I am about to buy a new Flyfin 1700 and have the option of a 90hp Yamaha or a 100 Suzuki.
The Yammy is 9.5k on top of the base price package where the Suzuki is only 3.5k.
What are you running, how do you find it, and what’s your opinion on which one I should get.

i have a 100 suzuki now done 134 hours have nothing but good things to say about it .It is the second suzuki i have owned and i have found both to be very economical. i usually travel at about 4000rpm which gives me a speed of about 20 nautical miles per hour and uses approx 9 litres per hour. this is on a 5.65 mclay centre consul with 2up  for example fishing trip yesterday travelled 36k and used 9 litres. i am sure either brand would  be just as reliable

Hi LF-just depends on your opinion as regards cam chains or cam belts?? Yamaha has a cam belt, Suzuki has a cam chain. Now as an ex mechanic including having worked on a few boat motors I have seen the results of a cam belt break....it is nasty...smashed valves, pistons etc. Having said that those breaks were on car engines, not OB's so you can make the decision for yourself. Personally I don't go near cam belts. In your case I would jump at the higher hp especially if the price between the two is similar? More hp is always nicer.

Which 100 Suzuki? There's the DF100B which is a 1.5L block (shared with the 70 and 90) and a DF100C with a 2L block (shared with the 115 and 140).

The Yamaha is a 1.8L block. Obviously a 1.5 making 100hp is going to be working harder than a 1.8 making 90.

We have a 70 Zuk that's approaching 1000 hours and has been bulletproof. Literally zero issues, all it's ever needed is petrol and servicing every 100-120 hours. I will say it is much louder than my friends Hondas, especially if you give it some throttle, and produces considerably more vibration.

That price difference is a whole lot of fishing money, maintenance money etc
I'd be going the suzuki myself, smaller block sure but how often do you run full noise. 

Disclaimer, Df100b is sitting on the back of the 4.5m boat in the garage, no issues that have been the motors fault (only done 100hrs) boat before that had the 90 suzuki same block and it did 550hrs with no faults before the boat got sold.

Just to wade in on the cam chain / belt issue 
While its true that a broken cam belt can destroy an engine........ so can a broken chain . A  belt on an outboard is relatively easy to get at   not like most cars   so a lot of the labour bill is reduced .
 A cam belt can be inspected without any major work to get an eyeball on it  ditto for the tensioner and idler pulleys 
 Cam chains are much harder to inspect  but they last much longer. They also involve a lot more in the way of tensioners and guides .... they are not as bullet proof as some think  . If the tensioner or the guides fail  your in as much 5hit as a failed belt. chain guides do wear and in some cases disintegrate to the point that the chain gets loose  and starts hitting the inside of the engine cases  and/or jumps a tooth or two  and then we get valves hitting pistons . This is more likely in an outboard than a car as the outboard chain runs horizontally   and a car chain runs vertical. 
It took me 1/2 hour to change the cam belt on my honda outboard, and not much longer to do my Ducati ( two belts )  Changing a cambelt is no more technically challenging than assembling a Kinder surprize toy ........just getting at the thing can be an issue , best take it to the shop if patience and skill dont rise to the occasion .
 Both my cars have the chain   and Im quite happy about that  but the Rav4 has 180,000kms on it so I an soon to take the top cover off the engine and have a look see ..... I am expecting it to be OK as the car has been well serviced ( by me Big smile )
Personally I would go for the belt .... specially on an outboard . I will say tho that being able to do the work oneself  will influence any decision . I will also say Im nearly at the end of doing cambelts for friends cars  .
I wish I was young again .... Id be heaps smarter than this time

Flyfin 1700 Is a 5.2 metre boat so a 90/100 will go well, Yamahas 90 had been around for years and their 4S 90 is just as reliable and has a few more cubic which is an improvement.

I had Suzi over the years very good outboard and I don’t think belt or chain makes a big difference I prefer chain but that’s only a personal thing.

The Suzi will be fine in the gulf but you need to look for a good service agent, I think Yamaha has better coverage in Auckland.

On my second Suzuki First one a 60 and now a 140. zero issues with either. 
I'd look at weight and CC as well as price. A good reliable service agent is also a major consideration.

Been a few go under so the ones left will sell and service anything to keep the dollars coming in the door.
