Evinrude 150 "flooded" / electircal problem?

[Mike Langianese]

I posted this earlier this evening but it disappeared from the forum I hope I didn’t violate any rules etc.<br /><br />Well I’m no longer a boatwantabe, bought one yesterday and need you help. The boat has twin Evinrude 150’s, Model E150NXENC, E150EXEM---unreadable , serial numbers GO3076183 and GO3014951. <br />Where shall I start to get the boat shipshape? I have a problem with one of the engines, Was to go on a sea trial before purchase, when arrived at the dock a “hand” was replacing the spark plugs on the starboard engine, the port engine was idling. He said the Boat Broker had the boat out the previous day and thought it could use some new plugs… (I was very suspicious of the whole situation) <br />The engine started, I did see the water stream from the rear of the engine, the broker trimmed the engine down and accidentally killed it. Tried to restart, no go, starter very slow, they said that they just put new batteries in the boat but must have left the pumps on over night and the battery drained. ( I pointed out that the pumps are on automatic switches) They said that it was flooded, took the cowling off tilted the motor up, took I don’t know what it is called but where an air filter would go if boats had air filters, took that off, unscrewed the fuel line and about a half cup of gas spilled out. They did this 3-4 times, the starter went slower and slower, they put a charger on this battery. They attempted to start the engine I noticed electrical smoke coming from the joint on the steering connector between the engines. I insisted that they stop screwing with it and we re-negotiated a price for the boat with only one working engine and took the boat home.<br />With the paperwork for the boat the original owner included several receipts for work done this spring, including new batteries, fuses holders for some electronics and engine tune-up ect. It appears to me that the boat has some type of electrical short that is draining the battery(s), don’t know if the other battery is effected.<br />I am charging the battery, should I put some ears on the engine and try to start it or is there a short somewhere that I should find first? The boat did perform OK with just the one engine, but it is a twin…<br /><br />I just found that where the power enters the engine, heavy black and red wires, red attached to a terminal that is part of a black plastic square shaped object, on what looks like could be the starter, could this be the starter solenoid? This assembly is loose, can move it around, don’t want to mess with it without a manual (I just e-mail requesting availability and price on MFG. Repair Manual for engines) or advice from someone knowledgeable.<br />Sorry for the long post but I wanted to give the engine detectives enough information to work with.<br /><br />Thanks for any help<br /><br />Mike

hello<br /> If you saw smoke from the Tie bar then stop now and find the bad engine ground. what is happening is the engine is trying to ground though the tie bar. sounds like some one did not use basic trouble shooting to isolate this. anyway it also sounds like the broker and the techs may have been trying really hard to sell this boat. good luck and keep us posted

Whew!! You are a man of much faith buying it the way you did. Your broker sounds like a used car salesman. I bought the one I have now knowing that one of the motors was frozen and heavily discounted the price. Hope you did not get bit too bad. Anyway:<br /><br />First thing I would do is pull all of the spark plugs and make sure that the engine turns over easily (to eliminate possible problem of internal binding). You should be able to turn the engine over easily by grabbing and turning the flywheel by hand. If that is OK disconnect the battery cables, clean & reattach. Do the same with the starter solinoid. I would smear the connections with a diaelectric grease which you can get from an auto parts store. Then give it a try - with the muffs on of course.<br /><br />Since this bost is new to you and from your post I take it that boating is new to you - you might want to invest a few bucks and have a marine mechanic go over the motors WITH YOU there. He should know what to do and ask plenty of questions.<br /><br />Did you get any kind of warranty?

I have NO trust or faith in this boat broker, but that is a another story. I should post a saga on what not to do to warn other new buyers. I think I got a deal on the boat even if the engine needs a new power head.<br />Back to the engines. Port engine ran fine, started, re-started etc, Starboard engine Started, idled for a few minutes, died and didn’t restart. It is not locked up, turns freely, etc. <br />The advice to have a mechanic go over the electrical system is good was I correct in my assessment that the wires connected to the “loose” contact area is the solenoid? Is it a straightforward removal? Take off, inspect all wires for warn insulation and replace with a little dielectric on the connections?<br />Thanks for any comments, help<br /><br />Mike

SoLittle and anyone else who may have an opinion or advice.<br /><br />I removed the plugs and spun the engine by hand and it seems to be OK.<br />I removed the wires from the starter solinoid, cleaned and replaced. The battery connections were already off, when I went to connect them back to my surprise both cables are black.<br />I have duel batteries, duel engines, each battery has a pergo switch, the battery in question has a black cable from the pergo switch. I checked the other side and found all 3-cables from the switch were red/positive. I also checked some wireing diagrams from another site and found that the switch should be Positive. Is this correct, i would hate to cross wire the thing. <br />I did order a manual and picked up a chilton from the store, <br /><br />thanks for any information<br /><br />Mike

IT LIVES!!!<br />I was able to run the engine on ears tonight, started right up. <br />Thanks to all to offered assistance and advice.<br /><br />This may help some other newbees so here is what I did:<br />1. Removed all connections to starter solenoid, cleaned the contacts and replaced using a dab of dielectric grease on each connection.<br />2. Charged battery.<br />3. Cleaned all connections at battery. Checked all battery cables for polarity.<br />4. Removed plugs and spun engine by hand as recommended to check for "binding"<br />5. Flushed the engine <br />6. Removed plugs and checked for correct gap and plug. These are new plugs, installed by the seller at time of purchase.<br />Found that they were gapped at .40 while .30 is recommended also the Clymer Repair Manuel states that this engine must use a suppressor type plug or erratic ignition may result. Plugs were NOT suppressor type. Replaced with proper plug.<br /> <br /><br />thanks again<br />Mike
