Has anyone ever seen one of these, or had one made? My boat has a full enclosure but it's too much trouble to put on/take off every weekend. Thanks in advance.

My '89 340 DA has a 6.5k Onan MCCK. White in color. A prop shaft seal leak is not uncommon. If you're all original, you don't have dripless. You might have to repack the shaft seals. Can be done in the water. Is much easier to do if you remove the exhaust collector/crossover tubes on both...

This pic is from an automotive application, but should be close to what you have. The spring that holds your choke closed is inside that square looking thing attached to the intake manifold (the red thing). It's a bimetallic spring that uncoils as the engine heats up. Yours may be broken or...

This isn't exactly an answer to your question, but I'll just add that I would recommend you watch several YouTube videos and study the appropriate service manual to get familiar with how the Quadrajet works. It's not complicated, but it does take some time to figure out how everything works...

Lawyer here. Recently decided to focus my practice on the emerging area of drone / UAV law. Also a pilot - commercial, multi-engine instrument. www.txdronelawyer.com

Follow up question on this - do you know if the wood goes all the way to the bottom of the hull? When I look inside my e/r I can see a thicker portion of the transom up above the stringers where wires, trim pump, battery charger, etc are screwed into. I always assumed that was a piece of...

I think the 8 pin controls advance, so yeah probably no springs and such, but I'm not certain. You'd probably have better luck in an automotive forum for that specific question.

Looks like that may be commonly known as the GM HEI 8 pin module. It's supposed to have two sets of wires plugged into it - surely yours did? If not, then you should find out why.

I'm pretty sure that rectangular thing with the numbers is an electronic ignition module. I don't think you're going to have any weights or springs. See link below - have no idea if this is the right part #. The later model Merc modules aren't like this...

Correct. There should be a published advance curve for whatever system you have. You can test the advance by running the engine at 1500rpm or so. It won't be fully advanced at that speed but you'll be able to see if it's working. It isn't good to run your engine over 1500 in neutral. Some Merc...

You can download your owners manual from Sea Ray's website and it would have the details. I would guess you have 2 deep cycles hooked together that are either on the 1 or 2 position and then a starting battery on the other position. Your alternators may run through an isolator then to each bank...

It sounds to me like your engine is loading up while sitting at idle in gear, so the rpm's start to drop, you get the characteristic rattling, then the engine dies. That sequence is something I'd expect to occur if you need a tune up. The transmission isn't going to get hot sitting in gear for...

I agree with what's said here, there are numerous instances of v-drives rattling at low idle and/or when there's an ignition issue such as plugs, wires, cap, rotor. You can have a miss on one cylinder and it's hard to tell any real difference in how the engine sounds. Don't jump to an expensive...

+1 on the dead AGM not taking a charge. Same thing happened to me over at Grandpappy. They can be brought back to life though. Good luck!

There's a regulator inside the water connection housing. Mine randomly does it. See link below. http://clubsearay.com/showthread.php/1923-Water-Pressure-Regulator

So after the event it's taking more engine power to make the port propeller turn the same speed as the starboard propeller. I don't think your transmission is slipping - if it was slipping the port engine would have to turn more RPM's to turn the propeller the same speed. Something is wrong...

So to sync the engines at 3200 rpm you now have to advance the port throttle two inches past the starboard when before the incident they were even? Or are you saying to get an even wake or output (from looking behind the boat) you have to advance the RPM's on the port engine to where - for...

Seems to me that if the transmission was slipping the engine RPM's would be higher at every given throttle position. Given the description, that doesn't seem to be happening - buy maybe I'm reading it wrong. Having to advance the throttle further to achieve the same RPM seems to indicate...

+1 on the last two responses regarding safety switches - my only additional comment is that I think a relay or two may be involved in the start and run circuits, so if the two or three safety switches check ok, but it still dies when you left off the start button, it could still be an electrical...

Agree with all that's said here. You probably have four barrel Quadrajets. There's a ton of info about them all over the internet, they were widely used in the marine and automotive industry. Pretty simple to understand their operation (and overhaul if you're so inclined), but there is a...
