Merc 90 can anyone throw some details for me?

Hi all,
brought this from a boat that was damaged for "not a lot"! runs sweet but i dont know alot on it. Its an auto lube from the 80's i was told.
Any ideas? Are they any good?
Cheers

Nope they are rubbish - I will give you 700 for it :wink

Strong motors. Looks a tidy example. Usual things that fail are the engine mounts and tends to leak fluid from its main tilt ram. The scraper tends to come away from the seal end cap causing a weep when tilting up". The old 3 wire 3 ram system is quite hard to get hold of too but yours looks like the single ram 2 wire so you'd good

Other than that they are powerful engines. I had the 80hp for yeas on a fishing boat and it never failed us!

If its got an internal oil thank then its similar to mine. Oh its has from the piccys so not a auto blend ( external tank type ) but nice internal tank.
my 75 is still going strong 20 years on.
very good engine.
looks like mine a 1991 engine

If you dont want it i can take it off your hands LOL

I'll re-phrase, it's a two smoke outboard from the eighties when fuel was 1 a gallon!
