I am repowering a 19’8” Outrage (I think this was called the Outrage III). I am in Wisconsin and I bought this boat without a motor. I am looking for and I plan on buying a used EFI Yamaha. For this Whaler is a 150 hp motor adequate, or do I really need a 200?

Just about everyone here is going to tell you that a 150 is not enough motor for that hull. I have a 2.5L 150 EFI Mercury on the back of my 20 Outrage and I think it is fine. I have a t-top and the leaning post livewell option and my 150 will turn a 17 pitch prop 5600 rpms with two people on board. My max speed is 38 knots, cruise is about 27 knots. I can't complain with those numbers. I think a 200 would give a few more mph on the top end but that's about it. I'm comparing two motors with the same displacement. If you have Merc rigging I would put a new 175 Opti on that boat.

By far the best thing you can do to that boat is put trim tabs on it.

ps: I didn't know it was legal to posses a Yamaha motor in Wisconsin.

You would think that if I am between Brunswick in Lake Forest and Mercury in Fond du Lac, someone would make me a deal. My boat is rigged for Yamaha and most of the used Merc’s around here are 20 inch-shaft motors. Are Yamaha controls compatible with Merc’s? Who sells the trim tabs and can I install them myself? I thought the trim tabs were only needed for heavier 4 stroke motors.

If you are rigged for Yamaha then that might be the best choice. A F150 or 150HPDI would be a nice motor for that boat.

As far as tabs go I think they are mandatory even with a lighter two stroke outboard. You can install them yourself and Bennetts were a factory option.

Whalerparts.com has all of the "blue prints" for that hull still available. These prints show all of the factory options.

I have a merc 200 offshore on my 1998 20. The 200hp gives me you plenty of power. So far I have topped out at about 43 knts. this was with half a tank of fuel and 2 people. however I have not had the boat out on compleatly flat water/calm water yet. I usually cruise between 20-27knts depending on condition. My boat does not have Tabs as of yet, but they are on my short list of projects. The engine is a gas hog when running WOT, or at higher rpms.

Wiscbw -

I sold my 1998 20' Outrage about a year ago, but it's performance is still fresh in my mind. I had a factory T-top and leaning post, and ran an Evinrude Ficht 175. Top end was about 39 mph, and I was very happy with the hole shot and top speed. I pulled wakeboarders and skiers with no problem. However, it just seem like the 150 is getting a little on the skinny side with horsepower, and you also need to think about how some future buyer might regard the low HP if (when) you get 2-ft-itis.

Also, in my experience the tabs are a necessity on the 20'. I bought mine without them and added them later to cure the porpoising I ran into in many sea conditions. They aren't the easiest to install on the 20' because of the curved transom; I carefully machined up filler panels from "whaleboard" to provide a flat surface for the tab hinges, but it was well worth it. The 20' Outrage is a great boat.

I have a 96 Outrage 19/20 with a 150 Evinrude. I don't find it underpowered at all. I would say it's up to you what's more important--better fuel economy/greater range or more power. In anything other than flat water the top speed difference is going to be pretty meaningless imho.

Can someone tell me under what conditions you find trim tabs to be important? So far I have not seen conditions that cause me any concern.

My boat likes to porpoise in anything over about 3 foot seas. Especially if I have any of my fat buddies in the back of the boat. Basically the boat needs more throttle to keep the bow down but then I'm going too fast. With tabs you can stay on a plane at a slower speed and use the bow to slice through the waves. When I go offshore for a dive I always put as much weight forward of the console as possible. This cuts down on the porpoising a bit.

According to Whalerparts.com 9x9 Bennett trim tabs were an option. There is a flat area on each side of the stern for the tabs to mount to. I have noticed that Bennett doesn't sell 9x9's in a kit. The closest would be the M80 sport tabs that are 8x10 inches. Another option would be to hail the Tabman on the Florida Sportsman website and get him to sell you some 9x9's.

My two cents:
97 OR 20' with a 175 Merc EFI powers the boat quite adequately.
I would highly recommend the trim tabs (I have Bennett), they made a HUGE difference in my case. Up on a plane MUCH quicker, nice for offsetting passengers, torsional tilt, etc.

