So I'm between a Yamaha F40LA at 214 pounds or an E-Tec 40 at about 240 pounds.

I know they are both heavy but i have heard testimonies of both and it will be fine!

I'm looking for speed, some skiing, bay area cruising

The boat is a 1986 so the motor will be a 20 inch shaft.

I'd get the cheapest one!

On a 13 the less weight on the transom the better. The E-Tec has a lot of nice features and it would be my intuitive choice. However, assuming the Yamaha is a four stroke and performance would be close if not equal it would probably be on my transom if the price is competitive.

Before making a final decision I would also compare the two engine's torque and HP curves. For a water sports use higher, earlier torque is important, especially if towing more than one skier and if more than three persons are aboard.

Finally, all the new engines are very high tech. I would not want an engine on my boat that was not supported by a competent and respected local dealer's service shop.

Repo we're my 1985 13 with an Etec 30 hp. No maintenance for 3 years, self winterizing and plenty of power. Great motor.

Recently caught this vid on 30 and 40 hp engines, was surprised at the power of the 30.

Thank you that is a nice comparison link and based on the 14' boats they used a 30 Etec would be a good choice for the 13' Whaler as it will be lighter then the 40HP motors shown. The Yamaha surprised me by lagging behind.

Dave,

That was a great independent test of 3 different brands of motors.
Appears to be non-biased and even mentioned "It is what it is" at the end of the video.
I like that but everyone can decide for themselves.

I think that should show us how well an E-Tec 30 would perform on the Classic 13' Whalers and keeping the weight down.

Glad you guys found the video helpful. The other impressive thing is that even though the Quintrex hull they used is made of aluminum, the weight of that model is listed at 300kg or 660 lbs. If memory serves, the weight of the 13' Whaler is between 320 and 410 lbs depending on configuration. So from a hull weight standpoint, performance on a 13' Whaler should be even better.

I have been super happy with my Etec 30. It's power tilt / trim, gets really good fuel economy, is quiet, emits no odor and is really quick out of the hole. Originally I was looking at Yamaha 4 stroke as well but the 3 year zero maintenance, self winterization, 5 year warranty and points above sealed the deal for me.

Soo the 30 etec weighs in the 180's
The 40 etec is in the 240's
Most 4 stroke 40's(new) are 215+

How would the 30 etec compare power/speed wise to my 40 suzuki 2 stroke(1996 i think)

I can tell you the previous motor I had on the boat was a 2001 Johnson 2 stroke 35 hp and this engine feels as quick as that one was. Not sure how it would stack up against the Suzuki.

Good to know. Thanks

You might check out the Suzuki 30HP - it's 159 lbs (20", PT, remote, electric start) and significantly less $$ than the 40s. Might not have enough power for your app but it's worth a look. I bought one for my 2002 sport, but it's a winter project and I haven't run it yet.

We just sold our 1987 13 Super Sport with a 30 E-TEC. I thought it was the "perfect match" for the boat.
It replaced a 2000 Johnson 40 2-stroke. Only lost about 2-3 mph top end, but EVERYTHING else was a gain. (Quiet, smooth, instant starts, no smoke, sips gas, really sips hardly any XD-100 oil, great performance. Top end was 30-31mph with a 13" stainless 3 blade with the 30 E-TEC
There are two 13's nearby with 40 E-TECS.
My advice regarding the 40 E-TEC: Don't do it!!
240 pounds is too much. The 175-180 pounds of the 30 is actually just getting by. The splash well with the 30 had about 3" of water standing at rest. The other two 13's with the 40's had a pronounced "squat" at rest.
To make matters worse, even with engines raised, their props were in the saltwater and were constantly getting fouled, and the intakes were restricted with growth. Both owners had mentioned they regretted the decision to go with the 40's.
The boat closest to ours moved the battery and tanks forward, but didn't do enough to matter.
We have a good number of 13's in our vicinity. We were the first with a 30 E-TEC, and several others followed.
Every one I spoke to really enjoyed them. The 30 is a great companion to the 13.

The wife's 1981 Sport 13 is powered with a 2008 Mercury 30 HP EFI four stroke with T&T. It is more than enough power. The engine well drains are well above the water line. At a mooring the skeg remained in the water with the engine fully tilted out. A few weeks ago my wife added some reverse tilt adapters to offset the transom rake and allow the engine to be more or less vertical when tilted/trimmed fully down. We have not had the boat in the water sine adding the adapters but I'm confident the lower unit will be completely out of the water when tilted up fully.

The adapters may effect hole shot because the engine can no longer be "tucked in" when trimmed in fully. If so I'll change props to compensate. Frankly, even with only 30 HP and two adults plus a cooler and safety gear the boat is fast enough to be a little scary at WOT. You're very close to the water in a 13 and even 30 MPH feels pretty fast.

Totally agree with cape coder, I believe the 40 etec would be too heavy, my neighbor is running a 40 etec on his 19 foot Carolina Skiff. I have my 13 whaler sport moored on the East Branch of the Westport River (near cape cod) and the Etec population is very high, among both recreational and commercial users, seems like every other boat has one. Granted the big boat yard here sells and services them but there are plenty of other choices nearby.

im between the etec 40 and the etec 30 now

most say the 30 is enough.......
but some are saying that the 40 isnt too heavy. only a slight tilt when stopped

Is your 13 only kept on a trailer? Or is the boat kept in the water at a slip or mooring?
If only kept on a trailer, the the static trim of the boat will rarely matter.
However, if kept in the water, the 13's with 40 E-TEC's, because if the excess weight, have a substantial portion of the lower unit submerged in the water even when tilted all the way up........very UNdesirable.
One 13 in particular that I need to pass by on my way to open water had a fouled prop, and significant green growth fouling the raw water cooling intakes. A mess. (If your boat is to be used daily, then perhaps, you could keep up with the preventative maintenance)
We consistently used our 13 Super Sport with the 30 E-TEC as a taxi to a small island to enjoy the beach. Many times with 4+ full size adults and gear, our guests questioned if we would get on plane. Let me tell you about the astonished looks on their faces when that 30 E-TEC lifted that 13 on plane without a problem and zipped over to the beach.

I too struggled with this decision when re-powered. I had a Johnson 2000 40hp 2-stroke. I resigned myself to the fact that I was "settling" for a "little 30". But I must say, I never looked back because of the great performance with the 30.
One extra point. I did install a Sting-Ray Jr. Hydrofoil (like doelfin) on the 2000 Johnson, AND the 30 E-TEC. Many times in choppy water there was a true benefit to be able to plane, but at the slowest speed possible, for comfort and dryness. The hydrofoil accsentuated the ability of the trim function to allow the 13 to plane at a lower speed without the aft end squatting while underway.

what was the top speed with the 30 etec?

what difference in top speed would there be 30 etec vs 40 etec?

i would prob be cruising with 2 adults most of the time. and would like to pull a tube occasionally. would attempt to kneeboard and wakeboard too but not too much

The 30 E-TEC with a 13" prop running at 5850rpm did about 31mph.
The 2000 Johnson 40 hp 2-stroke did about 33-34
The 40 E-TEC would be somewhere near the Johnson 40
Any of them will pull a tube with 2-3 adults aboard with no problem.
