I am lost. I am a first time pontoon owner and bought a 2001 22' suntracker party barge. It has a 9.9 Mercury Big foot and I am looking to go bigger. I have found a rebuilt 2002 60 hp Big Foot EFI and also a 50 and 75 hp Mercury 4 stroke but not EFI or big foot both are 2010. They are all similar in price but the 60 is the cheapest by about a thousand dollars. Is the 60 the best bet being a big foot and efi? The other two are not big foot or efi. I am not a speed demon and the pontoon may be loaded at times, but not that often. I am just trying to make the best decision knowing that I need the least amount of hassels out of a motor and I don't want to feel like I am standing still at full throttle. Any suggestions?

Are you saying that you can actually MOVE that 22 footer with a 9.9hp??? Upstream? :)

The Big Foot is designed for pontoon boats due to the strange double wake. If the 60hp has a fresh rebuild and especially a warranty, then I think that would be your best bet. Especially for $1000 less.

Welcome to iboats.

With the EFI engine you have a computer involved and injectors which is far more complicated than a carbbed engine and normally the more complex you make something the more expensive it is to fix when it breaks so I personnaly would go with the carbbed engine since I am able to actually work on that, efi not so much.

with all the engine being newer you are probably fine with any of them but the Bigfoot is made for a pontoon so that is probably the best of both worlds.

I have a 60 efi Bigfoot on my toon and am very happy with it. I find it quiet and extremely good on gas. The difference in power between it and the 75 would be negligable. Is the 75 a long shaft, because it needs to be?

If those three are your only choices, then it's a no brainer. You need the big foot.

Re: Mercury Motor confusion for first time pontoon owner

All motors are long shaft. My biggest concern is that I need as little hassle out of the motors as possible. I am concerned because I have asked a few dealers and they push me towards the EFI. I may only use the boat every couple weeks and I am wondering if the EFI will hold up better to sitting and then being used. Also the 60HP Merc was rebuilt and the guy stated that the previous owner let it sit to long and then tried to run it full throttle. He stated that the oil did not get distributed throughout the motor properly and it burnt up. So.... I am lost. I found another 90HP mec with 1 year warranty, but it is not bigfoot or EFI. I am running in circles. M gut tells me that the big foot in a must for my pontoon but EFI/Carb I am not sure. Again my gut feels like EFI may be less hassle for me. Are th newer engines that much better comparing a 2002 to a 2010?

Any thoughts? Thanks so far for the input this is my first forum question ever!

Re: Mercury Motor confusion for first time pontoon owner

I would exclude the 60 because of the potential for other additional problems. Of the motors you have listed, I would go with the 90 because of the 1 year warranty and because I think you will like the extra power even if you seldom use it. It's hard to beat a two-stroke carbed motor. The carbs are cheap to rebuild and is usually only required every 10 years or so unless the motor set for long periods of time without proper storage applications. IMHO, I certainly wouldn't shy away from a carbed motor if the other criteria meets your needs.

IMHO, carbs are great if you plan on doing your own repairs and you have no training on fuel injection. Any backyard mechanic is having to get used to efi as all vehicles made now use fuel injection. With efi, there is more computer control and sensors. All my previous motors were carbed, but I do like the benefits of fuel injection. I can run 8 hours at 3/4 throttle and get home without refuelling the 70 litre(18.5 US gallon) tank. In my opinion, efi is just as reliable, and maybe more reliable, than carbs. That being said, I'd love to have a 90 on mine.If the money was close between a 2002 60 Bigfoot EFI and a 2009 90 with carbs, and both were 4 strokes, I'd take the 90. As to sitting for a long time, with efi, the motor had never failed to start at the first turn of the key, even after sitting all winter. You failed to mention if you are talking about 2 stroke or 4 stroke.
By the way, there is no 90 Bigfoot. The 60 Bigfoot have the same gearing as the 75 and 90, so that isn't an issue.

The "Big Foot" engines (only available in 40 thru 60HP) get the Mid size gear case which is the case from the 75 thru 115Hp engines.

All motors are four stroke. The 90 is not a big foot which is the only reason I have second guessed picking this motor. The only big foot is the 60. I was not sure if the extra 30hp would really make that much difference. Also I am not a back yard mechanic so that is why I am so concerned with the hassle, I have no intentions of working on the motors myself. Its not that I am useless with a wrench I just have so many irons in the fire that time is more important than money. Within reason... Crabs worry me because I have had multiple problems with mowers, weed eaters, etc because I do not run them that often. Boat motors are a new breed for me. I guess if the 90 is the front runner am I going to be so lost without it being a bigfoot or EFI? It i exactly one thousand dollars more than the rebuilt 60 bigfoot.

As previously stated, Bigfoot is not an issue. The 90 long shaft is the proper model for a pontoon. Hands down, it would be my pick. Also, I was under the impression that all 75-115 hp 4 strokes from Mercury were EFI only after 2007. I could be wrong on this point but worth checking.
