150 VMax or 150 Merc EFI

17 posts in this topic

what would be a better option. A 150 Vmax carbed or a 150 Merc EFI? I can get either of these motors for the same price but am unsure on which one to pick. I know that the merc is being discontinued this year sometime. I can also upgrade to a optimax for 2grand but not sure if its justifiable.

I don't know about the V-Max, but I've heard the EFI is a bit of a gas hog. Might be worth the extra $$ for the Opti due to it being able to save you on gas.

I would go EFI over carbed, but if the Opti is within your budget that would be the better motor by far.

Im a big Yammy fan but I believe the EFI would be a better motor with all things being equal. That Vmax is one nice motor though. I know a few guys with the 150 Vmax and I have never heard anything bad from them. My buddy had a 225 Vmax I think it was and that baby moved out.

If you can swing the additional cost for the Optimax I'd go for it.

If not, it's kind of a tossup... the EFI will get your better Fuel Mileage, but the Carb'd VMAX is a bit more dependable in my opinion, with fuel mileage worse than the EFI.

I also say opti if you can swing it. Fuel economy will be much better, but on the downside oil is over $40 a gallon. If you like to do your own winterizing and maintenance then go for the Vmax. (look under the hood and try to change a plug on the opti and you'll get the idea). I really liked my 150 Vmax, and I didn't have a problem with it except a throttle cable that wore out in 8 yrs of ownership. It was ok on fuel as long as you didn't run it at W.O.T., With the hammer down, you can watch the fuel guage drop. Lots of guys in my local bass club had similar experience in reliablility, but some of them had problems with ethanol gas eating up their fuel pumps. I always ran premium non-oxygenated fuel in mine.

Thanks for all the input guys. Now the plans have changed and the boat I want is rigged with a vmax (carbed). I do have the option swapping for the HPDI for 1500 bucks. I can also put a opti or etech on for alot more money because of the extra labor involved is switching the cables, controls, etc. Is the HPDI worth the 1500 over the carbed or should I bite the bullet and spend the 2500 for the opti?

I would go with the HPDI, it's a great motor and a DFI just like the Opti and E-Tec. IMO there's no reason to spend the extra money to rerig for the Merc or Rude .... but I would go HPDI over carbed.

I'm looking at new rigs right now too. If it was me I would pay the 1500 for HPDI, even if everything was equal I would take the HPDI over the Opti (in full disclosure I've never owned an HPDI).

I have an HPDI now and my last boat had a yammi F-115. The HPDI is as quiet and clean as the four stroke was in all respects. Go for the HPDI, it burns clean, starts right up, and runs great...you won't regret it.

    • Good question, why didn't they find any more?  Did those two infected deer parachute in?  Were they dropped by a helicopter?  I find it fascinating they could get as far as Lanesboro and they only find two out of thousands.  Like I said, they're bad at conspiracy.    Policing the borders?  How about a billboard, a radio ad, or a twitter campaign?  How about having the highway patrol pull over anyone with hooves or antlers sticking outta their truck box or laying on a flatbed coming across the border on the interstate?    My wealth and land ownership shouldn't disqualify me from questioning the DNR.  It used to be a staple of a free country to question your government.  Somehow now it's more important to kneel before the all knowing DNR and take whatever they want to shove in our mouths?  If this is real science and a real mitigation effort, let's have a discussion about it.  If the DNR wants to stop this spread, why are they not welcoming with open arms feedback like mine when it comes to import enforcement, and an effective PR campaign?  Cause guess what fella, lots of deer got hauled home from all kinds of places infected with CWD by uninformed folks that are going to cut up those critters and throw the brains and spinal cords out in the woods at home.    So yeah, this is either a giant hoax, or the DNR has no idea what the hell they're doing. 
    • I just checked on the fans that I bought, there 4.7 inchs sq and 1.25 thick. I thought they were 5 inch thick but I was wrong. They are 110v and I think I will put one inside on the bottom plate and see how it works. And I like where you have your fishingstar.

    • Yea I had that idea too 
    • I saw three or four huts in the little wet area in the lake vadnais area just off country road F.   But they would probably get upset if you set traps there...    right next to the new path that goes south along the east side of the lake. 
    • In the olden days, pigs were fed garbage.  Trichinosis was a problem.  Then laws were passed so any garbage fed to pigs had to be cooked first.  Problem went away.   According to CDC there hasn't been a case of trichinosis except from eating wild game like bear meat for many years.  
    • From a quick google search it looks like waveinn.com or the bay of e might be your best bets, if you don't want to buy from shimano.
    • Does anyone know of a place you can get spare Shimano Sedona spools?? I run braid in the summer and don't want to run it on the ice.
