sealine S37 the outcome

[[2068]]

One thing for me, what has caused the sump to corrode? On the inside it is full of oil, which unless badly broken down should not be corrosive, and on the outside fresh air. Yes, there might be a bit of brine in the air, but enough to corrode the sump?

Leaky raw water pump, previously, or leaving salty bilge water sloshing around.

Or actually fixing oil leaks

not sure why is has correded like this paul suggested that it may have had water left in it over the winter before the seller owned it but who knows

the main thing is it will be sorted and ready for me for the next season, the other engine is in very very good condition all over so its a bit of a mystery but it will be sorted

i will post some pics up now as its my boat in a new thread

cheers

Common fault on most tin sumped ad/ kad series motors, there has been a substantial amount of sea water sat below the engine, net result lumps of rust along the underside of the sump, you could see the tide marks on the grp too.

Most of these series motors suffer sea water pump leaks which damages the alternators and timing cover which require replacing when there bad as oil leaks then appear.

This boats been sat for a while with sea water in the port side bilge, the starboard motor was more or less as it should be.

The interesting part will be attacking the repair as there is no way the engine will come out the boat due to a typical sealine build process, ie engine fitted before superstructure, the hatch is very small with no way f making the hole any bigger unless serious amounts of grp are cut and re glassed in after the job. I will send pics to show at a later date.

VP, I agree re engine access. There are any number of boats that I look at and think, what if? Especially regarding major engine surgery. For me, Sealine are amongst the biggest culprits.

Dont understand the logic with the engine hatch size! We have an S37 and whilst its a fantastic boat i can hardly get in the engine compartment never mind Kad44s coming out .

Doesn't apply to all Sealines.

Engine access on an S28 with KAD32's is just fine.

Thanks for everyones kind words but it's my job which I enjoy very much.

When I returned home last night and watched DIY SOS there the guys who bring joy into peoples lives who need and deserve it.

And you are bl**dy good at it Paul?

Back in 1997, our brand new S37 had to have both engines removed after the service agent overfilled them with oil at the first service which blew the rear crank seals (or something like that) depositing a great deal of oil in the bilge even though the level was still an inch over the max level on the dipstick, during a trip to Guernsey. These were Mercruiser engines, quite big 6 cylinder units. They were removed with difficulty, using a Hi-ab (?) crane without cutting any grp flooring - might that work with the VP's Paul?. All covered under warranty of course, but boat out of commission for 8 weeks. Just a thought, no expert!

I’m a 10st kind of bloke and don’t have any problems with the S37 hatch. I’ve got KAD43 lumps and don’t expect to move around the compartment easily but do all the service stuff with reasonable comfort. Replaced the turbos last year and almost enjoyed the job.
