    Trailer Tires to small?

    I have a 94' Rinker Captiva 180 with original trailer. I bought it from a friend last summer and moved away. While moving it to our new home, one of the tires lost it's tread and by the time I barely made it to the house before it was completely flat. The current tires are Nankang Load Max...

    Mando Alternator Install - Help me double check

    I picked up this Mando alternator used. It looks like this: I can't get it to charge and I'm pretty sure I have the connections right but I wanted to double check. B - Battery (Charging Cable) S - Jumped to B Post EXC - To positive side of Coil with a diode to stop run-on. E - Grounded I...

    Merc 470 Thermostat

    My temp hasn't been getting any higher than 120 according to my gauge. I pulled the thermostat when the engine was cold and it was open. I just pushed it closed. When they go bad, do they get stuck open? I always thought they didn't open when they went bad... This is the one I have... Also...

    Trim tab bent and boat pulling to left hard.

    My trim tab is bent some and I have it positioned straight-back from the boat (no angle). Its bent over a little and the boat pulls hard left on plane. Like, if I let go of the steering wheel it feels like it'll make a hard bank and nearly roll over. Kinda scares me with it being and old boat...

    Merc 470 Hard Cranking when Warm

    I was out on the lake this weekend and each time I killed the engine and went to start it again, it cranked slower. It ended up I got back to the ramp and it died switching between gears and It cranked over a couple times and then wouldn't crank anymore at all like the battery was dead. I just...

    A couple quick questions...

    On a Merc 470, I've read the timing should be set at 4 degrees BTDC. I've set the timing on a car before but I'm not sure how its done on this little engine. I didn't see a degree tab anywhere near the damper. I try to listen for it and I can get it timed in for starting nicely and then its not...

    Merc 470 Early Production Exhaust Swap

    I've got a 78' Merc 470 that runs well but still needed the alt conversion and 4" exchanger (not sure if its been sleeved but no leak). I found a complete 82' 470 on craigslist that had been sleeved, alt conv, aluminum manifold/cast riser, 4" exchanger, 150psi comp, new gaskets, elec ignition...

    Merc 470 Exhaust Manifold Test

    I have this manifold, does anyone know how you'd go about testing it? My coolant is flowing out of the exhaust at a pretty rapid rate (like big hole somewhere and not a crack and bad gasket). http://marineengineparts.com/shopsite_sc/store/html/product721.html I see 3 ports where the riser goes...

    Merc 470 Coolant Leak from exhaust

    Ok, I've been doing some reading and I know its either the exhaust manifold, riser, head gasket, or a cracked block. When I pour coolant in, it comes right out the exhaust and I'm not talking a drip, it literally dumps out. I put the hose in it to fill it and it never overfills, just runs...

    Merc 470 Missing and dying after about 30-60 min

    I have a 1978 Wellcraft AirSlot with a Mercruiser 470 (170hp). I know they aren't the best engines but I'd like to make it work for now until I can afford something better. I took it out last summer and it would run pretty well for about 30-60 min before it began missing out. It would start off...

    25HP Mercury Change Impeller

    Ok, I went to sell my boat today and upon firing it up for a potential new owner, it wouldn't pump water. I vaguely remember getting into some sand with it on my last trip to the lake so I figure the impeller or water pump must be out. I've not changed this before but I've had the lower unit off...

    Merc 470 Pertronix Ignitor Conversion Problems

    Ok, I just installed the Pertronix Ignitor to replace the points on my dist. (1978 Merc 470). I followed the directions during install, set the gap with the little plastic slice they give you and went to fire it up and it won't start. It does backfire and spit through the carb and slows or...

    Help Me Identify My Carb...

    I thought it was a Rochester 2GC. It has the electric choke and looks like the pictures of the 2GC. The engine is a 1978 Mercruiser 470 - 224ci. I went with the application for that engine but the carb kit gaskets don't fit. All of the metal/plastic hardware in the kit looks fine and the float...

    Flooding Out??

    Ok, I took my 470/Alpha One 78' Wellcraft Air Slot 190 out on the lake this past weekend for a trial run. I found a cracked shift bellow causing a leak that was pretty minor, a bad ground wire to the voltage regulator almost caused a fire before I saw the smoke, and what I think is flooding out...

    I can't believe I forgot...

    to take my plug out after I brought the boat home. Normally this wouldn't seem like a problem but while I was at work a massive storm came through and dumped water in my boat... no cover yet. I came home to water sitting 6-8" deep above the floor in my boat. I immediately pulled the plug and it...
