Author Topic:   Another re-power question Yam or Merc HELP

2000 18' O/R

So I’m getting close to making a decision and I have it down to two choices…either a 150 4 stroke Yamaha or a Merc 200 Opti. Cost for the Yam plus all the new rigging (gauges, throttle, labor etc…) is about $500 less than the Merc 200.

So what motor do you think would be in my best interest? I’m happy with the performance of my existing 150 Opti but a little more power never hurts. On the other hand the 4-stroke Yamaha (4 cylinder) weighs a bit less and smooth quiet operation of the Yamaha is very appealing. The boat sees mixed use…harbor cruising, water skiing and some local fishing (never more than 30 miles round trip). Warranty period is the same on both motors and I’m also trying to take re-sale value (5-10 years from now) into consideration as well.

Thanks in advance for your input…I’m really on the fence on this one.

"If a little more power never hurts" is your issue, you don't want an in-line 4 4-stroke to replace a DFI V-6. As yet, there has not been a 4-stroke invented that will outperform the same HP 2-stroke or DFI, and I doubt if this one will either. You would need a Merc Project X to accomplish this, but a 150HP version is probably a year away.

I would look at a 200 EFI, Merc or Yamaha, or your chosen Opti 200. That heavy 18 Outrage will not accelerate well with the Yamaha 150. Be careful of that situation. Have you looked at the Honda 200? Someone has them for sale cheap here.

Why not check out the Yamaha 200 HPDI.
My brother has one, and I think it's awesome.
Great performance, great milage, no smoke, quiet.

Only reason I would look to the Yamaha would be to pick up the 150 4-stroke which fills a nitch that is currently a void in the Merc line-up. If I am going to stick with a 2-stroke (and that's what I'm leaning toward doing) I will happily stay with the void the hassle of changing my rigging.

I am familiar with the motor you mention and it's a good suggestion...just not a good fit for me right now

Forgot to mention...also was looking to the Yam 200 4-stroke but at 580 lbs. I think it is too heavy for the boat?? Maybe, maybe not?

Cole, what a delima and what an oportunity! You have your choice of a host of engines (makes, types, power ratings, etc) so what is best choice? If you want the most bang for the buck and pound just get a 200 Merc EFI 2S and don't look back! At about 415lbs this engine will outperform (acelleration and top speed) most anything out there and get very decent fuel mileage in the process. In my experience it is also quieter than a four stroke at speed (not at idle but almost!). The 200 Opti is a 3L at about 500 lbs and on same boat the 200 2S will most likely outperform it in all but fuel mileage. If you want best fuel economy maybe the 150 Yam 4S is the ticket, but you will never in your lifetime recover the difference in original and rigging price in fuel savings over the 200 EFI Merc even if you run the boat all day every day! Getting a new engine is a great day in the life of any boater and here's hoping that your choice suits you fine and enjoy it for all of us... Happy Whalin'... Clark... Spruce Creek Navy

PS> recommendation is the 2.5L EFI Merc and not the 3.0L. While the 3.0L may also be a good choice, it is heavier and more costly and may not perform as well as the lighter 2.5L. On a very heavy rig the 3.0L could be the workhorse of choice... Blah, blah, blah.... Clark... SCN
