1992 carberated ,410hp ,502's are 'not' tall decks right ? Do they have inconel valves stock ?

Come on ,where are all the engine pros ?? You know ,those big heavy ,metal things in the back of the boat which we spend most of our day dreaming about making them bigger ,better ,faster !

i'm not expert but i am pretty sure that it isn't a tall deck.

NO and NO
answer your question?

The Mercruiser 502 carburated engine was produced from 1990 to 1993. It was offered in Generation 4 and Generation 5 configuration. Neither of the generations were tall deck. But all of the exhaust valves in the engines mentioned above do have Inconel valves. The intake valves are stainless steel.

Oh no ! I'm confused now ! I have 3 people telling me they don't have inconel and 2 saying they DO ! Different sourses included . Not to nock anybody ,but someone is wrong . Who is it ? I'll let you guys fight it out now !

THanks for all the answers .I know we all try .................

i woudl also lean towards the no iconel valves.

I dont; thin they even use iconels on the new EFI engines. I htink only the supercharged engine some with them. Search teh archives i know this has come up before.
