignificant. But, if you want lighter engines in the 150-HP class, you will have to get a four-cylinder.

Agreed.
Hopefully I won't have to worry about for a while and if and when the time comes BRP will have some sort of G2 version in the 135hp class.
