At the end of the day it's perhaps important to appreciate that this is a public forum and some questions always have two opposing views and there is no ‘right’ or ‘wrong’ answer. Here are a few other questions that always result in answers just like yours:
Should I leave my gear
engaged or in neutral when I'm sailing (motor is turned off).
On my Cat, is it best to run both motors or just one motor
Planning to replace my engine soon, should I stick with diesel or go electric
When I close up my boat when I am away, should I turn the power switch to off or leave it on?
Should I have bananas on my boat?
Is it really bad luck to change a boat’s name?
And that’s not even going into religion, guns
, climate change or politics. I could go on, but I’m sure you get the idea. And when you read back through the odd post there’s often two poles of opinion, particularly to a yes/no question such as you’ve asked. And don’t all such questions just invite attribution bias? But that’s another post for another day.
Polarity of opinions is one of the great strengths Cruisers Forum and makes it interesting. At the other end of the spectrum, its biggest weakness is that’s so US centric. Irrespective all responses are valid (in my view), it’s just whether you, the poster, chooses to give them credibility. And it’s not my intent to mock your post, but it helps, I feel, to provide better information and background when posing questions.
Like you don’t include the motor’s model other than 50hp Perkins, not even the year of manufacture. Perhaps it’s a 1980 engine installed when the boat was new. But it could it could have been second hand even then (not uncommon) or perhaps the current
engine is much newer, you don’t say. I don’t understand, from reading the post, how Dockhead could possibly know his Dad had one the same. Presume he knows your boat or perhaps his dad owned your boat at one time.
Perkins have made a heap of different engines over the years and where the boat was built will also have had an impact of the choices of motor
available. They often had different models/options for different geographic markets. And many motors were sold for rebranding by the likes of Ford and Mazda and Nissan
etc. After Perkins bought Gardner in the mid eighties weren’t some of the small Gardner diesels rebranded as Perkins?
Personally I would lend far more credibility to the owner’s manual of the specific motor I have in my boat than what some faceless pseudonym writes on a forum () Second in credibility would be the mechanic
that has worked on my motor on a regular basis for the last several years. Maybe there are some scientific evidence based studies/trials that you might look up.
Obviously you want your motor to last as long as possible and perform to its best at all times. So given the seriousness of the question is this the right place to ask that question?
But there are a few general good practices for a diesel:
As much as possible, when you run the motor get it to operating temperature before turning it off. Just running the motor to get in and out of the marina is not good practice.
Get it warmed up before selecting high revs. The first thing I do when I get to my boat is turn the motor on. That way by the time I get all the sails
organised etc, and get the boat ready to leave, the motor is warm and running sweetly.
And I very much agree with A64pilot’s advice: let it idle for a few minutes before you turn it off. Again I leave it idling whilst I put everything away, always takes at least 5 minutes.
And of course do the maintenance
: change oil, filters, zincs, impellers etc regularly.
And you’ll have worked out by now that when I give advice it’s the best and right advice because I am bloody perfect!
