Now I've had a bit of practice posting pics, I thought I'd contribute a new thread which may help waste 5 minutes of your time.
We bought our boat, a Nimbus 3003 in August of 2018 having initially rejected her on the Sea Trial (I might do a separate thread on this to waste more time)
When the boat was launched I was informed that no anode was required on the sterngear, even though I was prepared to purchase one prior to the launch for the Sea Trial...
Anyhow, fast forward to April 2019 I had the boat lifted for a bum clean and fit a rope cutter arbour in preparation for a cross channel trip over the Easter break and it was quite obvious to me that the advice (however well meaning) was wrong and that I had to remedy it fairly quickly while the boat was held in slings, fortunately the boatyard gang were having lunch. I ran up to the Chandlers in Portland Marina, found a 40mm shaft anode, rushed back to fit it, only to find it was too long to fit between the shaft and rope cutter, there wasn't a tapped hole in the end of the shaft so no other alternative but a shaft anode. I then ran (I'm out of breath by now) round to Mechanical Services in Portland, a company with a well deserved reputation for service, to see if they had anything that would fit. They didn't but offered to machine the face of the anode to fit, I ran back to take measurements, boatyard gang finishing lunch, back to Mechanical Services (that company with the deserved reputation for good service) Had it machined to size for a tenner, they were happy with a coffee contribution, ran back and fitted it.
Here's a pic....hopefully
Some may remember this picture and the concern it created amongst some members here. Basically, this being my first motorboat, I didn't equate the effect of having so much unsupported shaft protruding from the stuffing box.
Fast forward to the Summer and we're back on our home berth at East Cowes and I showed the picture to our new neighbour who took the time to explain what the issue was, which was, the amount protruding should be no more than 1.5x the diameter, in this case 60mm, which clearly this was nearly twice that and I should take steps to resolve it at the next opportunity.
I'll post this thread now but carry on as a reply in a minute.
