    Well, I got my rig back from the MUDBUDDY dealer & they put a new belt on it.
    I ran it around for maybe an hour & it was ok.
    Got up in shallow water, could feel the prop hitting mostly sand on some hard bottom.
    Bingo-----just that quick, no prop turning
    No belt noise like before when it broke
    A long pushpole back to the landing.

    Called dealer service manager
    composed but not at all in a good mood
    He was dumbfounded.
    Has no idea.
    Will take a look at it.
    Just dropped it off

    I'm very bummed
    something major must really be wrong
    Mechanic said he set it to specs.
    Our duck season opens in 10 days.

    Sounds to me like the belt tension was either too tight or you have issues in your clutch or lower outdrive. If you do not already own a belt tension gauge buy one now never trust a shop. Setting the tension on these belts is nothing more than wrench work. One other note here belt tension too tight can cause major problems on your main bearings in your crank cover.... ask me how i know this... I can walk you thru any work needed on these machines, they are simple. I have torn quite a few down to a bare block and back again and have seen numerous issues on em. I would open up your bell housing cover and take a look. Almost sounds like your clutch went out instead of the belt snapping.

    Hi there Kansas
    I had mine built with no clutch.
    I called mudbuddy & Micah said that tho they set the belt tension right, they probably didn't tight bolts & do the whole belt replacement procedure correctly. He asked me to have the mechanic call him on Monday, so I'll do that.
    They won't ever warranty a belt. I'm bummed about it all.

    It ran great for 2 years, hitting bottom, rocks, stumps etc. I never new I had to have the belt checked & tightened periodically. I'm no mechanic.

    The dealer put another new carbon fiber belt on it & I hit a deadhead & it broke right away. Both replacement belts just snapped in half. Mudbuddy thinks its the replacement belts-----no stretch, no give at all & a bit different than the 2 year old belt it came with.
    Stay tuned !

    Now this week, Mudbuddy sent them some new---"Old style " belts
    Thinking maybe these new Carbon fiber belts have no elasticity----no give, when it hits a rock or deadhead.
    HUGE trouble is----our duck season here in Minnie, is underway, going on 2 weeks soon.
    I'm without my main duck rig.

    Ringbill, any updates on your rig?? Hoping it is just a bad lot of belts. Down here a few got to hunt early teal, mostly northern Florida...as I said earlier, the high water has not been a good thing, forget using waders, though I mostly don't, and it is raining again today, hoping someone can shut off the spigot.

    Hello there Glades,
    I just got it back this late afternoon for the THIRD time.
    I'll take it out & test it out tomorrow.
    It's been pretty warm & wet up here til a few days ago.
    Summer ducks are leaving now ----32 this morning, they say 22 tonight.
    So that'll move more early season trickle flights in here, as ringers & redheads are now showing up.

    Hoping that will do it- the best of luck! Glad to hear temps are down; our big lake is at the highest level in 12 years, the glades are also very high, just waiting on November and the first ringers, does my heart and soul real good to see them each time!

    Have them check the sprockets/shafts for high radial run-out. a few thousandths of radial run-out will cause big tension spikes in the ultra high modulus carbon fiber belts. And loose belts try to climb/jump teeth, which if the belt jumps teeth, the tension can go high enough to bend shafts/break belts.

    I'm not sure what yur saying----technical stuff.
    Mechanic did out a micrometer on everything & was ok
    Mudbuddy engineers said he did things right, he even sent them photos.
    They are thinking it's the carbon fiber belts----no elasticity
    It broke 2 carbon fiber Opti-belts immediately when I hit a deadhead & a rock.
    Snapped the belts in half. No sign of any wear anywhere else.
    They just sent & installed a new "oldstyle" ===original type belt.
    Only time will tell
