Well just got some bad news from my mechanic. Looks like I have a couple bad cylinders on one of my Yamaha 200's. Looks like I'm going to be forced to repower now. Told the shop to work me up a price for new two stokes and they told me that all he can sell me here in California is Four strokes. I guess CA passed a new req that says all motors must meet a Three Star rating. Four strokes are the only motors that meet that rating. From what I have read here on the site is that the Four stokes are adding too much weight. I have the bracket model 1991 Dolphin. What do you think? If I just tried to sell the boat as is now what do you think it is worth? Not the news I wanted to hear!

They must be a Yamaha dealer. E-Tecs are 3 star rated 2 strokes. Does the law prohibit you from buying used HPDI's? Some 4 strokes have been posted as being too heavy. The 175 Zukes, and 200 4 cyl Verados are both similar in weight to the 2 strokes. Ones that I'd stay away from (from a weight standpoint) are the Hondas and 6 cyl. Verados, both are well over 600#. If you already have Yamaha controls, I'd get a set of used HPDI's (you'll probably need some adaptors to use the existing controls which you Yami dealer can get).

Verify the three star carb requirement with officials, he may mean conventional 2 strokes since he wants to sell you what he sells, 4 strokes.

I can see Calif not allowing conventional 2 strokes, but not anything with a 2 or better star Carb rating.

If you are not planning to keep the boat many years, get the powerhead replaced. We're talking $30-35K for repower.

After that, be it 2 or 4 stroke, let the debate begin again -

It's not worth doing the powerhead on 1991 engines, it'll be a never ending money pit. If the money is tight go used.

dont repower

Having just bought a 1993 Sailfish I would not repower a pre seav2 hull. In my opinion, unless you plan on keeping the boat for a LONG time, it is throwing good money after bad. There just is a big price difference between pre seav2 hulls and post, and the post seav2s are excellent choices for repowers, but the many people who are trying to sell their older pre seav2 models that have been repowered are not getting what they want.

The SeaV2 hull seems to be more of a factor in the smaller boats. With the Sailfish people say there isn't a much of a difference.

Whether or not it makes a big difference in terms of ride quality, I don't think is the issue. I can tell you it makes a huge difference in the market for these boats. That's why my advice would be to not repower one of these pre-seav2 hulls unless I was planning to keep it for many, many years. It's just my opinion, take it for what it's worth...

It appears to be difficult finding used older 2 strokes even though plenty of repowerings going on. I wonder if the 4 stroke manuf. associations are buying these from dealers at a nominal cost and detroying them (?)

I had to sell my motors on the side, got several grand for them, sight unseen, the dealer looked at me like I had two heads when I asked what he could do.

I suggest to place an add in GG for sale/buy section, and other places, to invite repowering guys to sell you their motor. Nothing wrong with a lot of motors being sold just for the sake of getting 2 more strokes over 2 strokes. Start the add with "Thinking or repowering?"

Bob, i know of a few 2 strokers that went to Europe to be sold there. The 4 strokes in Greece are very very expensive, so the used 2 stroke alternative is great. No EPA laws there either.

It wouldn't surprise me, hard to think the repowering dealers are passing up a chance to make easy money reselling used 2 stroke motors, especially to blown motor customers, at 4X the trade in, at least. And I doubt the motors are going into their trash bins out back.

There was nothing wrong with my '92 motors, the guy that bought both didn't even ask me to start them up in driveway on stern of boat noir compression test, never mind sea trial. He only needed one motor, but at the price couldn't pass up the second, he said he was going to sell it. All the same to me, I just wanted them gone.

Shop around a little bit. I don't think you're stuck with 3 star ratings if you're buying used. I'm not 100% sure but I think that only applies to dealers selling new motors.

I saw this posted on another message board. He's located in Santa Barbara. Not affiliated in any way, just thought it might be a good deal for you or someone else.

Thanks for all the post. Yes the boat is at the Yamaha dealer and it is the Yamaha 2 strokes that don't meet 3 star. Not sure if the dealer can sell used motors that do not meet 3 star. E Tec would be an option, as one post mentioned they meet 3 star rating. I just can't belly up to the bar for new. I did find two pair of used Yamaha 200's. First pair is 1991 with 900 hrs. all controls and gages $6500. This is basically what I have now.
Second pair is 2003 Yamaha 200 HPDI with 900 hrs. One just got new power head. asking $10,000. What are your thoughts?

Way too much for the '91s and I don't trust motors that have had powerheads replaced... Those '91s should be closer to $3000 (maybe less)...especially if they still have the steel shift shafts that rust out and cost big $$$ to replace.

I'd be all over a pair of 200hpdi engines if I were you (assuming you can find some that are decently priced with moderate use). I repowered our gulfstream with hpdi last summer. There are no restrictions that I'm aware of regarding repowering used in CA. I didn't ask around however so who knows.

I found our engine at ARG Marine in FL and had it shipped to my mechanic. http://www.argmarine.com/

I do agree with the comments regarding the pre SV2 hulls and repower however. I don't know that you'll get your money back if you try and sell that hull with 2 strokes that you buy. If you dump money into a repower you should plan on keeping the boat for awhile.

The one selling the '91's is smoking something, $3000 tops if it was in fresh water or maybe $2600 as long as the shift rods look OK (with functioning controls). Don't be afraid of the hours on older motors, they suck up more oil but that's a good thing for longevity (as long as you decarb). If the HPDI has a new power head (from Yamaha) not rebuilt, offer around $9K after they pass a compression test. From what people have said, I would trust a rebuilt powerhead as far as I can throw it. Also get a download from the HDPI CPU's, it'll tell you a lot of info.

If you do go the HPDI route, change EVERYTHING before you run them (all filters, water + fuel pumps, thermostats, O2 sensors...). People don't take care of the O2 sensors, the engine runs lean then BOOM. Don't let the dealer BS you, your controls will work but you will need adaptors.
