3HM 30HP engine
has just clocked up 5000 hours on the hour meter. Less than a quarter of that is ours so not really sure how accurate that measure is. I have been keeping up to date with oil
and filter changes but don't know about the past. Its raw water
cooled and did all the anodes about 6 months ago.
However, at this 5000 milestone, are there any more major items of preventative maintenance
I should be considering?
Generally runs well i think but i have nothing to compare that to.
Some blue smoke happens at maximum revs. No oil leaks
that I can see. Have to add maybe half a litre of oil as it gets closer to 100 hours after a change. Have noticed some slight missing at lower revs after running at operational revs for some time.
Looks a bit daggy with surface rust and will do a clean up when next on the hard
. Am considering taking it out so that I can access keel fuel tank
and would give it a real external cleanup and paint
job if that happens. Prefer to do the work myself but have no real experience on more major items.
Any suggestions appreciated.
