1996 Outrage 19 Re-power

Postby Pescado » Tue Apr 27, 2021 10:35 am

In 2015 I was fortunate to find a lightly-used 1996 19' Outrage with a 1996 Mercury 150-HP two-stroke-power-cycle engine. The engine is still operational and I have not had any concerns with it. The only reason to re-power is that I consider the 1996 19 OUTRAGE boat to be under-powered at 150-HP. Stern weight is a concern on 1996 19' Outrage; the scuppers have a tendency to let water in when fishing and fill the generously large fish boxes. My research of new engines has produced these preferred engine choices:
  • Yamaha 175 VMAX
  • Yamaha F200
  • Mercury 150 ProXS, and
  • Mercury 225-HP V6 FOURSTROKE.

Q1: For the knowledgeable people on this forum that know this boat, what would be your re-power engine choice?

ASIDE: that Evinrude no longer produces the lightweight legacy E-TEC V6 200 engine is a shame. That E-TEC would be a nice fit for this boat.

If the boat already allows ingress of water into the cockpit with the current engine weight, to increase engine weight seems like moving in the wrong direction with regard to that problem. Thus I must ask:

Q2: What is the weight of the current engine?

Q3: What is the specified engine weight of the four engines you have listed?

The [current engine weighs] about 435-lbs. The Yamaha engines weigh about 480-lbs to 490-lbs. The Mercury engines weight less than 500-lbs.

Extra weight will be put on the transom.

Q4: What other engine choice is available for re-power?

The 1996 Outrage 19 is stock with not a lot of weight added--no T-Top.

[When I am not aboard the boat] the scuppers are plugged. [When I am aboard the boat] I put some weight on the bow for security.

If others with the same hull might say there is water ingress when on the water and guests walk around the boat.

I do not recall the exact specification for transom weight by Boston Whaler. It may be close to 575-lbs.

The 175 VMAX would be a nice engine. Would I see much improvement over the current 150-HP?

The F200 would be similar in performance with the hot 175 VMAX.

The 150 ProXS is a wonderful engine but a bit underpowered for this hull.

The Mercury V6 175-HP to 225-HP models all weigh the same. I would choose the 225-HP model.

There are rumors that the Mercury V6 engine weight is more than Mercury claims.

If this 1996 Outrage 19 is to be re-powered with a new, current model engine, that new engine will bring extra weight. The alternative is remain with the current engine.

Q5: What engine has been chosen for re-power for the 1996 OUTRAGE 19 by others?

Q6: What solutions for the 1996 OUTRAGE 19 for water ingress through the scuppers when fishing have been invented by others owners?

Q7: What does underpowered mean to you?

Q8: What conditions do you fish and boat in?

If you are in relatively calm waters most of the time, then wide-open-throlle is something you are probably considering as part of the equation.

I have an OUTRAGE 20 with a Honda BF150. The OUTRAGE 20 is a slightly different boat [than the boat under discussion], but wanted to give you my experience. For my use in the Pacific ocean, 150-HP more than enough power. When fully loaded with four people, full bait tank, gear, T-Top with Radar, in calmer conditions, the OUTRAGE 20 can get on plane with great ease and cruise at 22-nautical-miles per hour or faster. Wide-open-throttle seldom happens here as conditions rarely allow for it.

The OUTRAGE 20 has three [drains] in the engine well that you would consider scuppers, I only leave the middle [drain] open. The boat batteries are in the well.

When I fish the outside open ocean the 150-HP is adequate. On those voyage [the boat speed used] is not [the maximum possible] but [a boat speed that produces] comfort.

With more power, keeping the bow elevated to face the chop might be easier.

The scuppers on the 1996 to 1999 19 Outrage are designed as a self-bailing scupper. They are different than what you have described on your OUTRAGE 20 . Unfortunately, the scuppers are my least-favorite thing on an otherwise very useful hull.

ASIDE: Sounds like you are having lots of fun with your boat and thanks for your input,

For boats with the scuppers, the failure of the flap due to age is a common complaint.

You can replace the flap or install ball type scuppers. The latter being more effective at keeping the deck dry.

The 150 Pro XS is the engine for its cost. At 455-lbs it might be the best fit for this 1996 OUTRAGE 19.

The top speed would be 5-MPH to 10-MPH lower than it would be with a powerful engine, or the top speed might not even be that much difference.

With the current engine weighing about 435-lbs and the Mercury 150 ProXS weighing 455-lbs, and both rated for the same horsepower, I think the choice of which engine to purchase for re-power so as to have the least effect on transom weight is clear: the Mercury 150 ProXS

You can move weight out of the stern of the boat by moving all batteries to the console.

The boat speed can be predicted using the Crouch Speed Predicting Method. I have created a calculator to implement that method. The method requires knowing power, weight, and hull coefficient.

The effect of horsepower on top boat speed for this boat can be estimated with the calculator.

This discussion lacks useful data. In this discussion there is no mention of the boat's top speed with the 150-HP engine. I will assume the boat can hit 35-MPH.

In this this discussion there is no mention of the total boat weight. I will calculate the boat's weight by assuming a hull coefficient of 190: 4,420-lbs.

Now the horsepower needed to increase boat speed by 10-MPH to 45-MPH for a boat that weights 4,420-lbs with a hull coefficient of 190, can be predicted. However, I will add 70-lbs to the weight to account for the larger engine: the required horsepower will be 252-HP.

To increase speed by 5-MPH will require 200-HP.

Jim,

The batteries are fitted in the center console now. Your estimates of boat speed and weight are very close. This hull has a generous fuel tank, around 90 gallons. If one ever had to replace the fuel tank I would fabricate a 65 gallon tank and eliminate 25 gallons aft. It will be interesting to see what the Crouch Speed Predicting Method comes up with. The other thing going for the 150 Mercury is its hard to find any bad reviews on that engine! Thanks for your interest and time.

To increase speed by 5-MPH will require 200-HP
.
Thanks Jim

Right now I do not think the extra weight and extra money for a 5-MPH gain in top end speed is worth the cost.

The Mercury 150 FOURSTROKE has a track record that's hard to beat. Many boaters would say it is the best engine Mercury is producing.

The Pro XS has the advantage of stiffer engine mounts and a lower water pick-up. If mounted properly and set up with the proper propeller, I am starting to think a 150 ProXS will work.

The ProXS costs CA-$6,500 less then the V6 225. I can use my existing remote controls. The price of the ProXS 150 actually seems reasonable compared to the [other models based on the same block].

Were my existing engine a Yamaha I would re-power with the Yamaha 175 VMAX.

Thanks again for your useful information. Have a wonderful day.

I guess that eliminates the option to move them out of the stern.

I based them on your comments and an educated guess.

I believe [the boat under discussion, 1996 Outrage 19] is the same hull as my 1997 Outrage 20.

In 2010 I re-powered the 1997 OUTRAGE 20 with an Evinrude E-TEC 175. Performance is very good. Only on very calm days do I wish it were faster.

Even still, the 1997 OUTRAGE 20 with an Evinrude E-TEC 175 gets up on plane quickly and efficiently--even with a heavy load.

The slowest on-plane speed is 17-MPH in sloppy conditions, An efficient cruise is about 24-MPH. In calm water cruise is comfortable at about 30-MPH, but there is slight decrease in fuel economy. The boat's top speed is about 44-MPH.

This hull is pretty short and wide. The hul doesn't take very well to high speeds in rough water. As much as I would love to cruise at 40-MPH in calm water, it wouldn't be too often

I feel like a engine with 175-HP matches the hull well.

I do like the specifications on the new MERCURY V6 225 engine.
