I'm contemplating buying a 2005, Boston Whaler 190 Nantucket with the 135 HP Opti-max Mercury. We are a family of 5 (2 adults, 3 boys 5, 7 and 13). The engine has 200 hours. Would the 135 HP engine be enough for some water sports such as tubing or wakeboarding?

You'll be fine, my Dauntless 180 with a Verado 150 pulls my son and a kneeboard, wakeboard like he's not even there. Thats with 3 Adults and 1-2 other kids on the boat

When I bought my 04 Nantucket in 2005 it had a 135 salt water series optimax. I had it for the first season and put 60 hrs on it.It ran flawlessly and had plenty of power with 5 or 6 people out for a ride or pulling tubers.
I traded it the next season for the sole reason of NOISE LEVELS.At 3500+ rpm it was too loud to talk to someone standing beside you at the helm and at idle it clacked away which was annoying when fishing.
I now have a 150 Yamaha with 450 hrs. It too has been flawless and importantly to me and my passengers....very quiet.
Its about 40 lbs more than the Opti and I would say that the Optimax 135 seemed to be as powerful. If it wasn`t so loud I would have kept it. It is a very light motor which is good for the 190. The 150 Etec might be the perfect motor for the 190 as its even lighter ...but I went for the proven 150 Yamaha.
Some people like the throaty growl of engines but I don`t.
It would be best to test drive the boat to see how you like it.
A neighbour here has a 200 opti on a 20ft alumacraft and they wake board and always have 6 or 7 people in the boat too. You can hear him coming from a mile away.
Last cost me 6k to upgrade from the year old 135 opti to the new 150 Yamaha four stroke. Alot, but its been worth it.

Thank you Kencvit! Wow, that's a big show stopper. Coming from a sailing background, the engine noise is a big problem for us. And to have an outboard noiser than the other ones it's a big no no. I have to look now for a boat with a four stroke engine.

I would not edit all 2-stroke engines from your search. I was next to an Evenrude E-tec 150 at the launch last week and it was quieter than my 4 stroke merc 115. Good luck on your boat hunt!

Just make certain to sea test any boat and motor you are considering before making a purchase. Make certain you are able to run the boat under conditions that best approximate the type of boating you will be doing. Idle, run the boat at high speed, etc.

In this way you will be able to make an informed decision.

I would not discount any motor until you have an opportunity to try it yourself.

Good luck with your search.

I'm not giving up on the boat yet. In fact, I'm travelling on Monday to give it a run. Not surpringly, the dealer thinks that the engine is not as loud as Kencvit said (to put it mildly). I did some research, I've talked with other people and there seems to be a consensus that the Optimax Mercs are louder than a 4-stroke Evinrude or Yamaha. However, they said that at cruising speed is usually the wind that affects a conversation and not the noise of the engine. That being said, I'm still going to try that boat.

The problem is that most of the Whalers on the market (within that range) have a Mercury engine and I do want a Boston Whaler. For the same price I can get a Sea Hunt Triton 207, 2 years newer, 2 feet longer and with an Yamaha F150 4-stroke engine. However, I have a feeling I might regret it if I choose it instead of the Nantucket.

I think I read somewhere that the Opti 135 was louder than the 150 and even the 225.
A sea trial is your best bet...maybe you won`t mind the sound levels
While at the docks there maybe you can have him start up a verado or yamaha 4 stroke to compare. Verado`s at idle are super quiet, quietier than the yamaha,but heavier by 60 pds I believe,and not as reliable or trouble free as the yamaha( based on what I`ve read on this and other discussion boards).
As well the verado was a more expensive option than the yamaha when I upgraded.
After the dealer tells you how much HE likes the 135, tell him you want to trade it in to him and upgrade and watch the value drop.
Maybe offer to buy the boat only.
We cruise at about 3000-3500 rpm on average and I can stand at the side of the helm and talk to someone sitting on the bow cushion. Try that with the 135.(wind or no wind)
I`m not saying that the opti is a bad motor. It ran very well, had lots of power and got very good mileage. I just found it to be unacceptably LOUD. Especially for a new modern high tech motor.
If you have an upgrade option the E-tec 150 would also be an excellent option for the nantucket hull with its light weight. Reports here and elsewhere say its also very quiet. I`ve heard them on the lake here and they are quiet, I have not heard one, a 150, at idle at the dock.
More power than the yamaha too acccording to the E-tec site. The website is definately impressive and the reduced maintainance costs of the e-tec are obvious over the 4-strokes.
But with 3 seasons and 475 hrs and not a single problem or even a hiccup from my F150, I will remain a yamaha owner.

IF you buy it and it doesn`t already have one...the first thing you should do is order the Mills forward shelter. A must for this boat if you are out with your family or kids.Everyone and towels etc stay dry and safe protected from wind,sun and rain.The stern quarter seats have backrests that are too low and I have visions of someone falling out over them. Besides the nantucket rides better with the weight and passengers forward.
