Chances are your boat is like a member of the family. There will be rust, frozen bolts, parts to replace, and probably great difficulty in getting those parts. So basically there was nothing wrong with the old way, it just didn't agree with what everyone else was doing. Re: mercruiser inboard ignition wiring Reply to Captian,and anyone else with ideas!

I'm trying to do something I think a little unconventional simply because I think it would be fun. It is possible that the alternator is not functioning properly. It's also a good idea to purchase a service manual for your engine. Wiring colors will vary slightly depending on where the company takes its readings. We burned the flywheel up in the starter trying to figure this all out before. We were fortunate that for years there was an engine mechanic near us who would give us excellent and detailed advice whenever we had a do-it-yourself engine job to tackle. The difference between the two is what is under and behind the boat.

Upon looking in the bilge area, I see that a lot of the boat wiring is just cut off, with no idea of to where they were coming from. Come to think of it why not? Ignition switch feeds command wire to the starter solenoid start position. Also, what size connector do I need for my starter? Right now my positive cable is three feet long and the negative cable is just over six feet. Batteries 2 and 3 will be wired in parallel to increase your reserve capacity, but keep the voltage at 12 volt. I believe,in the olden days, cars had a design something like you envision. Don't wanna have to rebuild it again. Dig our Boat Wiring Content? It copies the exact size and angle of the real engine and can be aligned with the prop-shaft coupling, revealing whether there has to be any change made in the engine bed or mounts long before the engine is swung into position.

Wiring a start switch

Re: mercruiser inboard ignition wiring No, it starts when you manally turn the key over to the start, but when you let go of the key it continues to try to start the boat by itself unless you turn the key to te off position. One side of this T can then still be used for the air vent while the other side can be used for the fuel-return line. I can't quite figure out what needs to happen where. Resistance wire between the key and the coil. Hope this helps, Kevin Kevin, My boat wiring question is simple. I am now considering adding a second house battery to my boat. I think I read that this idea is not applicable to my boat? Everything else is wired from there.

Boat Battery Wiring

Color coding only comes into play for engines and instrumentation, until you get into the newer big yachts. Could you please tell me if it would work with my current battery switch? The classes cover the theory of operation, explain all the parts of your new engine, cover routine maintenance, and include a hands-on session that gives participants the opportunity to do routine maintenance on the engine they will actually own, including adjusting and bleeding it. This way, even if your battery switch is off, if your boat starts filling with water the pump will still kick on. These smaller dimensions in width, height, and length make it almost certain that your engine bed will have to be rebuilt to accommodate the smaller engine, since its mounts will probably be closer together. As for the propeller, there's a 50-50 chance that the new engine may rotate in the opposite direction from the old engine.

Installation Drawings

Just hookup your existing boat wiring infrastructure to the terminal block and buss bar. If you're already using a flexible coupling between the engine and the shaft, chances are that the bolt holes in this flexible coupling or Drivesaver will not match your new engine's coupler, and a new, matching, flexible coupling will have to be purchased. It's also likely that with a new engine, the water, fuel, and exhaust systems may have to be rebuilt or re-sized. I wouldn't do it but that doesn't mean that you shouldn't. With a large enough amp you could easiler make the vsr cycle or chatter several times per second. If the heat-exchanger water lines from the engine to the hot water tank slope upward, an air-lock can develop in the heat-exchanger coil in the hot water tank that will prevent water flow and, consequently, heat exchange. Often they will have a battery test feature with a moving coil meter.

It seems awful complicated though and you'd have a lot of switches and connections to go bad. Someday standards will be the same, but not just yet. Most owners will hand over the repowering project to a knowledgeable, qualified, and reputable installer. One way to overcome this problem is by installing an expansion tank at the highest point in the water lines at the hot water tank. If you have 2 batteries that have 100 Ah of capacity connected in parallel, you have 200 Ah to recharge. I really hate having to drag my accessory boat battery out to recharge it when away for a two week vacation in Canada.

Also its a tiller motor. The different systems can be done by simply taking the main feed usually red and splitting it to both the supply of your toggle switch and your button start, the 2 wires from there to the choke and starter. We just had it rebuilt and replaced. But when a diesel is up in years, cylinder walls and piston rings are worn and fouled with deposits, so they no longer make a good seal.
