    Arrow Buying 2003 MSX140 - what to look at, what to check?

    Well, it seems a decision has been made, and I am now buying at least one Polaris MSX140.

    We went back and forth re: carbs vs. Fitch 2-stroke vs. injected 4-stroke, or shopping some other brand - decided to go with Polaris 2-stroke injected.

    Genesis i vs. Virage TXi vs. MSX140 - picked MSX140, primarily on the ergonomics aspects.

    2004 MSX140's seem to be thin on the ground around here, so 2003 MSX140 it will be (at least four to choose from right now). Seller reported hours are; 39, 46, 88, 92 hours.

    So, what potential issues should I be looking for, and checking, when I go to buy an MSX140?

    I can do a compression check fairly easily, I think (note to self, check downloaded manual re: spark plug removal procedure). What compression numbers should I see?

    I will carefully look over the hull top and bottom. Any known hull crack risk areas, potential loose fasteners, etc?

    I may or may not have a chance to get it on the water before I need to decide. With an injected motor, what can I check on the trailer?

    Do I absolutely need to run it on the water?
    What GPS speed should I see?

    What else should I be paying attention to?

    Oh yes, I want to thank all the members here who have been so helpful. I feel I have learned a lot, and I am just getting started!

    Glad to see that you are about to become yet another Polaris fanatic! I wish that I could offer some tips...but as you know by now, my ride is the MSX 150. There is one thing that may be the same for the 140...that is that the factory hose clamps are a 'crimped' design, intended to be used only once. If you find the more common worm gear style hose clamps anywhere, that could be an indication that that particular hose was removed for some reason (e.g. repairs of a related component). This would be a reason to question the seller as to why that hose was removed.... I am sure that the more knowledgable members here will correct me, if I am wrong!

    120-150 WITH THE CYLINDERS BEING WITHIN 5% OF EACH OTHER.
    Verify the plugs are NGK PZFR6H or equivelant

    I will carefully look over the hull top and bottom. Any known hull crack risk areas, potential loose fasteners, etc?

    You really should get it on the water to verify max RPM's are within spec.

    Do I absolutely need to run it on the water?
    What GPS speed should I see?
    On the 03 58ish would be acceptable, closer to 60 would be nice.

    What else should I be paying attention to?
    Call the HIN number into your dealer and verify all the updates have been performed.
    Wear ring/impeller clearance and damage to impeller.
    Easy fast start with no hesitation or stutter along the way to Max RPM.
    Make sure the system is charging 13.5 plus volts to the battery.
    If you can verify fuel pressure between 20-30 pounds.
    If you can make sure the hoses are not soft and weak indicating an overheat.
    Idle in the water should be about 1100 RPM.
    Reverse limit should be about 3500RPM but don't quote me on that one.

    I'm sure others will have more for you to check.

    Thanks for the guidance!
    I don't yet have a dealer I could call my own, but I have asked the seller for the HIN number.
    Is there an online source for what updates and/or tech bulletins were issued for the 2003 MSX140?

    Wear ring/impeller clearance - What should the impeller clearance be? Can this be measured without pulling the pump off? Am I going to need really long feeler guages?
    Can I conduct a visual evaluation of the impeller edges and wear ring health, as best I can with the boat on a trailer, and the pump in place?

    Maybe I missed it somewhere, but I have not seen an online service manual for the 2003 or 2004 MSX140. I have seen 2002 and 2004 MSX110/150 service manuals, but I would be guessing regarding what aspects of the weber engined boats matched up to the system in the MSX140. And I have downloaded the 2002 manual, which covers the Virage TXi, which I assume will be close for much of the engine and jet pump info, but again I won't know where the 2002's differ from the 2003 MSX140.
    Can someone point me towards the service manual for the MSX140?

    If you can verify fuel pressure between 20-30 pounds - What kind of fitting would I need on my pressure gauge?

    Verify the plugs are NGK PZFR6H or equivelant - I hope they are NGK, so I don't have to look up the equivilents. If the plugs are different NGKs, does that imply poor servicing (wrong plugs), or something else wrong that someone is trying fix with a different plug?

    I expect to first see, and hopefully purchase, the boat on Friday of this week. It is a 2 1/2 hour drive away.

    Seller says he bought it for $9K at the end of the 2006 season, rode it for 8 hours this summer, and is now selling it for $6K with 46 hours total on it. Says his work doesn't leave enough time to ride, and doesn't want to pay storage for another winter.
    I think $6K is a tad on the high side, but prices around here tend to be higher than in the US. Comes with single place trailer, and a Sea-Doo tube & tow rope.

    Seller's photos of the boat are below.

    WAYYyyyyy to much. In 05 I paid 5500.00 OTD for a brand new in the crate 04' MSX140. I would think you should be in the 3-4K range with the demise of the Polaris watercraft department.
    amsoil4u just bought an 04 MSX150 for 1250 with a bad engine, 1100 bucks and he's back together for less than 2300 bucks. The boat is documented at less than 20 hours (hose left off after flushing is what we were told).
    I've seen a few for sale here in Cali for less than 4K.

    Since the hull, topsides, and I imagine other non-driveline stuff is the same or similar, is there anything you have noticed on your MSX150 that I should check for on an MSX140?
    Things like minor hull or trim cracks, seat clips or stitching, handgrips slipping... I don't know what exactly, just wondering.

    Well, in 2003 the US dollar was worth about 40% more than the Canadian dollar, so Canadian list prices back then would have numerically been at least 40% higher. On top of that the Canadian market is usually priced higher (even after accounting for exchange rate differences), so I would guess that in 2003 the prices here were at least 50% higher than in the US.

    Since 2003, the exchange rate has really shifted, so that CDN-US dollars are essentially on par. For a seller inside Canada, he now sees the price he paid for his boat being WAY higher than similar used boats are selling for in the US.

    Another 2003 MSX140 seller here, which I spoke with, paid $16K (including taxes and a trailer) in April 2007 (yes, this spring) for a zero hour 2003 MSX140. He is currently asking $10K with 39 hours on it, and I just don't have the heart to offer him less than 1/2 what he paid just a few months ago!

    For the MSX140 I am buying, I took US NADA price ($3,620US), plus 14% taxes at the border, plus $200 for the trailer inspection, plus something for avoiding the "hassle factor" and extra travel costs of fetching it from the US. That took me to around $5K.
    So I started with a $5,500 offer, and ended up at $6K.

    If I could actually find a good condition 2004 MSX140 for anything near $4K, that was close enough to actually drive there and back, I would really consider it. I just haven't found any.

    Ahhhhh, makes sense.
    I was just looking at it from the perspective the dollars are about the same right now.
    Where are you Central, West, East?

    Two hours from the US border.
