    Mercruiser 7.4L MPI Horizon distributor timing

    When I rebuilt mine last winter, #1 was slightly clockwise from from centerline of the engine, viewed toward the timing belt end. 1 tooth either way made a large difference, counterclockwise from CL, or way further clockwise. This corresponds with the diagram on page 4B-6 of the service manual...

    Xantrex TruCharge 2 Indicators

    I've been troubleshooting battery bank issues and finally located my issue, boiled almost dry it seems, but the charger does not charge after a fill, nor respond to settings changes and the 2 Stage LED is yellow. The manual does not mention anything about any yellow indicator and all others are...

    Battery drain troubleshooting

    From the Supplement wiring diagram. The Main feed at the top comes from the switched side of the main switch, stbd bank. 4 Co Monitor clearly labled.

    Battery drain troubleshooting

    The CO detectors are connected to the MDB in the DC panel which DOES go through the main switches, but no switch in the MDB to turn them off otherwise.

    Battery drain troubleshooting

    4 CO detectors FireboyXintex, 4ma draw. They could theoretically run 10+ years on 2x series 27 batteries without a charge. I don't recall seeing them in the wiring diagrams, so not sure where they connect but still should not matter. Turning off the breakers is still key. I'd rather not have to...

    Battery drain troubleshooting

    Some good points. Salt air is not generally an issue in the north chesapeake. It's super clean with minimal signs of corrosion anywhere. It went 5 months last winter with no ac power and still had plenty of charge. CO detectors are new. Alternators can be disconnected easily. Battery isolator is...

    Battery drain troubleshooting

    Post winter haul both battery banks are going stone dead within about 2 weeks. All 4 batteries are about 18mo old. Because we were going to be away when it got hauled I disconnected shore power, then it was almost 2 weeks till they hauled it. No issues with starting, so they seemed fine then...

    Looking for assist with locating raw water exhaust jacket drain plugs on my 454 MAG MPI Horizon

    If this is the same engine as mine, as the title states, there are a number of locations for drains. Depending on what exhaust manifolds you have, there could be brass plugs (3) on the bottom, plus a blue drain plug in the hose elbow. There should also be a blue drain plug in the outlet hose...

    Boat tool kit

    One thing we don't need anymore - a can of sawdust. A must have if you have a wooden hull. I cant remember all the times we stood on the bottom at belly button beach (Worton Cr MD) and rubbed sawdust over leaks in the boat I grew up on. The tarp is a brilliant idea. I've heard of other things...

    NJ ICW Current Status?

    Ryan's been through there many times in the last 2 years, so he's familiar. This trip was the first time on the Elco, which is probably a few inches shallower than his SR. He put Sonar on the Elco, so we watched the bottom the whole way. Not sure where the tide was at the time, but no depth...

    No Drain Mercruiser Exhaust Manifolds??

    I have another thread about my engine woes, which ended successfully. In that thear I mentioned that the replacement exhaust manifolds from Mercruiser came with a note saying that drains are no longer required (and missing). I am skeptical. I started the winterizing process last night, and since...

    Fuel Sender Resistance Scale

    My calibrated chart. The whole point of this exercise is to use my Axiom MFD Fuel Management data to track fuel use and not rely solely on the gauges, especially at refueling time. Now that I have calibrated it I can validate the Axiom numbers, next season.

    Fuel Sender Resistance Scale

    Yes, as noted I have reed type senders. As the float rises it makes a jump to the next value every 3/4" for a total of 25 steps. The difference between steps from mid point to the top (full) is near zero (at 6ohms/step) but from mid point down, the change increases quite a bit at each step...

    Fuel Sender Resistance Scale

    I pulled the sender and measured it last night. It is absolutely nonlinear. 25 steps at 3/4" increments. First step from bottom was a 19 ohm change, last step at top is 5.3. I'll plot and post it later. This confirms what my checks suggested.

    NJ ICW Current Status?

    I grew up on and around wooden boats. My last one was a 1962 28ft CC Constellation. 1 owner very solid, but pretty much untouched since new. We restored it to new, WL up, but then the original bottom reached a point of no return. The double bottom lasted into the 60's. My '62 and the 'family'...

    The listing is a bit optimistic! Ryan had 2 weeks of hull work & paint done before he left, plus he did thru hull fittings, hoses, bilge pumps and float switches, wiring fixes and more. Attached is my Fathers Elco, around '73 or '74, me in the middle and Ryans (late) dad on the right.

    NJ ICW Current Status?

    Oh, and he sold his SR 370SB to buy this Elco (plus a bag of money!). He was looking for a Hatteras 53, or similar, but couldn't help himself when he happened upon this Elco. We knew it was still around, but was not in Ryans sight at first. My fathers Elco was on the hard since the early 2000's...

    My nephew, Ryan, in his 50ft 1929 Elco, Liberté, the boat that this thread is about, was nearly swamped by a massive fishing boat in the Cape May inlet. It blew past him and the swell was so large it turned him into the trough, and rolled an estimated 60 degrees. It has only a 12ft beam, and a...

    Follow-up - Yard work took too long and everyone that had planned to go on the trip couldn't make it, but the weather turned perfect just in time for him to head out and make Downrigging in Chestertown. He left Toms River solo, headed out Barnegat, ran to Cape May without a hitch, almost got...
