    120Hp Timing Way Off

    I'm giving my 120 Hp Mercruiser a tune up. Got new points, plugs, rotor and cap on. Reset the idle and then checked the timing. Man, it is way off. Specs call for 8 BTC and the timing marks are an inch and a half away from the gauge. Went to loosen the bolt securing the Distributor and can't get...

    Stern Drive Won't stay extended

    Ok, I had a mercruiser 120 with the pre alpha stern drive. I noticed that when extended it would slowly fall back down. There are no oil leaks anywhere. I figured it was valve body and replaced the trim motor and pump. The stern drive continues to slowly fall. Any ideas? Am I looking at new...

    Prop Pitch

    Pu the 77 Galaxy in the water for the 1st time after getting it running. Got a little water coming in from somewhere and found out the bilge pump doesn't work. After 3 hours the engine wouldn't idle. I'll be changing points, plugs, rotor and cap. My question is about the prop pitch. On muffs...

    Trim Questions

    Taking the 77 Galaxy out tomorrow for the 1st time. Got it water ready as well as time would allow. But a couple questions concerning the trim set up. I bypassed the trim limiter so I can raise and lower the unit. It would not go up. On the house it looks like I have a limiter and a sender unit...

    The 77 Galaxy Lives

    Got a new manifold for the 77 Galaxy I obtained. Installed it along with new gaskets and fired the engine up. After it ran for a couple minutes it sounded good. Temp about 140 with around 40 pounds of oil pressure. Are these within range? I have one last mechanical question. The stern drive does...

    Crack in Manifold

    Finally had a day off without rain so tore into the boat I just got. The prior owner said it wasn't winterized and I found a core plug in the bilge. I removed the exhaust/intake manifold to replace them and get a closer look at the block. No evidence of a crack in the block. Just the 2 core...

    Freeze Plug Size

    I have the Merc 120hp GM Block. 1977 model which I believe makes it a model one. I need to replace the freeze plugs. One has popped out completely and the other I can feel about 1/4 inch pushed out from the block. My question is what size. Looks like I have a choice between 1 5/8 inches and 1...

    Got Smart (Found a 1977 Galaxy)

    Ok, dropped the deck boat restoration and found a 1977, 17ft Galaxy with a Mercruiser 110 I/O. They said it ran. I couldn't try it since the battery was dead and I was 250 miles away from home. The thing I do know it that it was not winterized and the prior owners were not very knowledgable...

    Advice on Engine Swap (Got Smart)

    After reading Bond-O and his quest to eliminate OMC outdrives I have decided to look for a Mercrusier. My question is what will work. I attached a pic of the 4 cyl Chevy thats in there now. On each side thwere appears to be a steel plate that runs to the transom and is attached. The front mount...

    77 Hurricane Deck Boat Project--- Help

    Hi All, another newbie to this forum but have used it to research what I'm going to attempt. Just picked up a 77 Hurricane thats pretty banged up. My 1st consideration is the dents, dings, gouges and hairline cracks in the hull. My plan is to gut the boat, remove hardware and rub rail, then use...
