Gen out, Engines out?

[jcwads]

Unfortunately my Genny has had a salt water leak that I didnt notice since having the boat. The genny was very rusty inside and this seems to be the culprit. The guys at Vasey Marine have been great, the leak was the exhaust hose in the genset. A short term fix on the rest of the unit will be done, but the long term solution to sort out the genny properly is removal. I will get this done in the winter and have it stripped back and sorted before the floor corrodes through.

My thoughts are that if I am keeping the boat for a few more years, do I do a JTB style overhaul and get the engines out too. Some of the mounts are rusty and its likely there are bits that need replacing. The boat is now 14 years old, so I would like to avoid anything major going wrong in the next 4 years..

OCD or problem prevention?

My engines bear the scars of a few water leaks so I'd love to have them out for a repaint and condition check.

If your boat is a keeper and you can afford it then it's definitely a good idea to have them out, check all the ancillaries, detail the engine bay and check anything else that would be difficult to access with the engine in situ. Perhaps fit some Lumishores whilst you're at it?

OCD, imho.
There's nothing on this planet for which the old saying "if it ain't broke don't fix it" is more appropriate than with boats.

Mind, I understand petem logic, and I also indulged to follow it in several occasions in the past (albeit never to the point of pulling the engines).
But in most cases, in hindsight I must say that it was neither worth the cost nor the effort.

Any pics , and which engines and geny brands and hrs are they ?

Genny is an Onan 7kw. It def needs removal as the pan is very badly rusted.

Engines are D6 350’s with 700 hours.

Fix the genset insitu. I did this on my T40. Had some people jack it up and remove the casing and make a new one. More than half price of Onan one. I then had all bits serviced.
Got some pics somewhere.

Interesting. How did they jack it up? Did you remove the tender garage floor for this? Are you able to confirm who did the works?

There is that angle of course and that's partly why I haven't had mine out!

Some things are best kept tucked away.

I had an immediate problem that needed to be resolved on the port engine, but had the starboard lifted and sorted at the same time, purely as the Volvo guys had all personnel and equipment on site for one engine, and it would be less than twice as much to do both.. Btw, that story had a relatively soft(er) landing, but I won’t go into details on a public forum.

Personally l am a prevention is better than cure person, and if you do your man maths you divide the cost by the 4 years of trouble free boating ahead of you to reduce the bill on a per annum basis....

Probably a good idea to replace the fuel tanks as they are prone to salt water corrosion via engine bay vents

Is the generator in the oe position ie centreline, give or take, in front of the engines? If so you should be able to get it out without removing the engines - you'll need to lift the boat, then completely remove the garage floor, then you should be able to reach in far enough with a telehandler or something like that to lift the generator out and over the engines. Will require some clever work with straps to steer it out through the gap but it should be doable. I did all of this in reverse to install an Onan 4kw in mine, with the engines in situ.

Removing the engines is fairly non-trivial. I'd only do this if you have a specific problem to solve (in my case it was legacy corrosion from leaking early-style raw water filter caps). I wouldn't do it for the sake of it.

will do - it was more the email address of the person who did my repairs I didn't want to post
Just got some "daytime work to complete" at present

I tend to agree. Removing the engines and putting them back in is almost bound to cause unforeseen problems with other ancillary equipment. I'm all for preventative maintenance on engines too but leave the them in position until you have no option but to take them out for major reconditioning. I think I'd rather cut a hole in the deck to get another component out rather than lift an engine

If going ahead make sure you use someone good. Nothing worse than ripping it all out only to find a whole load more problems on reassembly. (My experience with vans & trucks tells me this)
