I expect to be there by late Sat. AM or so. Need to pick up a serviced prop from Mike at Ocean Props and he said he would bring it to his booth at the show. Highly recommend him for prop work-very nice helpful guy. That show is dangerous! -SL

I wonder why those Packard V-12's required 100 octane avgas with their fairly meager 6.4:1 compression?

FWIW- For those who didn't see it, an 8 or 9 day only promotion by the company just ended Fri. 3/27. They offered free SPOT devices to anyone subscribing for 1 yr to the basic messengering service plus the optional tracking service for a total of $149.98 inclusive. There were a lot of posts about that on various boating & fishing sites.

I know these are "safety related," but still that's never stopped the hackers in most areas. Why not with the marine? And it's not the same as trying to repack your own liferaft. Battery is just a battery, and then there is the seal issue to contend with. But still, should still be possible." Gosh, that sound kind of reasonable. About a year ago I noticed my older (non-GPS) Alden Cat 1 406 EPIRB's battery was about to expire, then found that Alden no longer was in the EPIRB biz. Checking with a couple survival equipment companies gave me quotes of maybe $400+ give or take to replace the battery which seemed likely to include a bit of generous profit margin. I did a little sleuthing which included opening up the EPIRB case inspecting the lithium battery and tracking down the battery mfgr in France, as I remember, & then their replacement distributor in the US. Bottom line is, after a good bit of internet searching and several calls to very helpful folks in the lithium battery biz, I purchased the exact same model battery made by the same original company for about $160 and it included a new exact replacement EPIRB-case thin o-ring and a packet of dielectric lube & possibly an (anti?)dessicant pack for installation as well, not sure now . It was the same kit the EPIRB servicing outfits use. and it came with clear instructions. Opening the case (on a very low-humidity day), cleaning everything carefully, carefully replacing the battery and o-ring and carefully putting the case together may have taken 10-15 minutes and having done it once I might have done it in 1 or 2 or 3, using just a couple size screwdrivers. I just made very sure the greased thin o-ring remained perfectly seated in it's lip without being dislodged or crushed -easy. Thinking about it, there may have been both a large & small o-ring , replaced easily. Performed routine test procedure we are all supposed to do periodically and observed the proper indication , "safed" the unit and was done. Before I reinstalled the Alden on it's bracket I checked the exp. date on the hydrostatic release module and replaced that with an identical one by HAMMAR easily located on the internet. (http://www.cmhammar.com/Products_epirbs.aspx ) I think that was just under $90. I had been told by at least survival equip shop to "never open the EPIRB as there were no user serviceable parts in there" and if I was not careful with special knowledge & tools it would be easy to ruin this particular device and make it worthless. This turned out to be a rather impressive untruth and the process was easier than the last time I changed a battery on a Timex Ironman watch (easy). The rep I talked to & purchased from at one of, if not the, largest US distributors of lithium battery packs in the US, told me there was a good chance I might have to employ an included alternative connector that would involve clipping off the end of the lead on the battery pak he would send , then soldering & heat shrinking the new lead-end & connector, but it turned out the connector on the new pak was just right for easiest installation- (quick-connect). It would have been a simple process if necessary. It was long enough ago I honestly don't remember where I ordered the pak from but I can't imagine it would be too hard for interesed parties to track down the original supplier of most of these batteries. The original or present mfgr.'s supplier may be important to get a kit meant for that particular EPIRB with proper o-ring(s), etc. . The service shops woudn't sell one to me as I recall, or perhaps one did finally get back to me & said he might for $400 or so, not sure now. Granted, some of the EPIRB-servicing shops probably do have & use diagnostic electronics & 406-121.5 MHz receivers to detect the transmission signals from these units after replacing the battery, but I don't believe that takes hours of shop time , and the units do have self-testing mode to indicate working condition. It's quite possible that at least some units , especially ones with internal GPS receivers, may be able to be & eligible for SW updating. How many boaters send their EPIRBS for diagnostic tests when they 1st purchase them? ( This may be done by the raft shops if you buy it there originally . From what I was originally advised agaainst my opening the Alden, I wouldn't be too surprised if the test before sale by some of these places is simply the routine owner's check to see if the light blinks correctly. ) Have you ever seen a mfgr's public release notification of available SW update that should be sought out (other than the fact the original McMurdo GPS/PLBs wouldn't acquire for pre-positioning data and were recalled )? I don't think I have but that doesn't mean much. This DIY seemed like a reasonable option to me , especially as I have another Cat 1 (w/GPS) , a PLB and even just ordered the "free promo" SPOT device. I was going to toss the old one if I couldn't replace the battery myself and just install the newer ACR GlobalFix Cat 1 I have, so I figured there was nothing to lose by opening the old one up. it turned out the new one doesn't fit on the side of the tower console like the old one , so I'm glad I checked it out & re-powered it. I anm quite sure opening & replacing the battery on this one compromised nothing. I am definitely not advocating servicing your own EPIRB, as these are of course emergency rescue beacons you could be betting your crew an own life on . Your device may be different and you may have no interest in DIY for any number of good & valid reasons. I'm just glad I delved into the replacement issues for my Alden to shovel through some of the BS. KPS- Hope this helps a little.
