    Mercruiser 260 Backfire Through Exhaust

    He already pressurized them, that's how he knows it's leaking. I think he'd need to remove the heads, install block off plates over the water passages/top of the block, and pressure test just the block.

    In dash GPS speedo?

    My pitot got ripped out when the boat swamped. Was going to replace it until I realized that gps was more accurate and I could fill my hull penetrations from the pitot.

    1985 3.7L 470 170hp mercruiser

    Very, very unlikely. Stringers and transom as well as floor are wood. Not sure if any boat if that era used composite

    1985 3.7L 470 170hp mercruiser

    So much more to look out for in a neglected 470. But first is the structure. You need to pull up the floor, check the stringers, and drill some holes in the transom to check for rot before you sink any more money into this thing ...

    New to boats and about to burn down my boat. Need some help with wiring.

    Again, afaik no denso ignition systems in the 4.3... Someone correct me if I'm wrong. Yes, it can Don't know if they were installed on the Merc spec'd carb motors, but yours wouldn't use it. Is this the original engine? Maybe post some pics of your ignition setup. Edit: rereading this, maybe...

    Size of outboard

    Talk about a showoff, @Scott06. You have like, 230hp! I agree though, 70 hp IS pretty ostentatious. /s Also, the difference in price between a 20 yo 40hp and a 20 yo 70hp is less than the gas money needed to launch it. Still waiting for the "I have too much power, and can easily get on plane...

    Carburetor Compatibility Merc 2bbl 3.0 for my 3.7

    Fair, but just like putting any non-stock carb on an engine, it would work fine if tuned correctly. But either way putting one on a poorly running engine in hopes of it running better isn't the best strategy...

    Carburetor Compatibility Merc 2bbl 3.0 for my 3.7

    Aside from the jetting, what's different on the carbs? Both the same mercarb/Rochester's, right? But just slapping a 3.0 carb on there is asking for trouble

    Only runs when cranking

    Yes, your mechanic is correct on all counts. Ignition on should be 12v to the purple wire. Do your gauges work? If so check your dead man switch. If not check ignition switch. Otherwise you'll need to find where you lose power along the purple wire.

    Can I install a newer outdrive?

    Suspect that isn't your only problem, guessing something else locked in the drive. What happens when you try to spin the prop?

    glastron fury

    Wow, you're going to need to provide a lot more info. But the general answer is to remove the old ones and put new ones in.

    Sounds like you got a bum tool. The dimensions are the same for most (all?) I/O applications.
