GT 185 - 3.0L vs 4.3L - My opinion
« on: February 23, 2010, 05:21:06 PM »
I have read a few threads regarding the GT 185 and the 4.3L.  Just want to throw my opinion in the ring to maybe help someone with their decision.  

I have a GT 185 with a 3.0L (135hp) that of course is carbureted.   We chose this motor mainly because of the amount of people we have in the family (3) and the cost (fuel and initial cost).  If there was one thing I would change, it would be to upgrade to the 4.3L.

There are only three people in my family (About 500lbs) and at WOT we’re only at 34mph.  It pulls a tube very well and we’ll find out about a skier this year.  The issue surfaces when I put additional people in the boat.  Still under the weight limit of the boat, but it seems not under the limit of the motor.  Most of the time my wife or I stay at the dock while the other takes out our guests.

The salesperson told me the boat would do about 45 – 49 mph with 4 adults in the boat.  He steered me away from the 4.3L.  Should have gone with my gut.  Additionally, my wife can’t start it; she keeps flooding out the carburetor.

I love my boat and it is built very well.  But lesson learned.  I agree with everyone else, go the 4.3L way.

GT 185 - 3.0L vs 4.3L - My opinion
« Reply #1 on: February 25, 2010, 01:35:26 PM »
I would have thought the 135hp 3.0L would have pushed this boat a little faster. I was figuring 40- 45MPH range.  Maybe it has to do with the amount of people on the boat. I would believe it would be slowed down more dramatically than the 4.3L with added weight.

Anyway, (my opinion) / rule of thumb has been the following: Always buy the boat with the biggest motor sold in the boat. 1) if you are worried about gas prices you really shouldn't get a boat. No matter what, a boat isn't very reasonable with gas. 2) resale will always be much easier / better resale price if the boat has the top engine.  3) even if you don't normally go that fast on the water I have always believed it's better to have it and not need / use it than to not have it and be wanting it.

Obviously, if I can't afford the biggest motor sold in the boat I want, I would rather buy it with the smaller motor so I have a boat and can enjoy being out on the water.

I have not been in a boat with the 4.3. My only experience was when I tested a 2007 GT185 w/ a 3.0. It was adequate with myself and the salesman in the boat, but I could tell a loaded boat would struggle pulling a wakeboarder or skier. I'm glad to hear your opinions since I chose the 4.3 option.

I will say the 4.3 L is quite fast, and accelarates out the hole quickly.
I do agree with specialk, point by point. I almost bought the 3.0L and the sales guy told me it would be enough for what I wanted it to do. But my gut told me I would not be happy with a smaller engine.
I also have a seadoo 2 seater 110 HP, the sucker is fast for its size, so I knew what 110 HP could do, so 135 HP is close.
I had both machines doing almost 80 km, and the boat being heavier with 3 onboard over took the sea doo.
My point , if you are buying a boat, any size engine and you are worried about gas prices and consumption, don't buy one cause it's not like a car, you wont get 500 km on a full tank of gas. I learned this by owning a sea doo pwc, they all are expensive hobbies.
Go with the 4.3L

Thanks for the replies.  I'm not worried about the gas prices, just wanted to be as frugal as I could.  The fun we get out of boating far surpases any cost.

I'm still very happy with my boat as it does what I need it to do.  Just wanted to comment.

Today with 5 people in the boat, I was able to appreciate the 4.3l. Granted we are still breaking it in so I haven't done any hammer down hole shots. BTW, the TKS 4.3l actually works. Turn the key and it starts even after sitting overnight. I like that.

I had a 2009 GT 185 w/135 hp and was very unhappay as it would not pull an adult skiier out of the water easily.  I traded it for the 4.3l engine and it is a world of difference.  Go for the bigger engine.

I had the 2008 MX 175 with the 4.3L GL-I now have the 2011 GT 205 with the same motor. I loved the 4.3 in my 175 but I wish I had found a GT with at least the 4.3 Gxi.....The 3.0L in my opinion just doesn't let your Glastron act like a Glastron...running a 13.7/8 by 23 stainless my 205 does about 51-52 and my 175 did like 55-56....lots of speed from a 190....

I recently purchased a gt185 with the 3.0L MPI, I got a very good deal on the boat so I did not have the choice for an alternate motor. After reading reviews everyone downplays the power, but I have had the boat up to 45 mph with 4 adults in the vessel. Still breaking in the motor, so I have not tried to push it much more, but I would bet that with fewer people in the boat, less fuel in the tank, and the trim adjusted just right this boat/motor combination could do 50 mph. I do believe there is a vast difference in the dynamic of the TKS motor vs the MPI motor.

I can definitely understand this motor being underpowered if pulling a skier, but for my needs I am more than happy. Plus a tank of gas lasts me a long time.
