UPDATE: As soon as Washington Licensing sends the title for my 1994 Outrage 17 it will be sold. The 30-day wait will be up within a week. This boat is too nice for my purposes.

With that money, I will re-power, licence, and insure a bare, well used, 1987, OUTRAGE 19 CPD to serve primarily as a work skiff and part-time rescue tow boat on the Lower Columbia River. If SeaTow or the USCG and Local Gestapo has a conflict (on another job when you need them), they will call me.

I've spent hours shopping, studying, reading threads. In fact, I was all set to copy Dave Buckda's twin E-TEC 90 setup, but I am backing out because I don't think the 200-lbs of extra transom weight is going to work for my purposes. I am waiting for trim angles to be sure.

I know just enough about gear ratios and wheel slippage to get myself into trouble. I just run the boat and busriness and try make enough money to let the pro's take care of the fine points. hehe. On Tugs, if you drop a hundred RPM when you put 'er in go ahead, you are about right.

I have learned the 19 is NOT a good boat to mount twins on and achieve max-HP rating for the transom. I also know almost ANY equal HP single will out perform twins with rudders amidships at WOT on this hull for about one-third less money if you include the price of a new 9.9-HP kicker and rigging. BUT, IN TIGHT SPOTS, responding to a anchored, drifting or beached boat in chop, current etc., with 35 years experiance maneauvering all forms and sizes of single and twin screw boats, the twins will kick a single's butt from here to eternity. I respect a single, I NEED TWINS.

1. 60 E-TEC 240 lbs. two-cylinder two-stroke. 2.67:1

2. F60 EFI Yamaha 237 lbs. four-cylinder four-stroke. 1.85:1

3. 60 Big Foot 264 lbs. four-cylinder four-stroke 2.33:1. Heavy duty shafting, salt water approved, high gear ratio and US product is appealing.

I flat don't know which engine will serve better for the above reasons. Wheel options are important, carburetor two-stroke motors are not.

Calling a dealer will be fruitless. 1999, I wanted a short box F-350 Diesel with extended cab. The local Ford dealer head salesman tells me Ford doesn't make one. Three days later I drove one onto his lot. He smiled--I've known the guy for years--and took me aside. "Mike, honestly, if we don't have it on the lot, Ford doesnt sell it." Never forgot that one. Point is, I know a E-TEC dealer is not gonna tell me Yamaha is a better setup and visa versa. No dealer in this area sells both. Yamaha has a slight edge in this area.

I really appreciate your time/experience to comment one way or the other.

BTW, Towboaters don't call props propellers in the same context that they don't "DRIVE" the boat--they run it.
We affectionately call 'em wheels.

I would think that the E-Tecs are going to have better torque, and would do better at low-end for towing, etc.

Thx for the brief summary Plotman.
I tend to agree. But under a load...I wonder?

I run quads in the sand. The 2 stroke quads need high RPMs to "float" on the sand due to the power band. I read lots of posts trying to get X amount of RPMs WOT adjusting engine height &/or wheel pitch/dia.
Again, I need twins for occasional rescue towing which changes the setup substantially.
Is a 2 stroke more likely to burn up under a load than the 4 strokes?

review;

A. 60 E-TEC
(240 lbs ea. two-cylinder two-stroke. 2.67:1)

B. F60 EFI Yamaha
(237 lbs ea. four-cylinder four-stroke. 1.85:1)

C. 60 Big Foot
(264 lbs ea. four-cylinder four-stroke 2.33:1.)

thx

The only concern I would have about your specified duty for these E-TEC's is that they are two cylinder engines. The 4-cylinder motors are going to be smoother and also may be better by virtue of greater displacement - I do not know.

4-strokes produce better low end grunt, we all know that, but is it enough to overcome the 4-cylinders of the 4-stroke competitors? I don't know. My perception is that the differences between 2 and 4 stroke motors is less evident in the smaller motors than it is in the larger ones.

Good luck in your decision.

Dave
