Used Optimax vs Yamaha 150hp.

Question:

If you were looking to buy a rib and there were two boats available which ticked the boxes, which engine?

Yamaha four stroke or Optimax??? Both near enough the same hours.

How much premium would you pay for your choice???


Which is more economical?

Thanks!

My 200 Opti gives 1 mile to 1 litre average which seems to be true ish for most larger engines(150-250 ish), but you'd have to ask a Yamaha owner to be sure of their figures

I'd be more interested in the age of the motor its life and if it has any warrantee left or will the seller put any warrantee on it?

Both around five years with 150 hours. No warranty. Great cosmetic condition and service history.

Yes, that's what I expected with fuel.

Thanks.

I operated a 150 four stroke Yamaha for a while and when idling or at low revs was definitely cheaper to run than Opti when working alongside them, but when we were all operating under throttle there was very little difference and the fuel bills over Cowes week were almost the same but we had no oil to add in also I know the Yam is very quiet. Hope this helps

I'd think about what I would be doing . For me to get to the sea is a 5- 10 minutes at low revs. My 4/s Yam ( although only a 50) doesn't even notice it , but the opti ( 200) really wants to run at more than tickover and can sound like it misses every so often.

I've noticed my opti also realy doesn't like anything less than a 100% charged battery to start it. But again I get around the 1l / 1m in petrol - slightly more if I cruise around 25knts and dont push on - but I dont do that often ! Not sure about the bigger Yams.I think the optis only really comes alive at higher revs !

There wont be a great deal of difference in the economy dept. There will be a great deal of difference in the noise dept., especially at low speeds. I reckon I'd rather own an older Opti than an older Yam in terms of things going pop. My 8yo Opti never missed a beat, my neighbours 115 Yam 4st quite likes gearbox seals.

There's lots going on under the hood of both those motors, but if you end up having to look for used parts, there's a lot more chance of sourcing them for the Opti.
When buying new, I had a similar dilemma, which was easily resolved as the 4-stroke Yam F150 would have cost around 2500 more than the 150 Opti, so I bought the Opti. It's a great motor when it's singing, but a PITA when pootling around at idle - very noisy, compared to a 4-stroke.
Suppose it depends on what you'll be using the boat for.

What boats are they on?

Both on Ribeye 6.5's.

We keep the boat on the Hamble and cruise the Solent. We did 100 hours on the engine on the old boat from May to August, so I guess we use the boat a fair amount.

Thanks for all the comments so far, really appreciated. They are tending to echo what I was thinking.
