Suzi or opti?

This is a very broad question indeed, but which is better in terms of, well, everything. Speed being the odvious one.

Suzuki 140 4 stroke or Mariner Optimax 225

Very different engines for different size boats for a start!

Mercury OptiMax look better than the Mariner versions I reckon.

No Im not. Sorry if this sounded like a stupid question; I should have been more specific.

We're talking about a 7m RIB here, nothing heavy duty like an Arctic 22 - just a normal 7m RIB.

I'll throw my thoughts in here for people to comment on:
Suzi is much more economical, it is a 4 stroke so sounds quiter and smoother. Speed will be in the reagion of about 35 knots I would imagine.
Opti is a much bigger engine. I would imagine top speed would be around the 50 knots mark. It will be noiser I would think (although the sound of a 225 does apeal to me more than the gentle hum of a suzi 140) and will drink more fuel (and oil of course).

Basically I'm trying to weigh up what is better
Suzi for quiteness and economy
Opti for performance and speed.

Do people think that there would be a dramatic increase in fuel used at say 30 knots with the Opti as opposed to the suzi?

I don't think the fuel consumption will be very different at 30knts.

The Opti would be running well down its rev range and the Suzi near the top of its rev range.

The Opti then gives the option to tear around when you want to as well.

I honestly think that if you go with the smaller engine you'll regret it very soon. 7M is quite big for 140HP

Well, if in that case go with the opti, it will put a grin on your face every time you use it!

Yes, with talk of this and trailers. Tim must be planning something, although I don't think even he knows what it is .

I think he's been drinking Black Death though his eye again

With all this talk of outboards and trailers, I reckon he's found a dirt cheap hull somewhere he does not want to let on about til he has it in the bag

Can't say as i blame him either!

Engine Choice

I have a Suzuki DF140 on my 6.3m RIB and it is good for economical cruising. However, having lived with it for 2 seasons I would now prefer the new DF150 or DF175 for more fun!!!

Having just come ashore from playing in a new Humber 9.5m with two DF200s on the back I was surprised how economical they were, especially at 4500rpm, whilst at the same time providing a huge amount of the 'fun' stuff!

Consequently, I would suggest you look at Suzuki's DF 150/DF175, or if you want more fun their DF200/DF225. They all provide good economy at quite reasonable all-up weights. Finally, you will always want bigger so why not get it right at the beginning !!!

Of course the 140 is okay. Its just a case of if you want/can afford/need the larger cc's/hp to kick in. The 140 is a good engine but the 150/175 has got to be better. Its bigger and cost more.
Personally I have seen modern/new 90 HP motors on the back of 6 meter boats and they have been okay. If you have got the money splash the cash. If not go for the smaller motor.