Thanks for the comments. With an EFI motor will there be a noticeable difference in fuel economy at a given cruise speed between the 150 and 200 hp? A would expect a third plus increase in fuel consumption at WOT, but little difference at cruise. Or is there an overall fuel consumption penalty for the bigger motor? Now the tough part is finding a good used motor.

After asking my fuel economy question for different hp motors going at the same cruise speed, I realized that this question belongs in the Whaler Performance section. So I don’t have multiple threads, if anyone has comments on this topic please post in http://continuouswave.com/ubb/Forum4/HTML/004075.html

Again, thank you for your comments on my original question of which sized motor is the best overall choice for my Outrage.

We bought a 1998 OR-20 about 3 years ago. It had a Yamaha 200HP Salt Water Series (2 stroke/carburated) and no trim tabs. The power was fine but it was a 2 stroke and we were spoiled because our 13ft whaler with a 40HP Honda was so quiet. I found a Yamaha F225 in Canada for $12K and sold the 200HP 2 stroke for roughly half that amount. The Yamaha F225 is worth every penny. Just turn the key like your car, no smoke, minimal noise and max power (225hp/2200lbs=under 10 lbs per HP). The boat is very efficient at cruising speeds 25-30 mph. WOT=44-47mph. Most of the time you don't need the power but its nice to have when the boat is full with 7-9 persons on board. The negetive would have to be the weight of the F225 Yamaha. At clost to 600lbs it is no light weight, BUT we were able to remove the oil tank which saved a few lbs and there is no need for a kicker motor for trolling. The transom is high enough that the scuppers remain above the water line. Trim tabs were added to offset the stern weight bias of the four stroke. As mentioned 9X9 inch tabs were what BW normally used. We opted for 12X12 so they would be more efficient-it works-barely. Lenco makes an edge mount tab which will just clear the bottom of the swim platform. Lenco tabs are electric so there is no reservoir which saves a couple pounds too. This combination has worked out very well. If your near Topsail Island, NC in the spring I would be happy to show Wiscbw or any other OR-20 folks our boat. As has been stated many times by people who are much more knowledgable than myself...it is recommended that you power your BW with the maximum HP allowed. In this case it would be 225HP. That way you have the HP reserve when it is needed and your engine will likely last longer because it doesn't have to work as hard the rest of the time. Good luck and Merry Christmas to my CW pals.

I run a 20' Outrage and the reason I bought it was that it came with a 225hp Yamaha Saltwater Series II. This motor is very light for it's hp range, pushes the boat extremely fast, and is pretty bullet-proof. It's an EFI but you can pull start it in an emergency (some modern EFI's require battery power to inject fuel). If you can afford it, get the highest HP. Trim tabs make a big difference with regards to hole-shot, and cruising efficiency. My pal Whaler1, Sal Dimercurio recommends the Stiletto Advantage II prop ... and he's right ... much better than the Yamaha SS prop. You can feel the boat lift out of the water with the Stiletto! I run a 15hp kicker on the back as a backup on the ocean and for trolling. This boat is very 'ass-heavy' and thus the need for the trim tabs. Good luck with your choice.

BTW Wisconsin, you have a nice Medical Center in Madison. You know, Twin Cities Marine is in your neck of the woods. I picked up a large Whaler from Al, and towed it back to Michigan. Maybe he can help you ... he good ... but he's not cheap! Take care.

ddindetroit, thanks for your comments on the Stiletto Advantage II prop. After I find the motor, the prop is my next job. I am primarily looking for a 200 or 225 Yamaha EFI. The trim tabs are on my short list after that. I am considering lenco electric tabs but need to check them out. I live in Madison, and it is a very nice place (especially when the ice is off the lakes). Still searching for a motor, and I have been in touch with Twin Cities Marine and many other marinas around the Midwest.

FIND A YAMAHA 0X66 EFI 225.LENCO TRIM TABS 9X12.
YOU WILL HAVE A GREAT BOAT. 150 IS UNDER POWERED.YOU WILL NOT BE HAPPY.
