What is it......And an engine quit on me

What is it......And an engine quit on me
  • Skipper_SteveSkipper_Steve October 2010

    Ok, 2 questions here ....I have a 33ft 1968 Alglas with the Lectra San toilet system on it, my understanding of this system is that after treating waste, it is discharged overboard, I have a cap on the bow of the boat (similar to the fuel and water caps) that most of the writing has been worn away, but I can read the word "waste" on it. This appears to be a factory fitting. Anyone have any idea what it is for? (besides some kind of waste :-) )

    My second issue is that I was tuning up the engines a couple weekends ago, the starboard had quit running on me, the port ran fine (according to the previous owner, the port just got rebuilt last year, and I just bought the boat 2 months ago). I replaced both fuel filters, and all spark plugs on both engines, now the starboard runs fine but I cant get the port to run at all without spraying starting fluid in it, it will fire until it runs out of fluid then dies. Any ideas what I can check? The only thing I did differently with the port engine was to unscrew a small screw on top of the exhaust elbow, which sounded like it released pressure, I have screwed this back in.

    Thanks for any/ all advise

    make sure your fuel filter purge is in the closed position. just a thought. Otherwise, check your firing order, one of the two motors could be counter rotating, meaning one could turn backwards, so make sure your firing order is correct.

    18436572 (left hand rotation) then the counter rotation engine should be 12756348 (right hand rotation)

    Steve,
    Are you getting fuel when you pump the throttle? Did you change your fuel filters? This ethonol gas is the pitts and not only does it not run worth crap, it will loosen all the crap in your tank and send it to the carb.

  • Rich_PRich_P October 2010

    If it will run on starting fluid, the plug order is fine. Do not keep it running on starting fluid, it is not good for the engine. You have a fuel issue. Best case scenerio- you bumped a fuel line and it is no longer sealed letting air in (although good luck finding). Other fuel filters could be cloged (on mine there is a screen in the tank inlet, a water seperator, a fuel filter, a smaller fuel filter on the engine, and an even smaller one in the carb inlet). Then the last thing to check would be fuel pump.
    You can try getting a mity-vac and drawing the fuel through the lines to the carb first and see what happens.

    The Lectra-san is a type 1 MSD and does treat waste. You can discharge a type 1 MSD in US waters designated as "discharge" (meaning discharge of treated waste only – not macerating untreated waste from a holding tank overboard) - make sure you clearly understand if you are in a discharge or no discharge area.

    The deck fitting that you are describing is for pumping out a holding tank. Most likely your boat was built with a small, aluminum day tank that was connected to this fitting by an 1 ½” sanitary hose. The Lectra-san was probably installed later, so you'll have to follow your plumbing to see if it transfers the treated waste into a holding tank that can then be pumped out.

    Depending upon the waters that you boat in, your waste handling system will get a thorough inspection if you are boarded by the Coast Guard or other regulatory agencies, so make sure that you understand and comply with waste handing regulations in your area.

    Hope this helps - there is a lot of information available on the web that explains this in greater detail.

    Forgot to add that I had a similar issue a few years ago where an engine suddenly stopped and would only run when hooked to a small gas can. After checking all of the filters mentioned above, I found that the gas pick-up line in the tank feeding the engine was plugged up. Don't know if you have two tanks and can cross feed gas or not, but if you do, try running the port engine off the starboard tank. If it runs, focus on the pick-up tube.

    also check and make sure all clamps and fitttings are snug

    Hey Skipper_Steve,
    I had a recent similar problem as well, I have 4 gas tanks (2 primary and 2 reserve) with mechanical fuel pumps took me a while to figure out I needed to close the tank feeder valves on 2 of the empty tanks, its easier to pull air than liquid, once I closed off the 2 reserve valves both motors fired right up. Now I only run 1 tank at a time. if the motors are running and I open one of the empty ltank feed lines the motors die, close the valve and they fire right up again.

    good luck and welcome aboard!

  • skipper68skipper68 October 2010

    Make sure the shut off is turned on in the right position, alsoif you have a check valve that might be stuck. It's so hard to figure these things by post,compared to hands on. Stargazer is on the money also. G"luck

  • Skipper_SteveSkipper_Steve October 2010

    Thanks for all the comments "check this and Check that" I'm not used to having so many filters to check (compared to an auto) I'm going up to Toledo this Wed for one last trip on the water (I hope) and hopfully will get this figured out. The boat won't leave the dock with only 1 engine running ( I may be new to boating, but I'm not stupid!)

  • skipper68skipper68 October 2010

    It CAN leave the dock on one motor,but it's not fun trying to dock on one motor!! Ben there,dun that!

  • Skipper_SteveSkipper_Steve October 2010

    My 1st trip in this boat I had to come in on only 1 motor. Actually, that was also my 1st time ever driving a boat like this. Stress level was off the charts, also lost the flybridge steering at the same time (chain snapped)

  • skipper68skipper68 October 2010

    Yikes! Well,that was a fast education! Let us know what you find out.

    Hey there, Skipper Steve........What did you ever find the problem was with your engine ? After reading all these posts, it peaks your curiosity and you are left wondering if any of the info helped, so how about a comeback if you get a little time ? It might just help someone else with a similar problem. Thanks....Lee

    I think I have the problem narrowed down to the fuel pump, however the boat had to come out of the water before I could get back to the boat to try and fix it ( the boat is 4 1/2 hours away from me). So that will be my 1st project in the spring.

  • ok, I spent last weekend on the boat, still in drydock, working on the engines, I spent 5 hours on the engine that didn't run, chasing down parts, etc. Got to the point that I was getting fuel into the carb, but it wouldn't fire, then I realised that my distributor had vibrated loose, and was spinning about 2 inches either way. After "cold timing" the engine to get it close, i tightened up the dist. lock nut, and the engine fired right up. I'll take a timing light with me when the boat gets in the water and get the timing set properly. With the boat out of water, and not having a hose to pump water into the engine, I didn't want to run it to long. So there you go, if I would have checked the distributor first, I could have saved myself several hours of frustration. Both engines fired up last weekend, and I was a happy camper (boater!)

  • Congrats on getting things running. It sure will make your next docking experience less adventurous. Having run the engines dry, even briefly, and as the boat is new to you I strongly suggest you replace your raw water pick up impellers. This way you know what you have and don't have to worry if they were damaged running dry or by the previous owner.

  • If I knew where they were, I would. I'll have to look next weekend and see if I can find them, and then find replacements for them

  • It is quite simple actually. There are a couple of ways to find the pumps: One is to look at the front of the engine, the pump will be belt belt driven. The pump itself is typically mounted low and will have 2 hoses connected to it. One of the hoses will lead to the thru hull, the other to the engine at either the thermostat housing (raw water cooled) or your heat exchanger (fresh water cooled). When you get to the pump you will be able to identify the make and then the appropriate impeller.

    Got a question about those water pumps. Obviously a pump needs separated to replace the impeller. Well then - I'd expect I'll need a new gasket or o-ring for reassembly....I don't know since I don't have a breakdown of the pump's assembly, nor a positive resource for the parts. I imagine the impeller may cross to one from West Marine. I've got 1965 Pacer 220s (327 CIDs). Where do I go for the parts and is there a part number? I'm sure I can make the gaskets or match up o-rings.
