I highly recommend putting a dial indicator on the new pulley, if it is not as close to perfect as you can get it time will take a toll on the mounting brackets from bad vibrations! A friend of mine learned that the hard way haha

Make sure and seal up that cut deck w some epoxy too

I saw the ones that came with a pulley that you add on and have to set up with a dial gauge - the one I got runs the belt off the existing harmonic balancer. I wasn't looking forward to laying on the deck, messing with the pulley - I would have done it but really liked the simple installation of the Breezeworks kit.

Thanks Smoke - good catch. That had slipped past me - I'll do it.

Hey scook,
My 170 was converted over to an external alternator before I got it. It has worked fine till yesterday when the adjusting bracket broke and the alternator fell off damaging the alt. fan. Gotta fab up a new bracket. Mine mounts on top of the front engine mount with a adjustment bracket that mounts to the motor water pump. I think years of a little vibration and metal fatigue finally broke my bracket. I bought a new marine 105 amp alternator years ago from Rare Electric out of Cherokee N.C. for 67.00 about eight years ago and its done great!

Hey Bro' Felton,

Sorry to hear about the busted bracket - hopefully you're like me and enjoy little fab projects like that. I wonder if there's a way to work a rubber grommet in the mix somewhere to dampen the vibration? Anyway, I hope you get the old girl going soon - this is the season. Also, very happy to hear about improvements on the home front - that's the really important stuff

Thanks Scook! Made up a new bracket and fixed the alternator fan. Got it back out on the river with my baby, and all ran great. Did your conversion kit work out ok?

The conversion is working great. Haven't got many hours on it - kind of screwed up my back pulling my anchor the hard way and am taking a while to heal up. The boat's in better shape than I am right now but I'm getting better.

Sounds like you need an anchor ball. No need to pull the anchor, let the boat do it for you.

Well Ferm, thank you very much for bringing up the subject

That's the REALLY stupid part of it - I have an anchor ball. We were moving a little way to the side to get to a slightly different depth (under any given conditions, the fish tend to swim more or less single file up the river). In my pea brain, I thought I'd just pull it by hand and get it done. We use anchors that have pretty long tines and it was buried in the sand real solid - so much for being smarter because you're older. It's hard to remember that I'm not 23 any more.
