Your 150's still nearly as heavy as my 200

The Opti 135, 150, 175 are all the same engine (therefore same weight).

I'd of had a 175 if it wern't literaly thousands more (Richard knows what i mean ).

I did my homework on this, and apparently the Opti has the potnetial to be more efficient that a 4-S, but i've, as yet, no evidence to back that up. You need to ignore the cost of oil in this argument i beleive.

I'd get an Opti, performance and economy if you're sensiable with the throttle.

And? There are very few 7.5 ribs out there with 200's that can outrun me with my heavy 150 engine!

My point is that on the basis of seeing one service bill for an Opti you tell the guy not to buy one of the best engines out there and not even knowing the model range you still advise him not to do it.

The cost of a service is usually 135 pounds plus parts, the dealers tend to whack the parts in at full retail price and that bumps up the bill. If you want to keep down provide your own impellors and filters etc.

The Opti 200 and 225 are identical engines I think the 150 has a smaller bore.

I guess if he does buy an Opti he can always save money by running it on Ordinary 2 stroke oil

cheers
Stuart

Daniel.

you can always buy a 150 and drop a 175 chip in, when it's out of warranty of course

Wave is right, go for an opti, they ae excellent. The 200 and 225 are 3ltr blocks and the 135 and 150 is 2.5ltr. They are all bloody solid.

The new 115 Opti is a 3 cylinder rather than the v6 which all the others are so the weight is much less, I don't know much about it but bet it is bloody good.

Just consider this guys, the car industry has been developing petrol engines for 100 years now and has not bothered at all with 2 strokes. If they are so good then why does the car industy continue to spend billions of 's on 4-strokes?

simple - 'cos 2-stroke cars are banned.

There were a few very successful 2-stroke cars. Most noteable was the Saab (errr, can't remember the model - think it was the 93? aka the bullnose saab) and most lamentable (in UK) was the Wartburg Knight, or (in Eastern Europe) the Trabant.

Uh Oh! I've upset the Optimax evangelist...

Stu - I never "advised the guy not to buy one of the best engines out there", but gave some objective input on the overall cost of running different outboard types. You've put 500hrs onto an engine which has performed faultlessly for you, which is an excellent recommendation whichever way you look at it, but is that considered exceptional or normal from modern machinery? And remember that the original question was about running costs - so it wouldn't be realistic to ignore the cost of two-stroke oil.

Filling the 2-stroke oil is one of my hated jobs at the moment and I would recommend that anyone rigging a 2-stroke makes sure that the reservoir is very easily accessible.

Now dont' get me wrong, I also think that the Opti is a great engine - I spent lots of hours driving a very similar Scorpion to yours last season, Stuart. The acceleration was exciting, and they certainly sound the business. I just reckon that overall setup and rigging of the boat is as important as pure grunt.

I could be a Yamaha evangelist, and lots of people are, but I have only put about 70hours on mine in which time I EXPECT it to perform faultlessly. So I'll save that for later! And the Yam. 150hpdi is even heavier than any engine we've talked about in this thread, so not a good recommendation in my opinion.
