View Full Version : Prostar 197 5.7 or 6.0

I am in the process of ordering a prostar 197 the difference here is about 3500.00 from the 5.7 to the 6.0. I have been told I wouldn't really notice the difference between the two so was wondering if it is worth the extra bucks .i was thinking if that's the case maybe I should spend the extra $$$$ and add saltwater series with heat exchanger.

6.0 For Sure

depends on what are you doing with the boat.
I have a prostar 195 with the 5.7, we are 70% skiers, 20% barefooters and 10% boaters.
my sons and I slalomn, they are very good and weigh 200lbs, pull has NEVER been an issue
same goes for the footing, no issues with top end
so if that fits your plans why pay extra for the 6.0 upfront and forever at the gas pumps?
just my 2 cents

I have a 6.0L in my '03 197. 99% slalom use. Don't need it. A 5.7L would be more than enough in my opinion. Use the money for other stuff, unless you think a couple extra mph and a slightly quicker 0-34 time is worth $3500. :twocents:

That said, the 6.0L is a stout motor and I'm happy with it. :)

I thought bigger was always better...

I'd say 5.7 for a prostar. Its more than enough for a small slalom boat. Plus it is probably a little lighter than the 6.0. I'd sink the extra money into more beneficial options.

IMO I agree, especial if the money difference is no problem. I have skied behind both and can say I did not feel any tremendous difference on the end of the rope. I do not know in the 2012 models if the reduced transmission (PowerSlot?) is a option anymore? But if it is, I would price the difference between the upgraded engine and transmissions and go with the 5.7 with the reduced transmission. Either way congrats on the new boat, you lucky dog.:)

By the looks of the current used boat market, and based on what has transpired with recent sales, I'd say that you will get back what you paid (and more) for the bigger engine when you want to sell or trade the boat in. Too much power isn't a bad thing with these boats.

I will also say that the difference in fuel consumption is negligible under normal operation. I have two friends with X-15's, and the LY6 uses less fuel than the MCX. My other buddies X-45 with the LY6 uses more fuel than my 45 with the L18. More power moves the boat easier, lower RPM = less fuel usage, IMO.

Do you barefoot? If so, how fast is the boat with a 350? How much faster is the 6.0L?

^^These are the answers you need go get in order to make an informed decision.^^

If you dont barefoot and dont care about top speed, then you would be unlikely to appreciate the larger motor. They make very similar power below 3,000 RPM. North of that, the 6.0L pulls harder and longer. For a slalom boat, the 350 does great. It falls a few mph short in a barefoot boat with a slow hull though, IMHO.

I have a 214 with a powerslot 5.7 (Ilmor) and still never use WOT pulling up a slalom skier. It seems their arms give up far easier than my powertrain. With a ton of additional ballast, the difference becomes noticeable, but if this is primarily a slalom boat I couldn't justify the difference.

I may be wrong on this but I think the 6.0 requires a larger engine cover which will take up more space. Just another consideration.

Get a 6.0L every year and the fuel is better or the same as 5.7. My new TT boat uses 4.5-5.0 GPH right now still only 10 hrs. will only get even better with time. Also resale on a 6.0 is better because there are that many around. IMHO:D FYI the motor boxes are the same size they were different, but not any more to much money to build 2 separate boxes.
