Has anybody tested a Yamaha 150-HP 4-stroke on an Outrage 18? I remember a few people offering to be the guinea pig.

Sure looks like a great match for the Outrage 18, Tom.

Could be difficult to get an advantageous price this early in it's market cycle.

Hi Tom,

After a long wait, my F150 finally arrived a couple of weeks ago. My Outrage 18 is at the dealer and he is rigging as we speak. I will gladly share the info with you all when it is in the water. The performance reviews on the Yamaha website look pretty good but there is nothing better than first hand experience. anxiously waiting...

Sterling,

I should be getting the boat back later this week so I'll know more then, and after I take it out and get it wet I share the info. Thanks...

Ron, Interested in how the engine's weight affects the waterline or static trim of your Outrage. I have a 150 Evinrude, and would be hesitant of putting much more than 400lbs on the back of my Outrage. 18 Seems the two splashwell drains are real close to submerged now. Performance figures are going to be intresting, as I am going to need repower soon.

Thanks

I have 610#'s worth of engines on my Classic 18 Outrage, and even worse, set back 10" on brackets, plus a battery in each corner of the splashwell. No oil injection tanks are used with these engines. But static trim is not a problem at all, and I've never had water get to boat floor. Even the splashwell rarely takes any water over the back.

The static trim can be seen in photos in the Rendezvous and Sail -Logs sections of this website, for those interested.

I would think the 500# Yamaha 150 would not be a problem. But left unplugged, as most do with the 1 1/4" splashwell drains, there will be some water back there. I have plugged mine, and use an 800 GPH bilge pump instead. My 1986 boat model has the small sump within the splashwell, resulting in three transom drains. I know this was eliminated in later models.

Kingfish...thanks for the info


Wilde...my 84 Outrage has the same three hole setup in the splashwell as LHG's. However, I moved my batteries up under the console. This will help with weight distribution so I'm not too concerned with the 500lbs the F150 will add.

I have a 84 also, middle drain constantly under water, two "side" drains has water splash in while rocking on the morring. I put the bilge pump in the deck sump, are you guys saying to plug the two side splashwell drains and let rainwater/splash find its way into the center splashwell drain? I haven't thought of that, I only run one battery in the splashwell, so moving it to the console makes sense to free up 40lbs on the transom.

Thanks guy's, awaiting the "shakedown" results on the Yamaha, I have been considering the Johnson 140 4 stroke.

Hello all,

Well today, we (the dealer and I) put the Outrage 18 in the water for the first time with the new F150 on it. We cruised around in S.F. Bay this afternoon and put almost 2 hours on the engine. The first hour was limited to less than 2k rpm but during the second hour got up to 3k rpm for a while. At 3k rpm, boat speed was 24 mph and the engine was so quiet that you could talk in normal speaking tones with each other. The engine runs very smooth and quiet at all rpms encountered. Today we used a 13 3/4 x 17 stainless prop and I also have a 14 x 19 prop to try on another day.
The static trim was not adversely affected. At rest, the small sump in the center of the splashwell had water in it but the two outer drain holes did not get water until we were slowing down from plane. As I put more hours on the engine I'll give more info but today's grade was A+++ overall Awesome.

Ron,
That's great to hear.

Are your batteries in the splashwell or in your console?

We took the Outrage out yesterday for its maiden fishing voyage and to put some more break-in time on the F150. The motor ran flawlessly throughout the RPM ranges encountered. I got it up as high as 3700 RPM, as well as trolling for stripers for a while. I put four more hours on the motor and could not be happier, and the boat was christened properly by catching fish too. This time, I used the 14 x 19 aluminum prop and it seemed to be just fine. However, when I can afford it, I'll get a stainless prop and use the aluminum for a spare. Overall, a perfect day.

Lou--Please stop posting these "bump" articles.

Ron--Thanks for the data on the new Yamaha 150-HP 4-stroke engine on the classic Outrage 18. If you collect some more information I am sure others will be interested to hear about it.
