I would consider a Yamaha F70 @257 pounds

And a Yamaha F8hp kicker @85 pounds
or a Yamaha F9.9hp kicker @89 pounds

---

how do honda 60s compare to yamaha 70
i like yamaha but lots of hondas in hawaii

You can view the complete lists of weights here on our site.
Take some time and look around.
I already gave you the link for all the Current weights so you should be able to come up with the answer yourself by reading that link.

thanks Joe
sorry
Yes it is a 17 ss ltd
I knew the weights of the engines but wanted to know if there was room for twins and also max weight for transom
literature says 100hp but that was refering to too fast an engine and or too much or transom weight
ill look for transom weights on your website for the boat
i thought it was around 400 lbs
thanks
sorry

The Honda 60 would work in place of the Yamaha F70 as you probably found out on that link.

Honda 60 @239 pounds
Honda 8/9.9 @98 pounds
Total = 337 pounds

Yamaha F70 @257 pounds
Yamaha F9.9 @89 pounds
Total = 346 pounds

I had an Evinrude 70 @248 and an Evinrude 8 @58 pound for a total = 306 pounds
on my prior Classic 17' hull.

Yes, I have seen twins on a couple of Classic 17' models but the one I know of removed them and replaced it with a single Honda 75 @359 pounds. The Honda 90 weighs the same.
Both of these weigh considerably more then the 60hp model.

Just my opinion but as is commonly stated, with the reliability of the modern outboard the necessity for twins is a thing of the past. The only reason I would want a kicker on my 1984 Montauk 17 is so I could slow down for trolling but I have found its a lot cheaper to just drag a bucket. Get a good Boat/US or Seatow policy and spend the other motor money on beer. By the way, I replaced an old 2 stroke Yamaha with a new E-TEC 90 and it's definitely not too much weight. Also it has kick you in the rear acceleration and top speed is scary.

here is the real challenge with twins on a 17 footer, the HP to weight ratio doesn't make sense. Your hull has a max of 100HP and a minimum of 35HP. That means lightly loaded it takes 35HP to get on plane. Doubtful you would plane on a single engine and your stern would be very heavy. Your better off if safety is your issue, getting a new 90HP and a small kicker although the kicker will likely not make much headway in the rolling surf. New engines are a lot more reliable than the older ones.

---

You can put twins on a 16'-7" hull. But as pojnted out already, weight is the limiting factor. Your best bet would be a pair of old OMC 35 HP two strokes which are cheap, plentiful, reliable and powerful for their small weight. But they are old two stroke technology.

Being in Hawaii you might want to check with your Tohatsu dealer. Tohatsu of North America only imports the "new" technology outboards but in Australia and other parts of the world you can still buy the carb 2 stroke engines. A pair of 30 hp Tohatsu 2 strokes would be a good match for you. Ii believe they weigh about 110 lbs.
Log on to Ebay Australia and type in Tohatsu and you will see all the old style 2 strokes still being sold. They make a short shaft 50 hp manual start that weighs about 150-155 lbs that would make a killer engine for a 13 Whaler.

I think putting twins on a 16/17' Whaler is unwise, as the hull was never meant for twins, to say nothing of the rigging complications. With new 4-strokes, you would need a minimum of 40 to 50 HP models, and they are too heavy.

For offshore use in a hull like this, you simply have to use, and should have, an auxillary.

The recomendation to consider Tohatsu is a good one. Their TLDI 3-star 90 is an excellent engine, at least as good, if not better (especially fuel economy), than the E-tec 90. But if buying new, either would work for you. The Tohatsu/Mercury 4-stroke kickers would then be your matching kicker solution, 8 HP version. With either brand, Tohatsu or Evinrude, you could then keep your overall transom weight to around 400lb, which the hull can handle.

Back in the mid-eighties, I was in your situation, using a 16' Whaler Nauset with an 8HP kicker. I did a lot of fishing up to 15 miles out on Lake Michigan. I finally decided the boat was too small, and unsafe, for this kind of serious offshore downrigger trolling, and using a kicker in big offshore seas, should it be needed for a 15 mile return, not smart. So I bought an Outrage 18 and put twins on it. The difference in comfort, and perceived and real safety, was huge.

I understand the perceived and real safety Finnergan is speaking about, as I have been just over 20 miles offshore out of port everglades on my brothers 2001 12 sport with a mercury 2 stroke 40hp, that was based on gps to the whistle bouy which is about 1 imle out of the port. 7mpg bringing 12 gallons (2 6's that fit under the bench as well as the battery made for plenty of gear including 2 cannon down riggers, 2 tackles boxes an, an a cooler converted into a aerated live well an a cooler in front of the console in the center for our catch.

Summer dolphin fishing can be flat calm in the morning an 3-5 on the way in.

Another way we could tell we were 15+ miles out was visibility, usually you loose sight of land depending on clarity.

Never once did I feel like the motor wouldn't start or we were unsafe (I was 18 year old an my brother 14 at the time)

An it was age.

We also had a 17 outrage II, that I didn't ever take out without my dad because I didn't want to be responsible for a boat that large an costly.

I felt much better in that thing then I did the sport. But when I was just a kid in high school I didn't have the fear.

I have it now, but still we go out, now I just feel queezy an un easy.

Oh and my kicker motor or back up engine comes in at 250 HP motors that are attached to a sea tow vessel. Dont drive out the inlet without sea tow or tow boat us. I use sea tow because they offer me a nice active duty military discount.

I have a 17" Montauk with a 90 hp Yamaha 2 stroke with a 6 hp 4 stroke /long shaft mounted directly on the starboard corner. I removed the lift eye so I could get it a little closer to center. Very pleased but if I were to re power tomorrow I'd put an F 70 on her.

Twins would be crazy...
