    water pump impeller

    Gear box is probably an overstatement on my behalf. There is a horizontal plate  (anti cavitation plate ??) below the impellor location. Below that plate there is a 'bulb which has oil init and I guess some form of cog to change drive orientation from horizontal to vertical (shaft spins horizontally, prop vertically) - that's what I am terming a gear box. But remember these outboards have direct drive (motor running = prop turning), no neutral, no reverse,  just go and whoa. To go backwards you spin motor 180 degrees.

     

    I might ring Murray I think,  he seems to carve out a nice life from outboard servicing but thanks anyway for your input.

    Thank you Wheels. Anybody else? I will say (and accept that I did not before) - it seems not to withdraw easily as most reasonable folk would expect.Even gentle (& I do mean gentle) persuasion from my old mans engineers hammer seems to make no difference.

     

    I have read somewhere that there were some models where you had to remove a circlip from the bottom of the shaft (i.e. inside the 'gear' box - not

    that this O/b has more than 1 gear). To get to it involved more stuffing around than is reasonable and I guess its fair to say the Yammy engineer who designed it may have had better days.

     

    I'm hoping this isn't one of those motors.

    darwin award

    woops. source was NZ Newswire on MSN site.

     

    Who gets the award? the numb skulls that were rescued or the 'authorities' who have to think about whether to investigate. God knows how long it

    would take to decide if they should prosecute.

    Seems to me the authorities should take a concrete pill and do their job. If they don't, idiots will always act with impunity, and meanwhile those

    who do act responsibly get accused of wasting 'responders' time.

    I think the rescued people on this occasion should pay for it. No life jacket no excuse

    I thought that young woman was never found? And no trace of either. All very odd.

     

    But back to the topic - buyer beware if you ask me. Maybe the potential buyer is a super gung ho boat guy, a kind of maritime Bear Grylls?

     

    Hard to say without a link to the auction Brendong - you haven't said if the vendor is maintaining it could get to the south island or not.

    John - did u say your old girl drew 6'5"? I thought Garden Cove was out of my depth now because I am 6'3" (I'm a 'modern classic' as they say at

    Mahurangi)- I would love to go in there again, its such a gorgeous bay.

    Why should we be surprised?

     

    Oil barons and governments worldwide have been gouging our wallets for decades and we all know there is a plan behind their

    misbehaviours (the old "how can I line my pocket out of this and screw the rest of you" plan).

     

    Reported today on MSN (I saw it today is what I mean) that Bloombergs (whoever they are & I have no idea about that, or their credentials) warn

    another oil glut approacheth (oversupply leading to price crash), and I think they intimate that it is part of a strategy to undermine the oil

    industries 'boogie man' i.e. electic cars.

     

    Supposedly the next 2 years could see EV's at the $30000 mark although I guess that is USD, and also probably the cheapest and most basic of cars.

     

    I'd buy one right now if I could afford it.

     

     

    I imagine all that will change is that those who currently invest heavily in oil, will have long ago hedged their bets and ploughed part of

    their gains into alternatives fuels so that when the change gets going they will be positioned nicely to continue reaping benefit from the gouge.

     

    Bastards? Or is that the spirit of investment?

    Whatever your belief it just goes to show that we are a greedy species. Oil and the downstream effect of its use pretty much shits in our own nest andyet we continue to guzzle. and those who invest in it do so because of the massive returns they can achieve

    Reviving dead lead acid batteries

    Thanks IT - Weiti is home these days :) and hopefully I am about to become a member of that revered establishment - as long as Nevenka doesn't tell any lies about me that are believable it should be in the bag!

     

    I think you are right about the meter ID - cant recall exactly but it sounds similar. Was on the ship when I bought her and it has always just worked.

     

    I'll give you a call one day shortly maybe later in the week. It would be nice to sort it as I just get annoyed by these things.

    Reviving dead lead acid batteries

    in TechTalk

    Posted

    Wheels what would you say about this - I have 6 year old deep cycle house, and start batteries, both FLA, charged thru BEP VSR system and monitored by BEP meter that shows battery voltage, capacity (in a/h and %), and charge rate. It seems that the meter only monitors the house battery capacity,  but it reads both house and start voltage, and charge rate obvioulsy only when alt running. The meter reads V & AH even when batteries are switched off.

     

    I have regularly over the past couple of years found the house battery discharging at 0.2A with everything off, batteries off at isolator, switches - everything off. This discharge seems to continue slowly  (i.e. it doesn't suddenly spike to 1A or 5A discharge or any other number - always 0.2A)  until the AH are depleted to zero, and apparently house battery voltage to zero too, because the meter does not read anything.

     

    Here's the bit that confuses me. With meter unresponsive I can start the motor without paralleling  (it would seem pointless anyway) - every time, so that tells me start battery is healthy as? Meter wakes up, and immediately voltage on both batteries shows as 13.9 V,  charge rate reads high (say 30 or so A maybe higher can't recall), battery capacity then increases over several hours and it all looks normal. After several hours of charging with the expected reducing charge rate (I think this means the alt is working as it should and also meter too) the house batt will jump from say 45% capacity to 100%.

     

    My understanding is not great but I believe the V reading with alt running is somewhat of a red herring because the meter reads the V while battery is excited?

     

    Anyway -  I turn it off and again - everything off, 0.2a discharge and here we go again.

     

    Seems logical that the house batt may be poked after extended periods of apparent discharge below the 10.7 V range (which I think I have been told is technically flat for FLAs?), and I've been told that I must replace both batteries at one time. Is that correct?  And how would you go about finding the big hole that's getting all the 0.2A's. There's got to be a barrel of the bastards there and if I could get em back I'd be sweet :wtf:

    2 be honest I am electrically incompetent so I guess best would be to go to marine sparkie person - do you know of one around these parts that I can trust to get my 0.2's back?

    lunatic fisherman in Weiti River

    in MarineTalk

    Posted

    Just a word of warning to anybody using the Weiti - today I came into the river at

    about 4pm when the tide was still pretty low. I draw 1.9m and so I was crawling alongat a knot or 2 at most.

    Madly gesticulating Asian fisherman on north side just past the cable marker drew my

    attention to his fishing line that had been cast across my path, and so astern I went

    while telling him politely he'd better wind it in because I could not turn around -

    he did so but didn't seem too enthralled..

    I had gone ahead again and within a few seconds heard the distinctive noise a sinker makes when it hits the water, I looked at the source of the noise to find a yellow

    braided fishing line with hook bait and sinker had been cast between my topping lift and mast. I tried to get it out of the water and back through but had no chance and ended up breaking the line from the end of the guys rod to my boat - I guess a distance of 30meters.

     

    Then I noticed the bloody sinker and thought about it! 40mm long tapering from 5 to

    15mm in diameter.

     

    If you are navigating this area beware - these people have no regard for your safety.

     

    There was a bunch of other fishing people witnessing this - if anybody knows the

    identity of the Asian guy (not the same one) let me know. I'd like to get somebody

    dressed in blue to speak to him. If I'd taken a direct hit the feckin nutcase could

    have killed me.
