I need a front main seal do i have to tear the engine apart to replace that

your awesome i tried looking it up but i was looking up mercruiser not GM so did it come out of a vehicle? because i took this out of a 1977 Caravelle 17' runabout

The first two numbers are stamped in a milled shelf on the block the only numbers on it

well its a complete running motor so I was just thinking of putting it in there as is but should it need something I was just wondering if my stuff was better or if the new one was better

I have a 165 in my boat but the water jacket was vcracked when i got it well its gotten so bad i cant use it anymore icame across this engine but its not quite like mine just wondering if my parts will fitthis first one is what mine looks like and the second one is the one i got different intake...

These are the only numbers on the motor

So i finally got the boat out and had some fun BUT i changed the oil in the outdrive i filled it till it came out the vent hole on top and now that gear box is empty and its leaking out of the bellow what seal would that be

If I don’t use the lead sub should I use premium 91 octane

That’s what I thought thank you

So regular gas is fine?

I stuck with the mechanical fuel pump but do I have to use leaded gas or the substitute or can I just use regular gas

Also what are the best spark plugs and wires to use

Thanks I thought so but wanted to make sure where do you guys get parts I may get a new fuel pump and impeller kit
