PCM 5.0 Pro Sport

[jc]

I am looking for opinions on the 5.0L 275hp pro sport engine. I found a 03' 206 with this engine for a good deal but have never ran one, only 5.8/5.7's. How is the power? We mostly course ski and have a little guy, 7, who skis and kneeboards and I ski at 36mph into 35off. Does it have enough jam? Is the fuel economy that much better?
Thanks for your help.

It's fairly rare to find a 5.0, as it was the base engine and not sought after. It was more or less available as a low-cost option for customers wanting to cut all of the costs they could to get into a Nautique. I'm certain you are seeing first hand the low resale value of these units, as the deal must appear pretty good when compared to the 206 market place. With that said, take a pull behind it and make a judgement call. Will it pull you at 36, absolutely. You won't see any additional fuel economy, as it'll work a little harder to do the same job of the Excal. I've skiied behind a 5.0 numerous times, and foolishly thought I'd be able to man-handle it a little in the course. I couldn't get any deeper than behind my Excal. If you like it after a test drive, you always have the 5.0 as leverage in your offer. Just be prepared for the same leverage against you if and when you decide to sell it.

Just to point out something that is a misconception. givin that prop size and transmission ratio is constant the hp needs to pull a given skier thru the course remains the same whether the engine has 200 hp or 500 hp. Another words if a given skier utilizes 160 hp to run 35 off at 36 mph then it will take 160hp if the motor has 200 or 500 hp.

The 305ci/5.0 liter Pro sport engine has a lot of low end torque and really does a nice job for general skiing purposes. dont be afraid of the motor as it will do all that you need it to do and you will be suprised at it's performance. Just dont try and pull big 35 mph jumping, thats when the bigger hp needs come into play.

As I remember, my buddy's boat would run at a few higher revs to achieve the same speed? The hp required to pull a given skier makes sense, but the power curve along the rpm's could be a little different? In the end, a good point, it's a strong engine that's fully capable - just don't buy it hoping to save on gas:-)

5.0

Thanks guy's, she would be just for slalom skiing, no jumping.
Teamseal, would the top end be comparable as well? Say 40-45ish. We do some footing as well. What prop size/ make would you recommend for this engine based primarily for course skiing?
Also, would the Zero off conversion kit work on this engine? It does have digital throttle control.

I was wondering if you would be doing footing. If I remember right, there was a guy complaining about the performance of a 5.0 when used for footing. I may be wrong, but it might be something to consider. That may not be nough omph for footing to be adequate. Keep in mind this is just what I have heard, I have no experience with footing or those engines.

ZO won't work on an '03 - only certain '07's forward.

If I remember correctly the 5.0 was a throttle body and not a multiport like the Excalibur, ZO could be done but cost about 3/4 the price of repowering to a current E-controlled motor.
If you are light and their is not a tower on the boat I am sure you could Barefoot with the 5.0 should pull at about 40-41 mph but then you might want to save the barefooting to being behind someone else's that has the Cubic inches.

The 5.0 is very hot rod-able so to speak, their are numerous products in the hot rod market that can boost the HP of the little motor to up over 300hp for less than $1K. Winter project!

Thanks again guy's, lot's of info to consider. I will see what kind of money I can get it for and go from there, might be worth it. I like the idea of ''modding'' that 5.0 and turning it into a sleeper!
This site is so great!

Actually, teamseal has been retrofitting ZO to 02+ 330 Excalibur engines. It's more involved than just flashing the ECM or replacing the ecm in an 07, but certainly doable.

Jody, are you sure? I know MC had an injected 5.0, but I thought CC used a carb'd 5.0? ICBW. BKH

The current version of the PCM Pro Sports 5.0 has multiport fuel injection. Not sure if it uses the delphi based MEFI like the Excalibur's, though.

Efi?

Got a call in to PCM to see if the 5.0 uses the same EFI system as the 330 Excal. If so I should be able to use the zero off conversion kit I think. I will keep you posted.

[teamseal]

So many boats, so many engines! It truly is hard to remember who, what and how. I did look up the motor that was available in 03 and it does look like it was a Multi port like the Excalibur. If indeed that is the case then yes It could be converted to e-control DBw and utilize the ZO system. the unknowns are if the 5.7 E-control Calibration would run the 5.0 motor without causing problems.

[2gofaster]

Jody, something in my brain says that I was told you could order a base SE196 in 09 with the 5.0 and ZO. So there may in fact be a 5.0 calibration for this app.
