Hi...I'm entirely new to boats, but have a general knowledge of automotive mechanics. The boat I just purchased (75 Invader tri-hull) has a 120 Mercruiser that has a pretty loud knock that I'm assuming is a rod knock. Question I have is what do I have to pull to remove the engine? I have removed the lower drive (prop/piece attached with 6 bolts). How do I go about separating the engine from the boat? I don't see the typical exhaust like a vehicle so I'm a little lost in this regard.
Also, the block itself has a crack (6" or so) down the side with the manifold/carb on it, just below the freeze plugs and runs horizontal. The manifold also has a small crack on the bottom outer edge, just by the drain plug. Would these be acceptable to fill with something like JB weld or is it a bigger concern? I'm not trying to be the backyard mechanic, but I don't know what direction would be the most cost effective.
Biggest concern I have is getting the engine out. Does anyone have a step-by-step to follow so I'm not just guessing? Engine was built between 74-77 based on info I found online, if that matters at all.
Thanks in advance and sorry for the very newb-like questions...first time owner of a boat...and I got hosed on this purchase....
