Zodiac Pro 15 Man. 150 Optimax or 150 Carb Vmax

The Optimax seems to be a perfectly good engine and lots of people seem to swear by them. The 150 Vmax Carb on the other hand is lighter and has the Vmax feature. I heard you can get a sunstantial kick in hp in the upper end with this engine. The Yamaha 150 Vmax Carb is actually lighter than even the 2-stroke 150 Yamaha. The 150 Vmax Carb only comes in 150hp and is lighter than the 150 Vmax HPDI. Does anyone have any experience with this Vmax 150 Carb? People seem to like the 2.7l Vmax 150 HPDI. Any major differences in fuel ecomomy between the 150 opti, 150 Vmax Carb, and 150 Vmax HPDI? One more thought, does the HPDI version increase the Vmax effect?


To top it all off we are planning to boat from Chicago to New York through the Great Lakes. Is it feasible to get a 2nd hand Honda 90 4 stroke for the trip, sell it afterwards and switch to the 150 Vmax Carb. I am just thinking that I don't want to drill extra holes in the transom.

I see that weight is are major issue for you. Then don't place a second 90 on the transom. Just take care of your engine and buy a Vhf for safety.

HPDI and Optimax is about the same system and it saves a lot of fuel compared with the carburated ones. Especialy on long trips it's sometimes important to save fuel.
Leave the carburated Vmax if you want to save money on fuel.

Optimax has a Smartcraft system wich comes in very handy on long trips because it's fuelmanagment.

All weights are about the same.

Personaly I would go for Mercury.

Thanks for the info Danny. One more for the Optimax. Anyone else prefer the Vmax out there?

Re: Vmax outboard

Just to weigh in with my opinion.. If you are buying a larger rib chances are you are going to need a 25 inch shaft length and that is not available for the Vmax motor, 20 inch shaft only. I believe Yamaha markets this motor towards the Bass boat- ski boat market in the U.S. You could use a jack plate to get around the shaft length issue but it would probably be too short. I have owned and ran two different carburated 150 hp. Yamaha outboards and they both gave me great dependability, The hpdi is available only in the 200- 300 hp models in the states unless they have recently changed that. I might add that these motors have all started at the touch of a key once warmed up, I have never owned any other outboard that started as easily as a Yamaha, I also have never had a Yamaha stall on me at low speeds or after startup.
Understand that I personally have no loyalty to any particular brand, these are just my personal experiences, I also owned a 1994 Nautica with a 1991 Yamaha outboard I bought used, I used that boat extensively for 4 years and sold it to a friend who still has it, the only thing that has ever been done to that motor is a spark plug change, Twice! Mind you the motor was running fine, the plugs were changed only for maintenance. That motor probably has 1500 hours on it. One of the 150 hp. engines I bought used for a song and a dance ($650) from a dealer here in Ohio who dumped it because it was a takeoff from a police boat. The motor was 13 years old and had 3400 hours (thats right 3400 HUNDRED!) they were afraid it wasn't going to run much longer, the motor had good compression, I ran it for four years, another 500- 600 hours and recently sold it and the boat it was on, still running fine! In this same time period a good friend of mine bought a couple of Merc 115 Saltwater series engines brand new and within 3 months had to replace a power head on one of them. Now Mercury took care of it under warranty but the boat was in the shop for 2 1/2 weeks during July, I was out pounding around with my "worn out" Yamaha. I have owned Mercs, Evinrudes and Yamahas, I do not think you can beat the dependability of Yamhas versus Mercury. I do not have an opinion on Honda or Suzuki as I have never owned one, although I have heard good reports from other owners. Don't even mention Bombardier-Evinrude, they have no track record with the new motor. In any case you will probably have better access to parts and acessories from Yamaha and Mercury as they are the two major players right now. You might also look for a New old stock motor from dealers nearby, It is possible one might be available, they are from time to time around here. You might also call Lentine Marine in Florida, they are one of the biggest repower specialists in Florida, possibly the country (772)221-3777 I like to buy motors out of Florida, they have better pricing than in the Great lakes. Also, a 150 will push a 22 just fine, you won't need a bigger engine, and as to buying a 4 stroke honda now and repowering later with a 150, I believe the transom bolt pattern will most likely be the same, call Honda and check with them. Hope this is of some help.

You should check the price of both engines. If i remember well the price for a carb engine is 20 % lower than a HDPI. So if you don't boat a lot, that VMax carb could be a good deal. But if you plan to use it a lot, fuel savings might be an issue!

also consider resale value and what others might prefer as an engine on the back, people will prefer opti/etec/hpdi and 4 stroke to an old style carbed two stroke.
